Revenue in Q1 2018 increased 2.5% as compared to Q1 2017, gross profit margin improved by 1.2 percentage points, gross margin dollars increased by 7.2%, operating income rose 15.9% and Adjusted EBITDA was higher by 18.4% as compared to the first quarter a year ago. Revenue from lower-margin products in the non-OLED portion of the Display business line decreased in Q1 due to a strategic portfolio optimization initiative to improve product mix and profitability over time. CFO Kim added, “Our results in Q1 demonstrated our ongoing commitment to focus on achieving profitable growth.”

First Quarter Financial Review
Total Revenue
Total revenue in the first quarter of 2018 was $165.8 million, up 2.5% as compared to $161.7 million from the first quarter of 2017, and down 5.0% from the fourth quarter of 2017.

Segment Revenue and Segment Adjustments
In January 2018, as part of the Company’s ongoing portfolio optimization effort to realign business processes and streamline the organizational structure, the Company transferred a portion of the non-OLED Display business, which was $4.4 million for Q1 2018, from the Standard Products Group to the Foundry Services Group. The transferred non-OLED Display business has characteristics more closely aligned with the Foundry business than with Standard Products and resided within the Display business line primarily as a result of a long standing customer relationship established many years ago. The historical financial results below are discussed both on an as reported and as adjusted basis for comparative purposes.

Foundry Services Group revenue in the first quarter was $77.4 million, about flat with reported revenue of $77.5 million from the first quarter of 2017, and down 4.0% from the fourth quarter of 2017 on an as reported basis; and down 7.3% from the first quarter of 2017, and down 14.2% from the fourth quarter of 2017 on an as adjusted basis.

Following the strategic realignment and portfolio optimization discussed above, Standard Products Group revenue in the first quarter of 2018 was $88.4 million, up 5.0% year-over-year and down 5.9% sequentially on an as reported basis; and up 13.1% year-over-year and up 4.8% sequentially on an as adjusted basis. The improved results in the Standard Products Group reflected an improvement in mobile OLED driver revenue in connection with the introduction of new OLED smartphones from China manufacturers, higher demand for MOSFETS for mobile battery and television products, despite lower LCD display driver revenue. The sequential revenue decline in Q1 2018 as compared with the fourth quarter of 2017 stemmed primarily from a previously announced strategic plan to reduce business from lower-margin LCD display drivers in the Standard Products Group.

Total Gross Profit and Gross Profit Margin
Total gross profit in the first quarter of 2018 was $44.6 million or 26.9% as a percentage of sales as compared with gross profit of $41.6 million or 25.7% gross profit margin in the first quarter of 2017, and $49.4 million or 28.3% gross profit margin for the fourth quarter of 2017.

Segment Gross Profit Margin
Foundry Services Group gross profit margin was 26.7% in the first quarter of 2018 as compared with, on an as reported basis, 28.5% in the first quarter of 2017 and 31.7% in the fourth quarter of 2017. The Foundry Services Group gross profit margin was, on an as adjusted basis, 27.9% in the first quarter of 2017 and 30.4% in the fourth quarter of 2017.

SEOUL, South Korea and SAN JOSE, Calif., March 19, 2018 /PRNewswire/ — MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX), a designer and manufacturer of analog and mixed-signal semiconductor products, announced today that it now offers a 0.18 micron BCD (Bipolar-CMOS-DMOS) 100V high voltage process. The features of this new BCD process compare favorably with previous generations of process technology.

The new BCD process requires three fewer layers of photo steps by process optimization, and has low specific on-resistance (Rsp) of power LDMOS (Laterally Diffused Metal Oxide Semiconductor) up to 100V. Having 100V devices in BCD process is valuable as there are increasing demands to expand operation voltages and protection voltages to 100V in many applications, such as Power over Ethernet (PoE), AC-DC chargers, solar panel power ICs, and automotive battery systems. In addition, the new BCD process offers automotive-grade reliability for DC-DC converters, LED drivers, motor drivers, battery chargers, and PMICs used in automotive electronics.

In power ICs that use BCD technologies, the area of power transistors like LDMOS occupies major chip area. And the specific on-resistance of power transistors — which is defined as the product of total on-resistance and area of the device when a transistor is turned on — is the key factor that determines overall chip area. As a specialty analog foundry, MagnaChip has improved the specific on-resistance over the past 10 years to assist foundry customers achieve smaller chip sizes and reduce costs. Utilizing MagnaChip’s proprietary deep-trench isolation technology and advanced device designs, the low specific on-resistance of 100V operation LDMOS was achieved on conventional silicon substrates without the use of more expensive SOI (Silicon-On-Insulator) substrates. Overall, with these process advantages, this new 0.18 micron BCD 100V high voltage process can enhance cost effectiveness of customers’ products.

To support power ICs for various applications like consumer, industrial, and especially automotive applications, this process technology was qualified based on the automotive-grade-qualification specification of AEC-Q100 with Grade1 temperature condition between -40 to 125 °C.

There are option devices in the new 0.18 micron BCD process to enhance design integration and flexibility. The option devices include a high performance bipolar transistor, high resistance poly resistor, tantalum nitride resistor with low temperature coefficient, metal-insulator-metal capacitor, metal-oxide-metal capacitor, electrical fuse, and multi-time programmable memory.

YJ Kim, Chief Executive Officer of MagnaChip, commented, “We are very pleased to offer our 0.18 micron BCD 100V process solution that combines both the advantages of high-performance as well as high reliability.” Mr. Kim added, “Our goal is to continue to develop technologies with high performance and high reliability to cover a broad range of applications for our foundry customers”.

SEOUL, South Korea and SAN JOSE, Calif., Feb. 12, 2018 /PRNewswire/ — MagnaChip Semiconductor Corporation (“MagnaChip” or the “Company”) (NYSE: MX), a designer and manufacturer of analog and mixed-signal semiconductor platform solutions, announced today it now offers the 2nd generation of 0.13 micron BCD process technology integrated with high-density embedded Flash memory. This second-generation BCD process offers advanced features compared to previous BCD processes, which are high-density Flash memory up to 64 kilo bytes, low specific Ron of power LDMOS up to 40V, low number of photo steps and automotive grade reliability. These characteristics make the new generation of BCD process technology highly suitable for programmable PMICs, wireless power chargers, USB-C power-delivery IC products and automotive power ICs.

Traditionally, the non-volatile memories in the BCD process are low in density, below 256 bytes, for trimming purposes. However, today’s electronic devices require more complex functions and lower power consumption. As a result, there is a greater market need for high-density embedded non-volatile memory in the BCD process. This memory includes Flash memory used for power ICs, including programmable PMICs, wireless power chargers and USB-C power-delivery ICs. In some applications, high-density Flash memory up to 64 kilo bytes is used to store programming codes as well as trimming data. Until now, the drawback of implementing high-density embedded memory in other BCD processes has been that it increases the overall number of manufacturing steps.

MagnaChip was able to eliminate 8 photo steps in the second-generation BCD process from the 1st generation by process optimization. Aside from embedded non-volatile memory, the 2nd generation also achieved the improvement of power LDMOS specific Ron performance, which is well suited for high-power requirements up to 40V operation. For IoT and automotive applications, this BCD process provides 1.5V and 5V CMOS devices with very low leakage current level that enables low power consumption. Furthermore, this new BCD process has various option devices for Hall sensors, varactors, inductors, and RF CMOS devices that are useful for highly integrated IC solutions, which give smaller system size and less system cost.

YJ Kim, Chief Executive Officer of MagnaChip, commented, “The integration of analog-based BCD and high density non-volatile memory enables highly suitable ICs and system designs for power management solutions, wireless chargers and power ICs used in smartphones, IoT devices and automotive applications.” Mr. Kim added, “Our goal is to continue to develop specialized and innovative process technologies that meet the changing market requirements of our foundry customers.”

SEOUL, South Korea and SAN JOSE, Calif., Jan. 8, 2018 /PRNewswire/ — MagnaChip Semiconductor Corporation (“MagnaChip”) (NYSE: MX), a designer and manufacturer of analog and mixed-signal semiconductor platform solutions, today announced it now offers a multi-level thick IMD (Inter-Metal Dielectric) process for a capacitor with ultra-high breakdown voltage. This capacitor is useful for the digital isolation and capacitive coupling in electronic circuits.

Demand for digital isolators is growing for noise-immune electronics products commonly found in electric vehicles and in industrial, communications and healthcare applications as a substitute for conventional optocouplers. Digital isolators demonstrate superior performance and reliability and can achieve higher levels of integration at lower cost, as compared to optocouplers. Industry analyst expects the worldwide digital isolator market will reach approximately $2 billion by 2023 at a CAGR (Compound Annual Growth Rate) of six percent between 2017 and 2023.

MagnaChip’s multi-level thick IMD process consists of back-end-of-line process module including IMD with a thickness from 5um to 6um per metal layer. Depending on the breakdown and capacitance requirements, the thick IMD can be stacked together up to three layers to allow the design of the metal-insulator-metal capacitor with insulator thickness in the range of 5um to 20um. This capacitor will withstand from about 4 kilo-volts to 15 kilo-volts before breakdown, which is suitable for capacitive isolation of a digital signal from ultra-high voltage noise from outside environments.

The multi-level thick IMD process module, which has already passed the reliability requirements for automotive AEC Q-100, is now integrated into MagnaChip’s 0.18um BCD and Mixed Signal process technologies. The Process Design Kit is available to support on-chip integration.

YJ Kim, MagnaChip’s Chief Executive Officer, commented “We are very pleased to provide a special multi-level thick IMD process for ever-growing capacitive isolation applications. This is a significant addition to our many specialty process technologies.” Mr. Kim added, “We will continue to provide innovative and differentiated technologies to meet the fast-changing needs of our foundry customers.”
