Fourth Quarter 2018 and Recent Company Highlights

MagnaChip announced:

• The introduction of a new High-Voltage Super Junction MOSFET with a 900V breakdown voltage and low total gate charge (Qg). The device with two package types, I-PAK and D-PAK, will be manufactured in high volume in the first quarter of 2019. http://www.magnachip.com/aboutus/aboutus_sub12_view.html?tname=ez_Press_Room_e&seq=223&page=1
  
• Volume production of a new Display Driver IC (DDIC) for automotive panel displays has commenced. MagnaChip is planning to expand its business to various automotive display applications, starting with the design-win of a new product at a leading Japanese panel maker of automotive CSD (Center Stack Display) panels. The application of this LCD-based display driver product will be further extended to a wide range of automotive applications such as instrument cluster, GPS navigation and car entertainment displays in the future. Over time, it is widely anticipated that OLED display drivers also will be adopted for use in automotive applications.

• Appointment of Jeong Ki Min to the newly created position of Chief of Strategic Planning. Mr. Min, a seasoned semiconductor executive with 33 years of global business experience, previously held senior positions at Samsung Semiconductor, Samsung Electronics, Samsung Display, and SK Telecom. During his more than three decades in the high-tech industry, Mr. Min has initiated and negotiated high-profile joint venture agreements, strategic alliances and acquisitions. Among his other accomplishments, Mr. Min also has led new business planning teams, managed R&D operations, led Foundry marketing teams, and helped develop semiconductor growth strategies.

• It now offers Foundry customers a 0.18 micron BCD (Bipolar-CMOS-DMOS) 200V high-voltage process. This new BCD process uses SOI (Silicon On Insulator) substrates with solid high-voltage isolation and extends MagnaChip's existing BCD processes from 100V to 200V. Having 200V devices in a BCD process is valuable because it enables a Power IC to be designed for high voltage applications, including automobiles, electrical vehicles, industrial motor drivers, ultrasonic medical imaging systems and solar panels. http://www.magnachip.com/aboutus/aboutus_sub12_view.html?tname=ez_Press_Room_e&seq=227&page=1 
  
• Volume production has commenced for an IGBT product for power module targeted to high-voltage industrial applications. IGBT is one of a MagnaChip family of Power standard products called Insulated Gate Bipolar Transistors.The new IGBT P-series ("MBW100T120PHF") allows designers to operate devices at an improved switching frequency, which enables reducing the size and cost of capacitors and inductive devices in circuits. http://www.magnachip.com/aboutus/aboutus_sub12_view.html?tname=ez_Press_Room_e&seq=228&page=1 
  
• The appointment of Nader Tavakoli as its new non-executive Chairman of the Board of Directors, effective November 26, 2018. Mr. Tavakoli replaces Gary Tanner as the Company's Chairman. Mr. Tanner will remain a Director on the Board and will continue to serve as a member of the Audit, Compensation and Risk Committees of the Board.

• The release of a low noise, low power consumption, fast transient LDO (Low Dropout) regulator that also can be designed into BGA (Ball Grid Array) SSD (Solid State Drive) components commonly used in mobile devices. An LDO regulator is a power standard product whose function can be designed into various components. http://www.magnachip.com/aboutus/aboutus_sub12_view.html?tname=ez_Press_Room_e&seq=230&page=1
  
• Availability of its third generation 0.18 micron Bipolar-CMOS-DMOS (BCD) process technology for Foundry customers. The technology is highly suitable for PMIC, DC-DC converters, battery charger ICs, protection ICs, motor driver ICs, LED driver ICs and audio amplifiers. http://www.magnachip.com/aboutus/aboutus_sub12_view.html?tname=ez_Press_Room_e&seq=231&page=1.
