RIVERSIDE, Calif. and SEOUL, South Korea, Sept. 27, 2011 – MagnaChip Semiconductor Corporation (“MagnaChip”) (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, and Bourns, Inc. (“Bourns”), a leading manufacturer and supplier of electronic components announced today that MagnaChip has ramped to mass production all families of the Bourns® series of high-speed circuit protection devices (TBU® HSP) designed for a broad selection of Industrial, Consumer and Telecommunication applications.

TBU® HSP devices are constructed using MOSFET semiconductor technology. When placed in series in the system, the TBU® HSP device monitors the current flowing through the line. If the current exceeds a preset level, the TBU® HSP device triggers in less than 1 microsecond, providing an effective barrier to large, destructive voltages or currents during surge events, thereby protecting sensitive electronics. These devices are particularly popular in Telecommunication applications (such as Voice SLICs, xPON and GBEthernet), Industrial applications (such as RS485 interfaces, surveillance systems and avionics) and Consumer products applications (such as set top boxes and home gateways).

The TBU® HSP devices are custom designed and developed using Bourns’ proprietary technology fabricated by MagnaChip. MagnaChip successfully transferred two proprietary processes of Bourns needed to produce the TBU® HSP devices by closely working with Bourns’ engineering team. Both processes are currently in the production ramp phase.

TJ Lee, Senior Vice President and General Manager of MagnaChip’s Corporate and SMS Engineering, commented, “We are very pleased to have successfully transferred the Bourns processes to production. We also look forward to supporting their future engineering and manufacturing needs as a partner for our foundry services.”

Arnaud Moser, General Manager of Bourns’ Telecom Segment, added, “We are happy to celebrate this milestone with MagnaChip and look forward to a continued, successful partnership. Thanks to MagnaChip’s engineering expertise and state of the art production facilities, Bourns has been able to bring this innovative technology to a broad array of customers across many markets.”

SEOUL, South Korea and CUPERTINO, Calif., Sept. 19, 2011 – MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, has launched a series of 4 channel LED drivers for use in LED monitors and LED-TV applications

These new device drivers from MagnaChip are designed to fit the back light unit structures of the latest LED monitors and televisions. Each channel has the equivalent of a 150mA/65V current balance MOSFET embedded in it that is capable of driving up to 20 LEDs in a 40W LED backlight unit.

Operating efficiency and safety have been enhanced through a multitude of designed-in protection functions including current overload protection, LED open/short protection, over voltage protection, open Schottky diode protection and others. The new products are offered in various package and performance options and specifications can be found on the company’s website at www.magnachip.com.

HK Kim, executive vice president of MagnaChip’s Power Solutions Division stated, “There is advanced technology behind the development and launch of all of our new products, including our latest 4-channel LED driver. We intend to continue to innovate and expand the delivery of new and competitive LED driver devices into the 3D TV and Smart TV markets which we see as providing significant growth opportunities for our Power Solutions business.”

SEOUL, South Korea, Sept. 12, 2011 – MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed signal semiconductor products, today announced that it will offer high density metal-insulator-metal capacitor and deep trench capacitor processes for integration into MagnaChip’s standard CMOS mixed signal process.

The high density metal-insulator-metal capacitor process provides capacitance values of 4, 6, 8, and 10fF/um(2). This process replaces the industry standard silicon nitride insulator layer with a high dielectric constant material layer in order to achieve high capacitance per unit area while suppressing leakage current. This high density capacitor can substantially reduce die area in applications that need high total capacitance for the purpose of charge storage and noise decoupling.

The deep trench capacitor consists of an array of small deep trenches constructed into the silicon substrate. This 3-D capacitor has high capacitance of 22 fF/um(2) and breakdown voltage of 25V. This process is specifically optimized to make series resistance low enough for fast switching applications and will be released for production in December 2011.

TJ Lee, Senior Vice President and General Manager of MagnaChip’s Corporate and SMS Engineering stated, “We are very pleased to announce the offering of our specialty capacitor processes such as high density MIM capacitor and deep trench capacitor for feature-rich and cost-effective mixed signal applications. Our goal is to continue to develop highly differentiated and cost-effective technology solutions to meet the increasing application specific needs of our foundry customers.”
