• Process technologies for higher power and higher temperature power management applications to be discussed at 2006 FSA Suppliers Expo - Taiwan, Booth#A36

Zarlink Semiconductor (NYSE/TSX:ZL) today announced the release of an enhanced WPX and WPY process with a high beta early voltage lateral PNP transistor. The improved capabilities of the lateral PNP transistor allow designers to use the WPX and WPY process technologies in a wider range of power management applications requiring both higher operating power and temperature performance.

"We have developed an improved transistor with up to twice the beta VA product and more consistent voltage output over a range of input currents," said Dr. Peter Osborne, chief technology officer, Zarlink Analog Foundry. "This power management performance enhancement is in direct response to requirements from customers who are using our process technologies in increasingly demanding applications."

Building on its expertise in RF process technology, the Zarlink Analog Foundry has developed a power management process with greater than 20 V (volt) capability at a transistor transit frequency of 5 GHz. Zarlink developed the WP series fully featured 15-layer process specifically for industrial power management applications, including dc-dc power bricks, mobile telephone battery power management and all linear power management applications.

Zarlink Analog Foundry will be discussing its improved WPX and WPY process technologies at the 2006 FSA Suppliers Expo and Conference in Taipei, Taiwan on Wednesday, November 8th (Booth#A36).

WPX and WPY process technologies

The WP series is a versatile low capacitance linear bipolar process providing excellent functionality at low cost. Features such as high-value poly resistors and nitride capacitors and two-layer metal allow low current circuits to be built with high packing densities. The technologies are suitable for greater than 20 V and 22 V power management applications. The current range of onboard components, including Schottky diodes, high-value capacitors, resistors, thick metal and improved lateral PNP transistors, combined with fast, high-performance NPN transistors are all designed to provide characteristically low leakage and flicker noise.

The WP series process technologies are supported by a comprehensive design kit and technical support service. The Foundry's Design Services group is a broad-based team with significant experience and expertise in IC design support, including a comprehensive autographics (chip finishing and tape out) service and ESD (electrostatic discharge) consultation. The team develops and supports front-end to back-end design capabilities and models that enables IC design on industry-standard design tools. A complete "plug and play" design environment will also be offered, comprising schematic capture, simulation and layout, together with a comprehensive DRC and LVS design verification suite.

Zarlink's WP-process technology is available for low-cost prototyping using a multi-project wafer processing service. For further information, visit: http://foundry.zarlink.com/ or contact Steve Mace, technical marketing, Zarlink Analog Foundry at steve.mace@zarlink.com.
