Release Film Boosts IC Molding Productivity Kenji Tsuda, Asia Contributing Editor - 07/23/2008
Asahi Glass has developed a release film for molding thin ball grid arrays (BGAs) or chip-scale packages (CSPs). The company said the film reduces resin usage, and nearly eliminates the frequent mold cleanings required with conventional molding technologies. More
Molding Techniques Support Thin Gold Wires, Low-k Materials Kenji Tsuda, Asia Contributing Editor - 07/21/2008
Competing Japan-based molding machine manufacturers have developed techniques that support the thinner packages required for cell phones. The new molding methods also ease the mechanical pressure placed on the relatively fragile low-k dielectric materials in leading-edge logic devices.

Roadmap Signals Showstoppers Laura Peters, Editor-in-Chief - 07/17/2008
The overall theme of the 2008 update to the International Technology Roadmap for Semiconductors (ITRS) is a slight slowdown of gate-length scaling for high-performance and low-standby power devices, but the low-power device target dates will not change.

High-Density Packaging Possibilities Karl Stuber, Senior Director, Test, Assembly and Packaging, SEMI, San Jose - 07/15/2008
A recent analysis of a high-end cell phone found 65 active single and multi-chip packages (MCPs) with I/Os ranging from 2 to 447 pins, with the large majority having <200 I/Os. Mobile device manufacturers today are incorporating more than 30 wafer-level chip-scale packages (WLCSPs) into their high-end cell phones.

Wire Bond Tester Targets Zero Field Failures Laura Peters, Editor-in-Chief - 07/15/2008
It may soon be possible to non-destructively test wire bond quality in real time during automated wire bonding and “bin” the failures, as is possible in electrical test.
