Welcome To The ‘Probably Good Die’ Era

By Mark LaPedus In today’s systems, consumers want more performance and bandwidth with a longer battery life. Some chip segments are keeping up with the demands. Still other areas are falling way behind the curve. Battery life is an obvious problem, but memory bandwidth is under the radar. “Initially, memory bandwidth nearly doubled every two years, but this trend has slowed over the pa... » read more

Foundry Landscape Changes In 3D

By Mark LaPedus Over the last year, leading-edge silicon foundries announced their new and respective strategies in the emerging 2.5D/3D chip arena. The ink is barely dry and now the foundry landscape is changing. One new vendor, Tezzaron Semiconductor, is entering the market. The 3D DRAM supplier plans to provide select 2.5D/3D foundry services within its recently acquired fab in Austin, T... » read more

The Changing Role Of The OSAT

By Ann Steffora Mutschler As process geometries and packaging technologies have matured over time, the OSAT (outsourced semiconductor assembly and test) provider has played an evolving role in the semiconductor packaging ecosystem. With true 3D chip stacking on the horizon, their role may evolve once again as ecosystem players jostle for position in the 3D universe. There are two things tha... » read more

Testing the Waters

By Ann Steffora Mutschler Large semiconductor companies are now testing the waters in 3D design to determine how to best leverage the technology for lower power, better performance and additional architectural flexibility. As such, much work is being done to determine how exactly to achieve an optimum 3D design outcome. 3D is almost by definition an architectural approach to power sav... » read more

Architectural Changes Will Drive Miraculous 3D Gains

By Ann Steffora Mutschler Low-Power High-Performance Engineering sat down with Robert Patti, chief technology officer at Tezzaron Semiconductor, to discuss future challenges with regard to 2.5D and 3D design, including making tradeoffs and technical issues specific to 3D design. Tezzaron currently is working on 3D designs. LPHP: What is the starting point technically to achieve the gre... » read more
