Research Bits: November 14


Solid-state thermal transistor for heat management Researchers from University of California Los Angeles created a stable and fully solid-state thermal transistor that uses an electric field to control a semiconductor device’s heat movement. It is compatible with integrated circuits in semiconductor manufacturing processes. The team’s design incorporates the field effect on charge dynamics... » read more

Total Overlay With Multiple RDLs


As Advanced IC Substrates (AICS) add more RDL layers, requiring additional via connections between the RDL layers, the potential for cumulative overlay shift increases. This overlay shift can lead to longer RDL traces, which increases interconnect resistance, resulting in lower yield. Keith Best, director of product marketing, for lithography at Onto Innovation, talks about total overlay — th... » read more

DRAM Choices Are Suddenly Much More Complicated


Chipmakers are beginning to incorporate multiple types and flavors of DRAM in the same advanced package, setting the stage for increasingly distributed memory but significantly more complex designs. Despite years of predictions that DRAM would be replaced by other types of memory, it remains an essential component in nearly all computing. Rather than fading away, its footprint is increasing,... » read more

Is Your Voltage Drop Flow Obsolete?


Voltage drop at advanced nodes is a deadly serious problem that has become unmanageable with the methodologies used by most chip designers today. This article will cover the reasons why power integrity has risen to a top-of-mind concern and why it has become almost impossible for today’s EDA tools to measure and fix it. We will then look at some radical methodology rethinking that is needed t... » read more
