Topology for Substrate Routing in Semiconductor Package Design


Abstract: In this work, we propose a new signal routing method for solving routing problems that occur in the design process of semiconductor package substrates. Our work uses a topological transformation of the layers of the package substrate in order to simplify the routing problem into a problem of connecting points on a circle with non-intersecting straight line segments. The circle, whi... » read more

Improving PPA In Complex Designs With AI


The goal of chip design always has been to optimize power, performance, and area (PPA), but results can vary greatly even with the best tools and highly experienced engineering teams. Optimizing PPA involves a growing number of tradeoffs that can vary by application, by availability of IP and other components, as well as the familiarity of engineers with different tools and methodologies. Fo... » read more

Week In Review: Manufacturing, Test


Fab tools Lam Research has rolled out a new suite of selective etch products for use in developing next-generation technologies, such as gate-all-around (GAA) transistors. In the fab, selective etch helps chipmakers with complex structures. These etch tools provide selective and precision etching without modifying or causing damage to other critical material layers. Composed of three new... » read more

200mm Shortages May Persist For Years


A surge in demand for chips at more mature process nodes is causing shortages for both 200mm foundry capacity and 200mm equipment, and it shows no signs of letting up. In fact, even with new capacity coming on line this year, shortages are likely to persist for years, driving up prices and forcing significant changes across the semiconductor supply chain. Shortages for both 200mm foundry cap... » read more

A crossbar array of magnetoresistive memory devices for in-memory computing


Samsung has demonstrated the world’s first in-memory computing technology based on MRAM. Samsung has a paper on the subject in Nature. This paper showcases Samsung’s effort to merge memory and system semiconductors for next-generation artificial intelligence (AI) chips. Abstract "Implementations of artificial neural networks that borrow analogue techniques could potentially offer low-po... » read more
