Using A Virtual DOE To Predict Process Windows And Device Performance Of Advanced FinFET Technology


By Qingpeng Wang, Yu De Chen, Cheng Li, Rui Bao, Jacky Huang, and Joseph Ervin Introduction With continuing finFET device process scaling, micro loading control becomes increasingly important due to its significant impact on yield and device performance [1-2]. Micro-loading occurs when the local etch rate on a wafer is dependent upon existing feature sizes and local pattern density. Uninten... » read more

Week In Review: Manufacturing, Test


Chipmakers Intel has outlined its new process technology roadmap with plans to regain the leadership position in the market. As part of the move, Intel has changed the way it designates the nodes, revealed its new gate-all-around (GAA) transistor, and disclosed a customer for the GAA technology--Qualcomm. And not to be outdone, Intel has broadened its packaging portfolio. Intel is changing ... » read more

MEMS: New Materials, Markets And Packaging


Semiconductor Engineering sat down to talk about future developments and challenges for microelectromechanical systems (MEMS) with Gerold Schropfer, director of MEMS products and European operations in Lam Research's Computational Products group, and Michelle Bourke, senior director of strategic marketing for Lam's Customer Support Business Group. What follows are excerpts of that conversation.... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs The industry is still wondering if Intel will buy GlobalFoundries (GF). In the meantime, GF has announced a fab expansion plan in upstate New York. These plans include immediate investments at its existing Fab 8 facility as well as construction of a new fab on the same campus. That will double the capacity at the site. Intel has reported its second-quarter 2021 financial... » read more

Chip Shortages Grow For Mature Nodes


The current wave of chip shortages is expected to last for the foreseeable future, particularly for a growing list of critical devices produced in mature process nodes. Chips manufactured at mature nodes typically fall under the radar, but they are used in nearly every electronic device, including appliances, cars, computers, displays, industrial equipment, smartphones, and TVs. Many of thes... » read more

MicroLEDs Moving From Lab to Fab


Every disruptive technology has its "aha" moment — the time when everyone from engineers to investors realizes that, yes, this technology is the real deal and it won’t be scrapped on the R&D floor. For many, it was Samsung’s recent announcement of a 110-inch microLED TV that irrevocably put microLEDs on the map. The TV’s price is $155,000, but as with most consumer electronics th... » read more

Using Less Helium In Semiconductor Manufacturing


Helium gas is increasingly in short supply. While consumers may be most familiar with it for use in filling balloons, it is used much more heavily in a variety of industrial processes – including semiconductor fabrication. As a result of supply concerns, many companies, including Lam, are looking for ways to reduce their helium usage. The making of a semiconductor chip involv... » read more

Piecing Together Chiplets


Several companies are implementing the chiplet model as a means to develop next-generation 3D-like chip designs, but this methodology still has a long way to go before it becomes mainstream for the rest of the industry. It takes several pieces to bring up a 3D chip design using the chiplet model. A few large players have the pieces, though most are proprietary. Others are missing some key co... » read more

Blog Review: July 21


Cadence's Paul McLellan listens in as Partha Ranganathan of Google argues that a new era of Moore's Law is emerging, defined both by the efficient design of hardware accelerators and improving the ways that hardware is utilized. Siemens EDA's Chris Spear continues exploring classes in SystemVerilog with a look at the relationship between the class variables that point to an object and how to... » read more
