Week In Review: Manufacturing, Test


Chipmakers and OEMs Micron will cease development of 3D XPoint, a next-generation memory technology. Micron also plans to sell a fab that produces 3D XPoint chips. For some time, Intel and Micron have co-developed 3D XPoint, which is based on phase-change memory technology. Intel sells solid-state storage drives (SSDs) using 3D XPoint. In a fab located in Utah, Micron is producing this memo... » read more

Why New Photoresist Technology Is Critical


As chipmakers move to advanced technology nodes, they are challenged to resolve ever finer features. One of the major roadblocks involves the material used to transfer chip design to the wafer. That material is rapidly reaching its limit to accurately transfer designs. To keep next-generation device scaling on track, a breakthrough technology has been introduced: dry resist. To better understan... » read more

Long Lead Times Seen For Equipment


There are a number of big stories in the semiconductor market thus far in 2021. Automotive chip shortages and tight foundry capacity are among the bigger ones. That’s just for starters. What hasn’t received much attention is the ongoing shortages and long lead times for semiconductor equipment. In some cases, lead times have stretched out to 12 months or more for some equipment. Some t... » read more

Meeting The Challenges Of 5G RF Production Test Services


Implementation of the 5G radio frequency (RF) standard is increasing rapidly [1]. Over the past four to six quarters, there has been an increased focus on publications and products that have been introduced to the marketplace. Some of the more popular RF eco-system applications include cellphone, Wi-Fi, automotive, Internet of Things (IoT), location services, and more. Wi-Fi and cellphone servi... » read more

Overcoming Challenges In Next-Generation SRAM Cell Architectures


Static Random-Access Memory (SRAM) has been a key element for logic circuitry since the early age of the semiconductor industry. The SRAM cell usually consists of six transistors connected to each other in order to perform logic storage and other functions. The size of the 6T (6 Transistors) SRAM cell has shrunk steadily over the past decades, thanks to Moore’s Law and the size reduction of t... » read more

Chasing After Carbon Nanotube FETs


Carbon nanotube transistors are finally making progress for potential use in advanced logic chips after nearly a quarter century in R&D. The question now is whether they will move out of the lab and into the fab. Several government agencies, companies, foundries, and universities over the years have been developing, and are now making advancements with carbon nanotube field-effect transi... » read more

The Future Of Transistors And IC Architectures


Semiconductor Engineering sat down to discuss chip scaling, transistors, new architectures, and packaging with Jerry Chen, head of global business development for manufacturing & industrials at Nvidia; David Fried, vice president of computational products at Lam Research; Mark Shirey, vice president of marketing and applications at KLA; and Aki Fujimura, CEO of D2S. What follows are excerpt... » read more

Reshoring Vital To The Future Of Chipmaking


Repatriating offshore manufacturing efforts to the United States – i.e., “reshoring” – is not a new concept. The Reshoring Initiative was founded in 2010, and the Reshoring Institute, founded in 2014, conducts annual surveys of global manufacturers regarding their reshoring plans. The institute’s 2019 survey found that, while a growing number of businesses were rethinking their global... » read more

IC Materials For Extreme Conditions


The number of materials being researched for chips used in extreme environments, such as landing on the planet Venus, is growing. While GaN has captured much of the attention for power conversion circuits, it's just one of several applications for semiconductors in extreme environments. The high voltage, high temperature, and caustic atmospheres found in many industrial and aerospace environ... » read more

ALD Coatings For Critical Chamber Components


With each transition to a new technology node, fab requirements for metal and particle contamination become more stringent, posing challenges for existing coating methods such as anodization or plasma spray that may not provide complete protection against contamination especially on critical chamber components with complex geometry. SEMI spoke with Beneq business executive Sami Sneck about... » read more
