Precision Selective Etch And The Path To 3D


Scaling (the shrinking of the tiny devices in chips such as transistors and memory cells) has never been easy, but making the next generation of advanced logic and memory devices a reality requires creating new structures at the atomic scale. When working with dimensions this small, there is little room for variation. Compounding the problem is a need to remove material isotropically, or, un... » read more

Next-Gen Transistors


Nanosheets, or more generally, gate-all-around FETs, mark the next big shift in transistor structures at the most advanced nodes. David Fried, vice president of computational products at Lam Research, talks with Semiconductor Engineering about the advantages of using these new transistor types, along with myriad challenges at future nodes, particularly in the area of metrology. » read more

Week In Review: Manufacturing, Test


Chipmakers, OEMs UMC plans to build a new fab next to its existing 300mm fab in Singapore. The new fab, called Fab12i P3, will manufacture wafers based on UMC’s 22nm/28nm processes. The planned investment for this project will be $5 billion. The first phase of this greenfield fab will have a monthly capacity of 30,000 wafers with production expected to commence in late 2024. To account fo... » read more

Transistors Reach Tipping Point At 3nm


The semiconductor industry is making its first major change in a new transistor type in more than a decade, moving toward a next-generation structure called gate-all-around (GAA) FETs. Although GAA transistors have yet to ship, many industry experts are wondering how long this technology will deliver — and what new architecture will take over from there. Barring major delays, today’s GAA... » read more

Silicon-based Power Semis Face Challenges


Suppliers of power semiconductors continue to develop and ship devices based on traditional silicon technology, but silicon is nearing its limits and faces increased competition from technologies like GaN and SiC. In response, the industry is finding ways to extend traditional silicon-based power devices. Chipmakers are eking out more performance and prolonging the technology, at least in th... » read more

Precision Selective Etch Tools Pave The Way For The Next Technology Inflection


Over the past decade, the need for increasingly smaller, denser, more powerful chips has been driving semiconductor manufacturers to move away from planar structures in favor of increasingly complex three-dimensional (3D) structures. Why? Simply put, stacking elements vertically enables greater density. Use of 3D architectures to support advanced logic and memory applications represents the ... » 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

Week In Review: Auto, Security, Pervasive Computing


Pervasive computing, IoT and 5G Infineon added to its NFC (near-field communications) IP by acquiring NFC patent portfolios from France Brevets and Verimatrix. “With this acquisition, Infineon further strengthens its IP and technology portfolio, specifically in our leadership markets for security and connectivity for the IoT,” said Thomas Rosteck, president of Infineon’s Connected Secure... » read more

Week In Review: Manufacturing, Test


Government policy As reported, the United States is in dire need of more fab capacity as well as packaging plants. The U.S. took a big step in an effort to solve the problem. The U.S. House of Representatives this week introduced the America Competes Act of 2022. The bill includes funding for the Creating Helpful Incentives to Produce Semiconductors for America (CHIPS) Act, which is earmarked... » read more

Week In Review: Manufacturing, Test


Fabs Intel has announced plans for an initial investment of more than $20 billion in the construction of two new leading-edge fabs in Ohio. Planning for the first two factories will start immediately, with construction expected to begin late in 2022. Production is expected to come online in 2025. As part of the announcement, Air Products, Applied Materials, Lam Research and Ultra Clean Technol... » read more
