What Machine Learning Can Do In Fabs


Semiconductor Engineering sat down to discuss the issues and challenges with machine learning in semiconductor manufacturing with Kurt Ronse, director of the advanced lithography program at Imec; Yudong Hao, senior director of marketing at Onto Innovation; Romain Roux, data scientist at Mycronic; and Aki Fujimura, chief executive of D2S. What follows are excerpts of that conversation. L-R:... » read more

Memory Issues For AI Edge Chips


Several companies are developing or ramping up AI chips for systems on the network edge, but vendors face a variety of challenges around process nodes and memory choices that can vary greatly from one application to the next. The network edge involves a class of products ranging from cars and drones to security cameras, smart speakers and even enterprise servers. All of these applications in... » read more

Improving EUV Process Efficiency


The semiconductor industry is rethinking the manufacturing flow for extreme ultraviolet (EUV) lithography in an effort to improve the overall process and reduce waste in the fab. Vendors currently are developing new and potentially breakthrough fab materials and equipment. Those technologies are still in R&D and have yet to be proven. But if they work as planned, they could boost the flo... » read more

Scaling Up Compute-In-Memory Accelerators


Researchers are zeroing in on new architectures to boost performance by limiting the movement of data in a device, but this is proving to be much harder than it appears. The argument for memory-based computation is familiar by now. Many important computational workloads involve repetitive operations on large datasets. Moving data from memory to the processing unit and back — the so-called ... » read more

The Ins And Outs Of Silicon Carbide


John Palmour, CTO at Cree, sat down with Semiconductor Engineering to talk about silicon carbide, how it compares to silicon, what's different from a design and packaging standpoint, and where it's being used. What follows are excerpts of that conversation. SE: SiC is well-understood in power electronics and RF, but is the main advantage the ability to run devices hotter than silicon, or is ... » read more

Chiplet Momentum Rising


The chiplet model is gaining momentum as an alternative to developing monolithic ASIC designs, which are becoming more complex and expensive at each node. Several companies and industry groups are rallying around the chiplet model, including AMD, Intel and TSMC. In addition, there is a new U.S. Department of Defense (DoD) initiative. The goal is to speed up time to market and reduce the cost... » read more

2020 IC Outlook: Uncertainty


After a downturn in 2019, the semiconductor and equipment industries looked promising at the start of 2020. In 2019, the downturn was primarily due to the memory markets, namely DRAM and NAND. Both DRAM and NAND saw lackluster demand and falling prices last year. At the start of 2020, though, the memory markets were beginning to recover. Unlike memory, the logic and foundry markets were s... » read more

MOCVD Vendors Eye New Apps


Several equipment makers are developing or ramping up new metalorganic chemical vapor deposition (MOCVD) systems in the market, hoping to capture the next wave of growth applications in the arena. Competition is fierce among the various MOCVD equipment suppliers in the market, namely Aixtron, AMEC and Veeco. In addition, MOCVD equipment suppliers are looking for renewed growth in 2020, but b... » read more

Moving To GAA FETs


How do you measure the size of a transistor? Is it the gate length, or the distance between the source and drain contacts? For planar transistors, the two values are approximately the same. The gate, plus a dielectric spacer, fits between the source and drain contacts. The contact pitch, limited by the smallest features that the lithography process can print, determines how many transistors ... » read more

Demand Picks Up For 200mm


Demand is growing for both 200mm fab capacity and equipment, setting the stage for possible shortages in coming months. But there are also some uncertainties, if not warning signs, in the 200mm market and the entire IC industry. Trade disputes, as well as the current coronavirus outbreak in China, likely will impact the chip and equipment markets. The size of the impact and the duration rema... » read more
