Speeding Up Process Optimization Using Virtual Fabrication


Author: Joseph Ervin Director, Semiconductor Process and Integration Lam Research Advanced CMOS scaling and new memory technologies have introduced increasingly complex structures into the device manufacturing process. For example, the increase in NAND memory layers has achieved greater vertical NAND scaling and higher memory density, but has led to challenges in high aspect ratio etch patte... » read more

Non-Volatile Memory Tradeoffs Intensify


Non-volatile memory is becoming more complicated at advanced nodes, where price, speed, power and utilization are feeding into some very application-specific tradeoffs about where to place that memory. NVM can be embedded into a chip, or it can be moved off chip with various types of interconnect technology. But that decision is more complicated than it might first appear. It depends on the ... » read more

Transient Thermal Analysis For M.2 SSD Thermal Throttling: Detailed CFD Model vs Network-Based Model


Solid State Drive (SSD) technology continues to advance toward smaller footprints with higher bandwidth and adoption of new I/O interfaces in the PC market segment. Power performance requirements are tightening in the design process to address specific requirement along with the development of SSD technology. To meet this aggressive requirement of performance, one major issue is thermal throttl... » read more

Week In Review: Manufacturing, Test


Market research The worldwide semiconductor market is forecast to reach $409 billion in 2019, down 12.8% over 2018, according to the World Semiconductor Trade Statistics (WSTS) organization. Memory fell by 33.0% in 2019, while analog dropped 7.9% and logic declined by 4.3%, according to the WSTS. In 2020, the IC market is expected to recover and grow by 5.9%, according to the WSTS.

Why Standard Memory Choices Are So Confusing


System architects increasingly are developing custom memory architectures based upon specific use cases, adding to the complexity of the design process even though the basic memory building blocks have been around for more than half a century. The number of tradeoffs has skyrocketed along with the volume of data. Memory bandwidth is now a gating factor for applications, and traditional memor... » read more

The Next New Memories


Several next-generation memory types are ramping up after years of R&D, but there are still more new memories in the research pipeline. Today, several next-generation memories, such as MRAM, phase-change memory (PCM) and ReRAM, are shipping to one degree or another. Some of the next new memories are extensions of these technologies. Others are based on entirely new technologies or involve ar... » read more

Cloudy Outlook Seen For IC Biz


After a slowdown in the first half of 2019, chipmakers and equipment vendors face a cloudy outlook for the second half of this year, with a possible recovery in 2020. Generally, the semiconductor industry began to see a slowdown starting in mid- to late-2018, which extended into the first half of 2019. During the first half of this year, memory and non-memory vendors were negatively impacted... » read more

China’s Latest Goal—More DRAMs


China is once again making a concerted effort to get its domestic DRAM industry off the ground. Past efforts have fallen short or failed. This time around, it’s unclear if China will succeed, but the industry should pay close attention here. So why would China want to play a bigger role in the tough and competitive DRAM business? For one thing, the U.S. and China are in the midst of a t... » read more

Falling Chip Forecasts


It’s time to take a pulse of the semiconductor market amid the memory downturn and trade frictions with China. For some time, the DRAM and NAND markets have been hit hard with falling prices and oversupply. Then, the Trump administration last year slapped tariffs on Chinese goods. China retaliated. And the trade war rages on between the U.S. and China. More recently, the U.S. Department... » read more

Memory Options And Tradeoffs


Steven Woo, Rambus fellow and distinguished inventor, talks with Semiconductor Engineering about different memory options, why some are better than others for certain tasks, and what the tradeoffs are between the different memory types and architectures.     Related Articles/Videos Memory Tradeoffs Intensify In AI, Automotive Applications Why choosing memories and archi... » read more
