TSMC: Rise of the “Phantom Node”


TSMC’s financial results for Q4 of 2014 and for the full year were announced in January with TSMC stating it again had achieved record sales and profits. The fourth quarter saw TSMC set records for revenue, earnings per share and cash balance. TSMC made bold predictions last year about 20nm revenue by Q4 2014, and it appears it has met them (see 28nm Powers TSMC Forward, Part Deux). TSMC repo... » read more

Issues And Options At 5nm


While the foundries are ramping up their processes for the 16nm/14nm node, vendors are also busy developing technologies for 10nm and beyond. In fact, chipmakers are finalizing their 10nm process offerings, but they are still weighing the technology options for 7nm. And if that isn’t enough, IC makers are beginning to look at the options at 5nm and beyond. Today, chipmakers can see a p... » read more

Thermal Is Still Simmering


With the ever increasing sophistication in today’s high-performance [getkc id="81" kc_name="SoC"]s on top of sheer physics of device manufacturing, thermal is a much bigger concern than ever before. It is well understood that thermal and power are closely related, and there exists a vicious cycle between leakage power and temperature: leakage goes up, temperature goes up; temperature goes ... » read more

The Interconnected Web Of Power


Tradeoffs between area and timing used to follow fairly simple rules. You could improve timing by adding area, and occasionally find an architectural solution that would decrease both at the same time. With physical synthesis the relationship became a little more complicated because an increase in area, say to make a drive larger or add another buffer, might upset the layout. That, in turn, cou... » read more

Partition Lines Growing Fuzzy


For as long as most semiconductor engineers can remember, chips with discrete functions started out on a printed circuit board, progressed into chip sets when it made sense and eventually were integrated onto the same die. The primary motivations behind this trend were performance and cost—shorter distance, fewer mask layers, less silicon. But this equation has been changing over the past ... » read more

One-On-One: Dave Hemker


Semiconductor Engineering sat down to discuss process technology, transistor trends and other topics with Dave Hemker, senior vice president and chief technology officer at [getentity id="22820" comment="LAM Research"]. SE: On the technology front, the IC industry is undergoing some new and dramatic changes. What are some of those changes? Hemker: We focus on what we call the inflections.... » read more

Low Power Trends Toward FinFET


My previous blog, Power Reduction Techniques, covered which low power techniques were applicable for various process nodes, from larger planar CMOS process technologies through finFET. The 16 and 14nm finFET-based process nodes are moving into production this year, and we are seeing many companies rapidly move their designs to finFET. In my last post, I noted some of the reasons why finFET is s... » read more

FD-SOI Meets The IoT


Silicon-on-insulator manufacturing technology has been discussed for many years. IBM has used the partially depleted variation of SOI in its server products, but the fully depleted version has yet to find widespread adoption outside of mil/aero and automotive markets. That may change soon as applications in the Internet of Things ramp, given the requirements for ultra low power and low cost.... » read more

Next Channel Materials?


Chipmakers are making a giant leap from planar transistors to [getkc id="185" kc_name="finFETs"]. Initially, [getentity id="22846" e_name="Intel"] moved into finFET production at 22nm and is now ramping up its second-generation finFETs at 14nm. And the other foundries will enter the finFET fray at 16nm/14nm. So what’s next? Chipmakers will likely extend the finFET architecture to both 10nm... » read more

Manufacturing And Packaging Changes For 2015


This year more than 26 people provided predictions for 2015. Most of these came from the EDA industry, so the results may be rather biased. However, ecosystems are coming closer together in many parts of the semiconductor food chain, meaning that the EDA companies often can see what is happening in dependent industries and in the system design houses. Thus their predictions may have already res... » read more
