The Week In Review: Manufacturing


Chipmakers The NAND market is in flux. Not long ago, troubled Toshiba put its memory unit on the block. Finally, the company has selected a group to buy its memory business. The consortium includes the Innovation Network Corp. of Japan, the Development Bank of Japan and Bain Capital. Rival SK Hynix is also part of the group. Others attempted to bid on the business, including Western Digita... » read more

CMOS Image Sensors (CIS): Past, Present & Future


Over the last decade, CMOS Image Sensor (CIS) technology has made impressive progress. Image sensor performance has dramatically improved over the years, and CIS technology has enjoyed great commercial success since the introduction of mobile phones using onboard cameras. Many people, including scientists and marketing specialists, predicted 15 years earlier that CMOS image sensors were going t... » read more

The Week In Review: Manufacturing


Chipmakers Samsung has formed a new foundry division and rolled out a range of new processes. Specifically, Samsung plans to develop 8nm, 7nm, 6nm, 5nm and 4nm. It also introduced an 18nm FD-SOI technology. GlobalFoundries has provided more details about its 300mm fab plans in China. The company and the Chengdu municipality have announced an investment to develop an ecosystem for its 22nm ... » read more

Reworking Established Nodes


New technology markets and a flattening in smartphone growth has sparked a resurgence in older technology processes. For many of these up-and-coming applications, there is no compelling reason to migrate to the latest process node, and equipment companies and fabs are rushing to fill the void. As with all electronic devices, the focus is on cost-cutting. But because these markets are likely ... » read more

The Race To 10/7nm


Amid the ongoing ramp of 16/14nm processes in the market, the industry is now gearing up for the next nodes. In fact, GlobalFoundries, Intel, Samsung and TSMC are racing each other to ship 10nm and/or 7nm technologies. The current iterations of 10nm and 7nm technologies are scaled versions of today’s 16nm/14nm finFETs with traditional copper interconnects, high-k/metal-gate and low-k diele... » read more

What Drives SADP BEOL Variability?


Until EUV lithography becomes a reality, multiple patterning technologies such as triple litho-etch (LELELE), self-aligned double patterning (SADP), and self-aligned quadruple patterning (SAQP) are being used to meet the stringent patterning demands of advanced back-end-of-line (BEOL) technologies. For the 7nm technology node, patterning requirements include a metal pitch of 40nm or less. This ... » read more

The Week In Review: IoT


Conferences The Internet of Things World conference is on tap next week at the Santa Clara Convention Center in Silicon Valley. There will be more than 250 exhibitors on the show floor, with 11,000 attendees expected. More than 400 speakers will make presentations over three days, May 16-17-18. ON Semiconductor will have a number of IoT-related products to demonstrate at its booth, including i... » read more

Inside Lithography And Masks


Semiconductor Engineering sat down to discuss lithography and photomask technologies with Gregory McIntyre, director of the Advanced Patterning Department at [getentity id="22217" comment="IMEC"]; Harry Levinson, senior fellow and senior director of technology research at [getentity id="22819" comment="GlobalFoundries"]; David Fried, chief technology officer at [getentity id="22210" e_name="Cov... » read more

Photoresist Shape In 3D


Things were easy for integrators when the pattern they had on the mask ended up being the pattern they wanted on the chip. Multi-patterning schemes such as Self-Aligned Double Patterning (SADP) and Self-Aligned Quadruple Patterning (SAQP) have changed that dramatically. Now, what you have on the mask determines only a part of what you will get at the end. You will only obtain your final product... » read more

Understanding How Small Variations In Photoresist Shape Significantly Impact Multi-Patterning Yield


Multi-patterning schemes such as Self-Aligned Double Patterning (SADP) and Self-Aligned Quadruple Patterning (SAQP) have been used to successfully increase semiconductor device density, circumventing prior physical limits in pattern density. However, the number of processing steps needed in these patterning schemes can make it difficult to directly translate a lithographic mask pattern to a fin... » read more
