“Make in India”


By Bettina Weiss In recent weeks, I have been talking to SEMI members and other stakeholders about India. Some consider any semiconductor industry development in the country a dream. Others are looking more closely at current indicators of something real and tangible, trying to determine whether to get involved. The electronics sector in India will have to satisfy a huge demand growth... » read more

Capacity Constraints And DFM At Mature Nodes


We’re witnessing an interesting phenomenon in the SoC segment of the semiconductor industry today. One might call it the “forced waterfall effect.” What I’m referring to is the tendency for production at semiconductor nodes older than the leading edge to be under long-term foundry capacity constraints. Normally this occurs with the “hot process node,” that is, the leading edge wh... » read more

LIFT Your 3D Printing Application


A major focus at Photonics West 2015 was 3D additive manufacturing. There were sessions on laser additive processing, digital light fabrication, and MOEMS devices. In all sessions, there were papers about systems, materials processing and applications. Here are a few of the papers that caught my attention. Two photon fabrication was the most commonly reported technique, it is the only way to... » read more

Extra! Extra! Read All About It!


ASML announced that they are going into the pellicle business at 2:15pm on February 25 at the SPIE Advanced Lithography Symposium in San Jose. These are not your garden variety plastic membrane pellicles, mind you, but rather EUV pellicles made out of 50nm thick polysilicon film and stretched on frames that can be attached, removed and reattached on EUV masks. Dr. Carmen Zoldesi of ASML reveal... » read more

GaN Manufacturing Meets Big Silicon


I have been talking about GaN on Silicon for several years because it offers a path to cost reduction in LED’s in the same way as silicon semiconductors. This year at Photonics West 2015, Aixtron presented its next generation 6-inch wafer system with all the automation that the semiconductor guys expect to be able to build GaN power transistors. The systems are configured as cluster tools... » read more

The Power Of Collaboration: Solutions For Improving Manufacturing


The Fab Owners Association (FOA) held its third annual Collaborative Forum in Santa Clara, Calif., earlier this month. The focus of this event was to discuss how companies are able to work together to improve manufacturing efficiencies in wafer fabs. The forum is by invite only to FOA members, and I was invited to make a presentation on the market trends due to the impact of MEMS and Sensors. ... » read more

Searching For Rare Earths Again


Rare earths are back in the spotlight again. Rare earths are chemical elements found in the Earth’s crust. They are used in cars, consumer electronics, computers, communications, clean energy and defense systems. The big market for rare earths is magnets. In semiconductor production, rare earths are used in high-k dielectrics, CMP slurries and other applications. Last year, the World Tr... » read more

Balancing On The Color Density Tightrope


Balancing on wobbly tightropes is something that chip designers get pretty good at. For instance, there is a fine balance between optimizing performance and minimizing leakage in a design layout. Dealing with the new requirements that multi-patterning (MP) introduces into a design flow creates many new tightropes to walk. I tiptoed out on one of the rarely talked about ones in my last article�... » read more

Redefining Progress


After lots of wrangling over the whether Moore's Law is alive, dead, or languishing at somewhere in between, that discussion now seems about as relevant as the look and feel of Apple's early Macintosh operating system—an issue that back in the 1980s spawned a very public war with Microsoft. Today that argument is about as relevant as whether Betamax was better than VHS. Whether it's Moor... » read more

Rule Deck Comparison Doesn’t Have To Be Difficult


Foundry rule decks change all the time, as foundries uncover new manufacturing issues, or the process changes, or design criteria are tightened to improve runtime or stability. Sometimes new versions of a user’s design rule checking (DRC) tool are released, and the results from the DRC run differ from the previous version. Or perhaps a company wants to compare results between rule decks from ... » read more
