The CMP-MIC conference held in Santa Clara, CA, saw the introduction of 3M Laboratories` new slurry-free oxide planarization technique, and the long-awaited linear CMP polisher from Lam Research`s OnTrak subsidiary.
Tech News Significant role seen for selective epi and Si3N4 CMP
Selective epitaxial silicon-germanium deposition and Si3N4 CMP could be significant processes for 4-Gbit DRAM technology. These processes were used at NEC`s ULSI Device Development Lab in Kanagawa, Japan, to fabricate a contact pad structure characterized by large 70-nm (0.07-?m) alignment tolerances for both DRAM word line and isolation regions. The final structure is a 135-nm2 folded-bit-line memory cell in one of NEC`s 4-Gbit DRAM designs, using a 120-nm design rule (see figure).
Tech News Value added from backend drives assembly automation
Today`s semiconductor manufacturing backend is a linear extrapolation of technology in place for 25 years. C. Scott Kulicke, chairman and CEO of Kulicke & Soffa Industries, stated that it has been "predictable progress. We`ve worked hard because, obviously, it is more complex to build a quad flat pack than a dual in-line package. But, while today`s factories may be bigger and more efficient, most still run the same old way - discrete lots of a few hundred or a few thousand units carried from sta
Tech News Laser system personalizes 0.35-um gate array
A newly upgraded laser micromachining system provides rapid personalization of 0.35-?m gate array devices, with improvements of throughput and accuracy.
Tech News Two SEMI groups discuss 9-in. reticle carriers
As the maskmaking industry works to implement standards for the transition to 9-in. reticles, two SEMI task forces charged with designing carriers for the larger glass substrates have taken divergent paths on their box designs. The North American group is placing minienvironments at the core of its design, while the Japanese group is opting for optimized containers for specific functions. As a result, four very different carriers are now being proposed for adoption. "We`re working under differen
