Feature Products


Semicon West '99 Product Spotlight

The product spotlight is an exhibition of innovative equipment and tools to be presented at the show.


Cmp Processing With Low


CMP processing with low-k dielectrics

Migrating to low-k dielectrics for interconnects will dramatically alter CMP requirements, even when the new material is buried in a stack.


Lithography


Favored SCALPEL's continued progress

The industry has made significant moves toward commercializing scattering with angular limitation projection electron-beam lithography, one of International Sematech's next-generation lithography methods funded in 1999.


Simplified Interconnect


Simplified interconnect processing for cost-sensitive chips

The clever combination of several new process technologies allows for interconnect formation using one-third of the steps needed by conventional methods.


Front Page


Ozonated water for photoresist removal

Improvements in ozone generation and the use of additives that prevent early decomposition of ozone have facilitated ozonated DI water resist stripping and surface cleaning of metallized wafers


Feature


Choosing capillaries for fine pitch bonding

Software analysis enables optimization of wire-bonder capillary selection, leading to improved wire bond quality and stronger bonds, particular for <100um pad pitches or applications at reduced temperatures.


Feature


Cobalt silicide processing in a susceptor-based LP-RTP system

The process control achieved by a susceptor-based RTP tool improves the process window for cobalt silicide formation.


Deposition


Tailoring sputtered Cr films on large wafers

Two new approaches for sputter depostion of uniform low-stress chromium involve post-eposition film treatment by RF Plasma and a multistep process that alternates depostion and surface plasma and a multistep process that alternates deposition and surface plasma treatment.


Fab Management


The

Automated individual wafer tracking can eliminate misprocession and lower material costs by detection and correction wafer-handling errors, and can check test wafer contamination levels. Both processes provide manufacturing cost savings.


Industry Insights


A time for change in creating international standards

Appropriate standards are necessary to deliver products and services efficiently to a global market. While traditional standards bodies have served the industry well in the past, new mechanisms for setting some standards are being forged to keep pace with today's rapidly changing technology.


Vacuum Technology


Management of TEOS LPCVD process effluents

TEOS LPCVD processes tend to clog the vacuum pumping foreline with effluent byproducts that can increase particle levels, impede gas flow, and cause catastrophic pump failure.

Editorial


Editorial: SOCs will reshape the industry

Over its first half century, the semiconductor industry has gone through constant change. Now it is moving toward perhaps the most dramatic shift of all -- toward system-on-a chip (SOC).

Market Watch


Long-term outlook for MEMS: New applications and markets*

Although a majority of industry observers are predicting rapid growth in microelectromechanical systems (MEMS) sales over the next five years, well-established MEMS product lines - airbag accelerometers, automotive engine manifold absolute pressure sensors, blood pressure sensors, and thermal inkjet printer heads - are expected to grow only moderately, due to high levels of market penetration.
