Wanted: Better ways to reward CEOs

Rising productivity can create prosperity for corporations and individuals. The impact of new technology in boosting productivity was a major contributor to the lengthy economic upturn of the 1990s, according to Alan Greenspan when he was Fed Chairman.

Emerging Technology


High interest in low-end printable electronics

Discussions of Moore’s Law usually focus on the fastest microprocessors and the highest memory densities.


Tap


Process monitoring methodology using in-line parametric test

Some of the device defects that are coming to the fore at advanced technology nodes are due to shrinking linewidths that cause greater interaction between device lines.


Fpd


Cutting LCD costs with alternative inkjet printing

An LCD is composed of a number of parts including backlights, polarizers, glass, liquid crystals, and color filters, each of which requires numerous unit processes to manufacture.


Materials


A carbon-restoring silylation process for low-k dielectric repair

Organo-silicate glass (OSG) based low-k dielectric materials are widely used to minimize resistance-times-capacitance (RC) delays in the BEOL interconnect for <90nm node logic devices.

Industry Forum


It’s harder to refute the benefits of DFM

As the semiconductor world moves toward 45nm geometries-with 32nm and 22nm processes on the horizon-relying on designers to follow recommended design rules in addition to the standard minimum rules is increasingly less effective for improving yield.


FEATURES

Gases Gas Handling


Hydrogen bromide cylinder gas ppb-level water vapor measurement

The measurement of trace water vapor in corrosive gases such as hydrogen bromide (HBr) used in semiconductor manufacturing is essential to maintain process consistency and maximize device yields.


Etch


Extending process flexibility for single-wafer wet etch

Despite the success of some dry-etching processes, wet etching remains a staple in semiconductor device fabrication, as well as in many other related technologies, such as MEMS and photovoltaics manufacturing.


Cover Article


Precision requirements for advanced HP logic implantation

Traditionally, an implant process is defined by the implant species’ atomic mass, energy, dose, and angular wafer positioning with respect to the projected beam direction (beamline axis).


Contamination Control


Controlling contaminants with enhanced gas leak detection

In semiconductor and optoelectronics manufacturing, many hazardous gases are used, such as pyrophoric silane (SiH4) for thin-film deposition, corrosive chlorine (Cl2) for dry-etching, and toxic arsine (AsH3) for ion implantation.


Materials


Tackling power/performance trade-offs with silicon channel engineering

Since its earliest days in the 1950s, the semiconductor industry has been dependent on silicon technology to meet the price, performance, power, and package demands that have enabled rapid advances in the electronics arena.


Resists


Photoresist production using automated in-line viscosity control

As the critical dimensions of semiconductor devices continue to get smaller, film thickness control in the photolithography process becomes increasingly important.
