Spectroscopy exposes trace-water contamination in process gases Oct 15, 2007
A highly sensitive optical technique known as cavity ring-down spectroscopy can reveal minute levels of water contamination in MOCVD process gases such as arsine and can demonstrate the true benefit of point-of-use purification, say Jun Feng and Mark Raynor from Matheson Tri-Gas and Yu Chen from Tiger Optics.
PHEMTs rise to wide-gap challenge Sep 19, 2007
New geometries and field plates have extended the operating voltage, power output and efficiency of GaAs PHEMTs to a level where they can compete with SiC and GaN-on-silicon devices, claim David Fanning, Edward Beam, Paul Saunier and Hua-Quen Tserng from TriQuint Semiconductor.
Vertical HVPE tool produces 2 inch GaN Sep 19, 2007
Aixtron is helping to accelerate the commercialization of free-standing GaN through the launch of a vertical HVPE tool that features a hanging seed holder and is capable of producing 2 inch diameter boules, says Bernd Schineller.
Palladium barrier cuts materials bill Sep 19, 2007
If you develop the right process, a switch from a platinum to a palladium barrier can cut your PHEMT production costs without compromising leakage currents, says Skyworks' Kezia Cheng.
