Information and translations of GAAS in the most comprehensive dictionary … WebFor a GaAs pHEMT, indium is added to improve mobility and form a quantum well. Indium wants to growth the lattice and the typical range for useful thicknesses would be 10-25% on GaAs. You can also do strain compensation with the Schottky or cap layer. The purist nerds of semiconductors often capitalize "PHEMT" as pHEMT.
WebJun 14, 2004 · A minimum D-mode pHEMT drain-to-gate breakdown voltage of 15 V was required for 1 μA/μm current levels but, to maintain such a breakdown voltage with excellent process latitude, a trade off with on-resistance, output power and gain was made. 10 A similar trade off was made for the E-mode pHEMT device. This results in two separate … WebAn extrinsic transconductance of 80.0/spl plusmn/0.2mS/mm was obtained. The large selectivity of GaAs over InGaP (/spl sim/100 times) leads to a simple, controllable and reproducible pHEMT process. 展开

In addition, the design of the CPPLL …
Webfrom that of industry-standard 6-inch GaAs PHEMT wafers. Some of our 6-inch GaAs tools failed to recognize the GaN notch due to wafer transparency and the different notch position. We also observed a substrate “leakage” (i.e., leaking photoresist through micropipes in the SiC substrates during lithography process) on some early wafers.
WebA selective gate recess process for Pseudomorphic HEMTs utilizing In0.5Ga0.5P as the etch-stop layer has been developed. This process employs conventional sulfuric acid etch chemistry to obtain 150:1 GaAs/In0.5Ga0.5P etch selectivity.
