WebGaAs device. Ł This GaAs HBT has a higher fT than these Si or SiGe devices and should provide more gain per stage. Ł– Ł It is difficult to determine which process is better suited for PA applications based on fitechnologyfl type arguments alone. These arguments tend to only consider one PA performance metric (without regard to any others). WebDec 1, 2015 · The GaAs pHEMT process under consideration in this paper is close to producing equivalent results from HAST and THB. In contrast, a HAST test with duration of only two hours would be equivalent to a thousand-hour THB test for the GaAs process studied by Ersland et al. [2]. This underlines the importance of process-specific moisture …

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. geisinger lewistown hospital lab
