Please email for lead time
Item Number: GaAs/AlGaAs on GaAs(SEMI) 50D035C1-US

2" dia. wafer GaAs/AlGaAs EPI on GaAs undoped (Semi-insulating)(100) by MOCVD deposition

Substrate:

  • GaAs Orientation: (100)
  • Undoped, Semi-Insulating
  • wafer Size: 2" diameter
  • Resistivity:>1x10^7ohm.cm
  • One side Epi-ready polished, back side: etched
  • EPD:<1x10^4 /cm^2


EPI Film :

  • Layer 1: 1.0 um th, Lattice matched Al/Ga alloy layer of Al(0.25)Ga(0.75)As: (100)
  • (Top) Layer 2: 130 nm, n-type GaAs:Si[100], Nc: (0.1-1)x10^18 /cc [ Si as dopant ]
  • On the back side we can expect some deposits and we can't guarantee the same quality (roughness) as in the case of active layer surface.
