PAM XIAMEN offers PbTe single crystal substrate.(Not sell it temporarily) Lead telluride (Phoebe) is a compound of lead and tellurium (PbTe); it is a narrow gap semiconductor. It occurs naturally as the mineral altaite. It is often alloyed with tin to make lead tin telluride, [...]
PAM XIAMEN offers YAG( undoped ,Ce-doped,Nd-doped). YAG (undoped) Undoped YAG is a substrate material that can be used for UV and IR optics. Sapphire has been the substrate of choice for these applications; however it is difficult to polish Sapphire to a 10-5 scratch-dig [...]
InGaAs HEMTs form two-stage gain blocks delivering 9 dB of gain while consuming just 20 mW A TEAM of Taiwanese engineers has used flip-chip packaging to build anInGaAs HEMT delivering up to 6.5 dB of gain at 60 GHz. The researchers argue that one of the [...]
PAM XIAMEN offers4″ Silicon EPI Wafer-6 4″ Si epi wafer Structure: (Top layer intrinsic Si / Middle layer Phosphorus Doped / Ion Implantation / Si substrate) Top layer intrinsic Si: Resistivity≥50Ωcm, Thickness 5μm, Residual carrier concentration<1×1014/cm3 Middle layer Phosphorus Doped: Resistivity around 0.025Ωcm (Phosphorous concentration 7×017/cm3), Thickness 20μm, Residual carrier concentration<2.1×1013/cm3 Layer with Ion Implantation: handled [...]
PAM XIAMEN offers 2″ silicon wafers Thickness:1000 ±25μm. 2’’ silicon wafers Ra < 4 nm (100) Thickness1000 ±25μm Doped (no requirement for resistivity and type, resistivity and type will be shown on test report when shipment) 2 sides polished With flat (SEMI STD) For [...]
The dependence of the morphology and crystallinity of an amorphous Ge (a-Ge) interlayer between two Si wafers on the annealing temperature is identified to understand the bubble evolution mechanism. The effect of a-Ge layer thickness on the bubble density and size at different annealing [...]
