The degradation mechanism of a-SiN:H films under current injection is investigated. It is shown that the degradation of a-SiN:H films is closely related to the hole trapping into Si-Si, Si-H, and Si0 defects. It is presumably concluded that the hole

A 1.5 μm GaInAsP/InP buried‐heterostructure laser diode was fabricated by reactive ion etching using a mixture of ethane and hydrogen for the formation of mesa stripe. Blocking layers were regrown on the dry etched wafers by liquid phase epitaxy.

InP crystals were etched by reactive ion etching (RIE) with ethane and hydrogen (C2H6/H2). Etched crystals and gas species were characterized by photoluminescence and mass spectroscopic measurements. Evaporation of phosphorus is induced by hydrogen,

An open-tube Zn diffusion method using solid sources of Zn3P2 and InP has been developed and applied to the fabrication of InGaAsP/InP heterojunction bipolar transistors (HBTs). The diffusion depth was accurately controlled by the diffusion time. A s

A maximum DC current gain of 112000 was obtained by a double-layer base HBT with a thin base layer of 0.1 μm thickness. A breakdown voltage with a common-emmitter configuration was found to be 1.3 V, which is smaller than for conventional HBTs owing

Emission spectra of a tandem‐type GaAs single quantum well laser diode were investigated under pulsed operating conditions. By controlling the two injection current levels, we could force the device to operate not only at the lowest (n=1) quantized

Mixtures of ethane and hydrogen are used as etching gas in order to etch InP, InGaAs and GaAs in reactive ion etching. Smooth surfaces and excellent vertical sidewalls have been obtained by choosing the optimum etching parameters. Etch rates obtained

High-purity InGaAs epitaxial layers with an area of 15 × 30 mm 2 were grown by using a conventional leak-tight liquid phase epitaxial growth system without any special treatments. A room temperature electron mobility as high as 12000 cm 2 V -1 s -1
