Abstract

Dry etching of InP material based on inductivity coupled plasma(ICP) was thoroughly studied, Cl 2/Ar/H 2 gas mixture was adopted, and the etching depth could reach 10 μm with a vertical and a smooth surface. The gas percentages of the total gas versus etching rate, and the applicable regions of Ni, SiO 2, and the combination of Ni and SiO 2 were studied, respectively. The regions of the effective etching rate and selectivity against Ni are 450~1200 nm/min and 175~190, respectively. The choosing and fabrication approaches adopted are highly suitable for any semiconductor material based on ICP system.
