Inventor: SENBA SHINJI
IPC: H01L31/10
Filed: 1989-10-31
Abstract: PURPOSE:To enable diffused mask layers imposing no strain at high temperature to be formed continuously by a method wherein semiconductor layers in smaller difference in thermal expansion coefficient, equal lattice constant and relatively smaller diffusion coefficient of impurity than those of a semiconductor to be diffused are continuously formed on the semiconductor. CONSTITUTION:A window W is made by lithography in an n<->-InGaAs mask layer 6a as a diffusion mask layer so as to diffuse Zn from this window W. At this time, an n<->-InP window layer 3 is in thickness of about 2-3mum in a semiconductor layer to be diffused. Since the Zn diffusion in an InGaAs layer is smaller than that in an InP layer by about 1/2-1/3, the n<->-InGaAs mask layer 6a can be used as a mask by specifying the thickness thereof to exceed three times of the thickness of the n<->-InP window layer 3. Furthermore, the InGaAs layer can be lattice-matched with the InP layer while the difference in thermal expansion coefficient between them is also relatively small.
