Patent JP-H0371620-A (JP)
Title: Manufacture of compound semiconductor device
Inventor: KURAMATA AKITO
IPC: H01L31/10
Filed: 1989-08-10
Abstract: PURPOSE:To prevent occurrence of the crystal defects such as non-luminous recoupling center or luminous recoupling center and the like by a method wherein, after the first layer of second crystal has been grown in the first thickness at first speed on the first crystal, a second layer is grown at a higher speed. CONSTITUTION:When an InP layer 2 is grown in a vapor phase on InGaAs (P) crystal 1, the growth of the InP layer 2 in the first stage of growth is conducted at the speed slower than 4mum/hr or less, for example, and then the growth is conducted at a higher speed. As a result, the growth of non-luminous recrystallization can be prevented. Code 20 indicates the InP layer grown at a low speed, and code 21 indicates the InP layer grown at a high speed. As a result, a layer can be formed at a high speed without generation of the crystal defect which developes to non-luminous recrystallization center and luminous recrystallization center.
