Title: Polypropylene container
Inventor: TAKAHASHI YOSHINORI

Title: Semiconductor device, manufacture thereof and laser device
Inventor: MOCHIZUKI KAZUHIRO
IPC: H01S5/00
Filed: 1989-08-25
Abstract: PURPOSE:To suppress the shifting of impurity atoms by a method wherein a single crystal substrate is formed in such a manner that it has the surface which is inclined at the desired angle from a low exponential surface. CONSTITUTION:In addition to surface segregation, thermal diffusion is considered in the moving mechanism while impurity atoms are being epitaxially grown. The thermal diffusion has no off-angle dependency on a substrate. For example, in the case of Be-doped Al0.3Ga0.7As grown on a GaAs substrate 1 having the surface inclined in [011] direction from (100) face 2, the amount of movement to the surface side of Be is determined by surface segregation and thermal diffusion. As an off-angle becomes larger, the amount of movement of Be due to surface segregation is decreased, and the amount of movement of Be by thermal diffusion is increased. Accordingly, the amount of movement of Be hardly decreases even the off-angle is made larger by about 10 degrees. Besides, as the impurity atoms to the substrate side are moved by thermal diffusion only, the substrate does not depend on off-angle.
