Title: Semiconductor laser
Inventor: SUGAO SHIGEO
IPC: H01S5/00
Filed: 1990-02-01
Abstract: PURPOSE:To obtain a high quality semiconductor laser whose dislocation is decreased by specifying the longitudinal direction of a laser resonator and the shape of the junction part between a III-V compound semiconductor layer and a silicon single crystal substrate. CONSTITUTION:The junction part between a silicon single crystal substrate 10 and a III-V compound semiconductor layer forms a stripe shape having the width of 10mum or less has a stripe whose width is 10mum or less. The longitudinal direction of the stripe (in parallel with the length of a resonator) is inclined by 10 deg. or more within a plane {100} with respect to the direction of [011] of the silicon single crystal substrate 10. Thus, the length in the direction in parallel with the direction of [011] of the junction part becomes 100mum or less. Therefore, the high-quality compound semiconductor layer having less dislocation can be formed. As a result, the high-quality semiconductor laser having the low threhold value can be formed.

Title: Phosphor
Inventor: IWAMA KATSUAKI
IPC: H01J61/44
Filed: 1987-02-04
Abstract: PURPOSE:To provide a bluish green phosphor having an enhanced luminescence peak height and improved brightness, which comprises Eu<2+>-activated strontium aluminate and Gd2O3 dissolved therein in the form of a solid solution. CONSTITUTION:A bluish green phosphor of formula I comprising Eu<2+>-activated strontium aluminate and Gd2O3 dissolved therein in the form of a solid solution. A further improvement in the luminescence peak height can be attained when x and y are 6<=x<=8 and 0<y<=0.1 in the formula, respectively (e.g., a phosphor of formula II). In recent years, attention has been paid to a phosphor having a luminescence peak at 480-500nm, and a phosphor of formula III is known to the art. However, this phosphor is insufficient in the luminescence peak height. The phosphor of formula I prepd. by the dissolution of Gd2O3 in the form of a solid solution brings about an enhancement in the luminescence peak height and an improvement in brightness.

Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To improve the flatness of the surface of a semiconductor substrate to the order of atoms and enable the manufacture of a semiconductor device utilizing semiconductor crystal growth on atomic steps on the surface of the semiconductor substrate. SOLUTION: The method for surface treatment involves a different atom region forming process and an atomic step shifting process. In the different atom region forming process the surface of a semiconductor substrate 101 is irradiated with an electron beam 104 in an atmosphere where process gas 103 containing atoms different from those contained in the semiconductor substrate 101 is present. A surface excitation reaction is thereby caused to form different atom regions 105 containing different atoms in specified areas on the surface of the semiconductor substrate 101. In the atomic step shifting process, atomic steps 102 are shifted on the surface of the semiconductor substrate 101. During the atomic step shifting process, the movement of the atomic steps 102 is controlled by means of the different atom regions 105 to form the atomic steps 102 into a specified shape.

Abstract: PURPOSE:To improve overall quality of whole wiring metal layers by a method wherein impurity ions are implanted into 1st metal layer to reduce the grain size of the metal and then 2nd metal layer, which mainly contributes to electric conduction, is formed on the 1st layer and increase of the grain size of the 2nd metal layer is suppressed. CONSTITUTION:By ordinary ion implantation technology, for instance boron ions (B<+>) are implanted into the surface of 1st Al layer 5 to reduce the grain size of the surface layer of the Al layer 5 by destructing the grains in the surface layer. Then, by ordinary evaporation or sputtering, 2nd Al layer 7 which mainly contributes to electric conduction and is substantially thicker than the Al layer 5 is formed on the Al layer 5. At that time, the growing plane of the 2nd Al layer 7 is composed of the Al layer with small grain size. Then, by ordinary lithography technology, the wiring metal layers are patterned altogether to form an Al wiring 8 which has the thin 1st Al layer 5 as its lower layer and the thick 2nd Al layer 7 which mainly contributes to electric conduction as the upper layer.
