Title: Epitaxial growth of semiconductor and semiconductor device
Inventor: MOCHIZUKI KAZUHIRO
IPC: H01L21/331
Filed: 1990-02-16
Abstract: PURPOSE:To restrain surface segregation phenomenon of atom at a low temperature and to enable high concentration and rapid change of concentration of atom by forming a layer after removal of one or more atomic layers from a surface after epitaxial growth of a semiconductor layer containing atom of surface segregation. CONSTITUTION:After epitaxial growth of a semiconductor layer containing atom of surface segregation, one or more atomic layers are removed from a surface. At this time, surface segregation atom which exists in a form of adatom on a surface is also removed simultaneously. Migration to a following layer which causes surface segregation of atom is eliminated by starting epitaxial growth again thereafter. Thereby, it is possible to carry out rapid concentration distribution of atom as designed, to reduce change of concentration distribution of atom from a designed value due to diffusion by carrying out epitaxial growth at a lower temperature than in a conventional technique and to improve atom concentration to a solid solubility limit as reevaporation can be neglected or reduced.

Title: Detection of etching end point
Inventor: OSHIMA HISAZUMI
IPC: H01L21/3065
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a method for accurately detecting an etching end point. SOLUTION: Exciting light is radiated onto an etching removal area of an oxide film formed on a silicon wafer 1, and an intensity of photoluminescence light generated at the area irradiated by the exciting light is detected. Incomplete bond on the surface of the silicon wafer 1 exposed by the etching are coupled with hydrogens contained in an etching solution 2, and an etching end point is detected based on a change in the intensity of the photoluminescence light generated by fully bonding chemical structure on the surface of the wafer 1. That is, since the intensity of the fluorescence light is largely varied depending on whether or not the surface of the wafer 1 is inactivated, the etching end point can be detected on the basis of the intensity variation.

Abstract: PURPOSE:To reduce the throughput of color information by a color image reproduction processing system by converting the binarized signal made binary an artificial half-tone processing means into a many-valued signal through the arithmetic averaging operation between the binary-coded signal and respective threshold values of a threshold value matrix, and then performing a color correcting process by color masking arithmetic operation. CONSTITUTION:The color separation signal 3 of an original color picture 1 scanned by a color scanner 2 is converted immediately by the artificial half-tone processing circuit 4 into the binarized color signal 5 in which respective colors are expressed by a 1-bit small-letter symbol (c,m,y). At the time of such binarizing, threshold value condition is supplied from a threshold value memory 40 to the artificial half-tone processing circuit 4. This binarized color signal 5 is stored in an image memory 7 through a transmission line 6 when necessary and then led to a color correcting circuit 8. The color correcting circuit 8 performs color corrective arithmetic operation for (c,m,y) on the basis of a binary color signal input x=c,m,y in consideration of the same threshold information in a threshold memory 80 with said binary coding condition and then outputs a color correction signal expressed as binary x'=c',m',y'.

IPC: H05K3/32
Filed: 1994-03-04
Abstract: PURPOSE:To realize a very reliable bonding method wherein a bonding at atomic level takes place at the joint surface of an electronic part with a board when they are bonded together. CONSTITUTION:Joint surfaces of a piezoelectric plate 1 as an electronic part and a board 2 are subjected to a mirror-finishing process so as to be set smaller than 10nm in surface roughness and cleaned.
