Title: Structure and manufacture of semiconductor crystal layer
Inventor: KITAHARA KUNINORI
IPC: H01L29/812
Filed: 1988-02-24
Abstract: PURPOSE:To form a GaAs single crystal layer of low dislocation density by applying a buffer which is doped with high density impurity in addition to a conventional two-stage growth method when forming a semiconductor crystal layer of GaAs-on-Si structure. CONSTITUTION:A buffer layer which consists of a GaAs layer 5 doped with high density impurity is formed on an Si substrate 1 and a GaAs single crystal layer 3 of epitaxial growth is formed thereon. The impurity doped in the GaAs layer 5 is Si, for example, and the density is controlled within the range 1X10<18> a atom/cm<3> or 1X10<21>atom/cm<3>. Such constitution prevents mis-fit dislocation in GaAs-on-Si structure from propagating to a crystal surface when producing the GaAs buffer layer 5 instead of undoped GaAs buffer layer formed by a conventional two-stage growth method. In this way, a GaAs single crystal layer 3 of good crystallinity can be formed.

Title: Semiconductor light receiving element and its manufacture
Inventor: SUGIYAMA MITSUHIRO
IPC: H01L31/18
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce a leak current by a method wherein an impurity layer, having the impurity density higher than that of the other part of an epitaxial layer, is formed on a part of the side face of the epitaxial layer which comes in contact with an insulating film. SOLUTION: When inverted bias is applied to a P-N junction, a depletion layer spreads out on a P<-> silicon epitaxial layer 6 having low impurity density. At this time, as the impurity density of a P-type diffusion layer 7 is high by two figures, the depletion layer scarcely spreads on this region. As a photodiode, having a shallow light absorbing layer of about 1.0μm, is characteristically operated at low voltage, its application voltage is only 5V or thereabout, and the light absorbing layer 6, whose density is low at the above-mentioned voltage, is easily depleted, but a P-type diffusion layer 7 is not depleted. Accordingly, as an interfacial level does not come in the depletion layer, a leak current, which was allowed to flow on the interfacial level in the past, can be decreased.

IPC: A47B77/06
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To improve efficiency in cleaning work and to eliminate the scatter of water drops by providing the back guard side of a drainboard with a drain sink, which has depth narrower than a working space part just in a specified ratio, shallower than a sink. SOLUTION: A drain sink 6 is provided on the side of back guard 5 at the back of working space 4 on a work top 2, its size is made shallower than a sink 3 and further, its depth is made less than the 1/2 depth of working space part 4. It is necessary for the drain sink 6 to be provided on the back guard side of working space part 4, namely, closer to the back side so as not to occupy the front side to be most frequently used in the working space part 4 and the working space part 4 on the front side can be sufficiently secured. Since dish drainage can be performed in the drain sink 6 by the side of sink 3, a distance for moving wet tableware just washed in the sink 3 is shortened and cleaning work can be effectively performed. Further, the drops of water are not scattered around the sink 3 and the surrounding does not get water- soaked.
