Patent JP-H039567-A (JP)
Title: Mos semiconductor device
Inventor: TATEYAMA TAKESHI
IPC: H01L29/78
Filed: 1989-06-07
Abstract: PURPOSE:To inhibit the extension of a depletion layer to a drain region and to prevent the deterioration of characteristics, such as a punch through, a threshold value and the like, due to a high electric field by a method wherein the interface between a silicon substrate and a gate insulating film is formed into such a structure as it is extended into a channel region. CONSTITUTION:The central part of a channel region of a p-type silicon substrate 1 is made to oxidize by a local oxidation method to form a thick oxide film and when this oxide film is removed, a recessed part is formed in the channel part. Then, a thermal oxidation is performed to form a gate oxide film 2, a gate electrode 3 is formed thereon and an N-type impurity is ion-implanted or is made to perform a thermal diffusion using the electrode 3 as a mask to form n-type source and drain regions 4 and 5. In such a way, when the interface between the film 2 and the substrate 1 is formed into such a structure as it is extended into the channel region, the effect of inhibiting the extension of a depletion layer to the region 5 is generated and the generation of a punch through between a source and a drain is suppressed. In particular, in the case where the channel length is 2mum or below, the deterioration of characteristics, such as a punch through a threshold value and the like, due to a high electric field which is generated in the vicinity of the drain region can be prevented.

Title: Photoconductive cell
Inventor: YAMAMOTO HIROCHIKA
IPC: H01L31/08
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To absorb a light signal in a photoconductive layer, by sandwiching a photoconductive layer part with a pair of plate electrodes, and specifying the thickness of the photoconductive layer part to the optical signal absorption length. SOLUTION: Scratching process is performed on a high melting point metal which is to be a lower electrode 1 by using diamond powder. As the electrode, a high melting point metal, for example, platinum, that provides ohmic junction with diamond is used. Then, a polycrystalline diamond film 2 is grown on the electrode by CVD method. The polycrystalline diamond film 2 becomes photoconductive layer. As higher speed operation can be expected with the thinner photoconductive layer, the thickness of the photoconductive layer part is preferably approximately double the light signal absorption signal or more, not exceeding approximately 500 μm. Thus, almost all signals do not pass through and are absorbed in the photoconductive layer.
