Title: Production of diamond
Inventor: YAMAZAKI OSAMU
IPC: C30B29/04
Filed: 1987-04-21
Abstract: PURPOSE:To form diamond with good reproducibility at high formation velocity by constituting also the surface of the necessary part of a substrate holder of carbon in a method for condensing carbon on the substrate while projecting high-speed particles to a carbonaceous target. CONSTITUTION:High-speed particles 4 of mixed ion beams of H2 and inert gas (Ar) are projected on a target 1 and a substrate 2 with prescribed energy e.g. by using an ion beam sputtering device. A graphite plate is used as the target 1 and sputtered and thereby carbon atom is flown out and condensed on the surface of the substrate 2 and a film is formed thereon. In this case, single Si crystal is used as the substrate 2 and a substrate holder 3 is obtained by working the graphite plate and allowed to coincide with the shape of the substrate 2 and dug only at its thickness to fix the substrate 2 therein. By this method, carbon is emitted by high-speed particles 4 allowed to collide against the holder 3 and contributes to the synthesis of diamond without becoming impurities. Therefore high-quality diamond can be synthesized with good reproducibility at high velocity.

IPC: H01L21/339
Filed: 1990-04-14
Abstract: PURPOSE:To reduce the capacitance of a floating diffusion layer and sensitivity for signal charge to be improved by making impurity concentration of an impurity layer at a lower surface or a part which is in contact with the lower surface and a side surface of the floating diffusion layer which converts signal charge into potential change. CONSTITUTION:A p-type impurity layer 2 is divided into two types of impurity layers, namely first and second p-type impurity layers 2a and 2b. An impurity layer surrounding a floating diffusion layer 9 out of these impurity layers, namely a second p-type impurity layer 2b, has a lower impurity concentration than that of other impurity layers, namely the first p-type impurity layer 2a. This condition enables a p-type impurity layer below the n-type floating diffusion layer 9 to be complete depletion layer and a depletion layer on a side surface of the floating diffusion layer 9 to be largely expanded, thus reducing the capacitance of the floating diffusion layer drastically. Therefore, potential change of the floating diffusion layer which is given by DELTAV=Q/C can be secured largely.
