IPC: H01L21/822
Filed: 1988-07-19
Abstract: PURPOSE:To enable a resistance value to be controlled easily at a predetermined value by providing a high resistance body including an oxide film and an nitride film and controlling thickness thereof properly. CONSTITUTION:High resistance regions 63 and 64 are formed according to predetermined patterns such that contacts are defined directly on N<+>-type diffused regions 3 and such that they have a layered structure including at least an oxide film and an nitride film. Low-resistance polycrystalline silicon layers 51 and 52 are formed on these high resistance regions 63 and 64, respectively, so that the layers 51 and 52 have contacts with the high resistance regions 63 and 64, respectively. When current is supplied to the high resistance layer including the oxide and nitride films laid one on the other, tunnel current is conducted through the two-layer structure consisting of the nitride and oxide films. It is conducted hardly by the oxide film while it is conducted more easily by the nitride film than by the oxide film. Accordingly, the resistance value can be controlled easily by properly regulating thicknesses of the oxide and nitride films constituting the high resistance layer.

Filed: 1982-10-14
Abstract: PURPOSE:To form an optical waveguide having a high refractive index in a transparent substrate by manufacturing a substrate of a transparent gel having a projecting line by superposing partly a monomer forming a network polymer, and diffusing a monomer forming a polymer having the lower refractive index thereby polymerizing the same. CONSTITUTION:A monomer Ma forming network polymer Pa having a refractive index Na is partly superposed to manufacture a substrate 1 of a transparent gel. A projecting line 2 is formed on the substrate so as to correspond to the pattern for a prescribed optical waveguide on the one surface 1A side thereof in one body with the substrate 1. A monomer Mb forming a polymer Pb having the refractive index Nb smaller than the refractive index Na of the polymer Pa is diffused from the surface side formed with the line 2 into the substrate 1 and is thus polymerized. The diffusion penetration of the monomer is slower in the base part of the line 2 than in the part right under the plane part 1A and therefore an optical waveguide 3 having the refractive index distribution wherein the refractive index at the center is largest and decreases toward the periphery is formed.
