IPC: G02B6/00
Filed: 1983-06-03
Abstract: PURPOSE:To produce a photoconductive path having a three-dimensional pattern easily by forming a clad part prior to the polymerization and formation of arrays in a core part. CONSTITUTION:A substrate 2 is held by a supporting rod 3 under a photomask 1 having a circular or rectangular part preventing the transmission of light in its window and a vessel 4 is filled with a monomer mixture 5. When parallel ultraviolet light 6 is irradiated from the upper part of the vessel 4 and the substrate 2 is slowly lowered, the monomer on a part exposed through the window of the photomask 1 is photopolymerized and a polymer 8 having holes 7 is formed on the substrate 2 in accordance with the lowering of the substrate 2. If both the movement and replacement of the mask 1 are applied, an optional hole pattern is obtained. The substrate 2 is lowered by the supporting rod 3 coupled with a feeding mechanism interlocking with a motor. The polymer 8 polymerized up to necessary length and taken out from the mixture 5 is completely polymerized and resin having a refractive index higher than the polymer is injected into the holes 7 and hardened. Thus, the obtained polymer is removed from the substrate 2 and both the surfaces are polished.

Title: Formation of thin carbon film
Inventor: NAOE MASAHIKO
IPC: H01L21/314
Filed: 1988-04-20
Abstract: PURPOSE:To use a low-melting-point material for a substrate and to improve the adhesive property of a thin carbon film by impressing a positive bias voltage on a substrate on which a carbon film is to be formed in the sputtering method wherein a voltage is impressed on a target. CONSTITUTION:A negative voltage is impressed on targets 3 and 3 to sputter the targets 3 and 3, and a thin carbon film is formed on a substrate 6 at the side position facing a plasma space formed by the sputtering. In this case, a positive bias voltage is impressed on the substrate 6 by a power source 10. By this method the carbon particles in the plasma space are deposited on the surface of the substrate 6 to form a film. However, the sputtering gas ion is not allowed to collide with the positively charged surface of the thin carbon film, and the negatively charged gamma electron collides with the surface. Accordingly, the film quality is not deteriorated, and the thin film of high- hardness carbon having a high adhesive strength can be formed on a low- melting-point substrate since the thin carbon film is not heated to a high temp.
