Abstract:
The disclosed method for the formation of a transparent conductive carbon film solves the problems of high temperature processing and long processing times, which are issues in graphene film deposition by thermal CVD, and uses a crystalline carbon film formed at lower temperatures and in less time using a graphene film. The disclosed method is characterised in that: the substrate temperature is set to 500°C or less; the pressure is set to 50 Pa or less; and a transparent conductive carbon film is deposited on the substrate surface of a copper or aluminium thin film by a microwave surface-wave plasma CVD process under a gas atmosphere in which an oxidation inhibitor for inhibiting the oxidation of the substrate surface is added to a mixed gas comprising a carbon-containing gas and an inert gas as an additive gas.
Abstract:
A casting belt 86 is produced of stainless steel. On a casting surface 86a on which a dope 61 is cast, two points Pl and P2 arranged in the widthwise direction X of the casting belt 86 are determined, such that the length L between two points Pl and P2 may be 10 mm. When a depth between the top and the bottom of the surface is continuously measured along the line P1P2, a depth maximum DE is at most 40 micrometers. Thus even if the film production is made for a long time, it is prevented that austenite partially transforms to martensite. Therefore, the scratches and deformations extending in the length wise direction hardly occur.
Abstract:
PROBLEM TO BE SOLVED: To make controllable the electric conduction of a p-type and n-type, etc., of a thin-film diamond layer, by implanting the ions of impurity elements into the thin-film diamond layer having such a high quality that it emits ultraviolet rays at a room temperature by exciting it through the projection of an electron beam on it when specifying its thickness. SOLUTION: This diamond thin-film manufacturing apparatus 100 is an end-launch type microwave-CVD diamond synthesizing apparatus wherein a microwave is projected on a substrate 11 from the normal direction thereof. Further, the ions of impurity elements are implanted into a thin-film diamond layer formed on the substrate 11 which has such a high quality that it emits ultraviolet rays at a room temperature by exciting it through the projection of an electron beam on it when its thickness is made at least not larger than 200 nm, and its electric conduction is made controllable correspondingly to the impurity elements. Therefore, as its raw-material gas, the mixture gas comprising a methane gas of a carbon source and a hydrogen gas is used, and by exhausting the air of a reaction container 13 through a process pump during its synthetic process, the vacuous environment of the inside of the reaction container 13 is kept very clean to perform its plasma CVD on the substrate 11.
