摘要:
A process for forming a deposition film on a substrate comprises introducing separately a precursor or activated species formed in a decomposition space (B) and activated species formed in a decomposition space (C), into the deposition space wherein the film is formed on the substrate.
摘要:
A method for forming a deposited film, which comprises introducing gaseous starting materials, containing group III and/or group V compound as the constituent element for formation of a deposited film and a gaseous halogenic oxidizing agent having the property of oxidation action on said starting materials into a reaction space to effect contact therebetween to thereby form a plural number of precursors containing precursors under excited state, and forming a deposited film of a substrate existing in a film-forming space with the use of at least one precursor of said precursors as the feeding source for the constituent element of the deposited film.

A method for forming a deposited film comprises introducing into a reaction space containing a substrate (a) a gaseous starting material for the formation of a deposited film, (b) a gaseous oxidizing agent, and optionally (c) a gaseous material containing a valence electron controller component; effecting chemical contact therebetween to form a plurality of precursors including precursors in an excited state; and forming a deposited film on the substrate with at least one of the precursors.
摘要:
A multilayer photoconductive material wherein at least two kinds of alloys selected from the group consisting of amorphous silicon or germanium alloys comprising silicon and/or germanium and at least one element selected from the group consisting of carbon, fluorine and hydrogen are alternately laminated, the kinds of alloys of the adjacent layers being different from each other and the total number of the layers being at least 6, which has exhibits a high response speed and can be easily controlled in sensitivity not only to long wavelength light but also to short wavelength light.
摘要:
A deposited film is formed by introducing a gaseous starting material, a gaseous halogenic oxidizing agent and at least one oxygen or nitrogen type oxidizing agent into a reaction space to form excited precursors and thereafter forming a deposited film on a substrate in a film forming space employing the excited precursors. If desired, a gaseous material containing a component for valence electron control can be added to the reaction space.
摘要:
A method for preparing a multi-layer structure film by forming a deposited film according to the chemical vapor depostion method comprises introducing a subjective starting material gas (A) which is the major flow rate component and an objective starting material gas (B) which is the minor flow rate component and hydrogen externally activated into a reaction space and controlling periodically the amount of said objective starting material gas (B) introduced to thereby form a deposited film with a multi-layer structure.
摘要:
A process for forming a deposited film comprises introducing into a film forming space housing a substrate therein an active species (A) formed by decomposition of a compound containing germanium and a halogen and an active species (B) formed from a chemical substance for film formation which is reactive with said active species (A) separately from each other, then providing them with discharge energy and thereby allowing both the species to react with each other thereby to form a deposited film on the substrate.
摘要:
A process for producing a photoconductive member comprises forming a photoconductive layer on a substrate for formation of a photoconductive layer by introducing starting substances for formation of a photoconductive layer under gaseous state into a deposition chamber maintained under a desired reduced pressure and exciting discharging under the gas atmosphere of said starting substances, characterized in that said starting substances are constituted of at least two compunds selected from the group consisting of the compounds of the formula:Si.sub.n H.sub.2n+2 (A)wherein n is a positive integer and the compounds of the formula:Si.sub.m H.sub.l X.sub.k (B)wherein m and k are positive integers, l is 0 or a positive integer, l+k=2m+2, and X represents a halogen atom, n and m being called "order number" hereinafter, and said starting substances to be introduced into said deposition chamber being controlled in amounts such that the proportion of the total of high order compounds is at least 1 vol. % based on the total of the minimum order compounds, the minimum order compound being one whose order number is the minimum among order numbers of said at least two compounds, the high order compound being one whose order number is higher than the order number of the minimum order compound.
