Abstract

Official abstract text for this publication.

There is provided a production method which enables stable formation of a p-type zinc oxide film and also is suitable for enlarging the area of the film. The method for producing a p-type zinc oxide film according to the present invention comprises the steps of: placing a target containing a zinc source and a substrate in a gas atmosphere containing a nitrogen source and an oxygen source and having a gas pressure of 0.1 Pa to 100 Pa, and exposing the target to arc discharge, thereby forming a precursor film containing zinc and oxygen on the substrate; and annealing the precursor film in an oxidizing atmosphere, thereby forming a p-type zinc oxide film.

First claim

Opening claim text (preview).

What is claimed is: 1 . A method for producing a p-type zinc oxide film, comprising the steps of: placing a target containing a zinc source and a substrate in a gas atmosphere containing a nitrogen source and an oxygen source and having a gas pressure of 0.1 Pa to 100 Pa, and exposing the target to arc discharge, thereby forming a precursor film containing zinc and oxygen on the substrate; and annealing the precursor film in an oxidizing atmosphere, thereby forming a p-type zinc oxide film. 2 . The method according to claim 1 , wherein the formation of the precursor film using the arc discharge is conducted using an arc plasma gun. 3 . The method according to claim 1 , wherein the target is a metal zinc target. 4 . The method according to claim 1 , wherein the gas containing a nitrogen source and an oxygen source is a gas mixture of N 2 and O 2 . 5 . The method according to claim 4 , wherein the gas mixture is atmospheric air. 6 . The method according to claim 1 , wherein the annealing is conducted at a temperature ranging from 200° C. to 700° C. 7 . The method according to claim 1 , wherein the oxidizing atmosphere is air atmosphere or O 2 atmosphere.
