Patent ID: 8232232

Claim:
An oxide target for laser vapor deposition, which is used when an oxide film is formed in a laser vapor deposition system, comprising: a fixed plate; an Ag-soldering layer bonded onto the fixed plate; an oxide-Ag mixed layer bonded onto the Ag-soldering layer; and an oxide layer bonded onto the oxide-Ag mixed layer, wherein Ag in the oxide-Ag mixed layer and the Ag-soldering layer has a heat resistance temperature as high as 900° C., and wherein by sintering the oxide-Ag mixed layer and the oxide layer for bonding, the oxide in the oxide-Ag mixed layer and the oxide layer are firmly sintered to each other, and concurrently to the sintering, by metal-bonding the Ag in the oxide-Ag mixed layer and the Ag-soldering layer, the oxide layer on the surface is firmly fixed on the body of the target, and wherein the oxide-Ag mixed layer has a ratio by volume of Ag in a range of from 5 to 20%.
