Patent ID: 8070476

Claim:
A thermal insulation stamper, comprising: a first metal layer having a fine pattern on an exposed surface; a heat insulating layer formed of a heat-resistant resin and overlying the first metal layer, the heat-resistant resin containing oxygen; an intermediate layer formed of an oxygen-active metal and overlying the heat insulating layer; a conductive coating overlying a top surface of the intermediate layer; and a second metal layer overlying the conductive coating, wherein the intermediate layer is a vapor deposited layer that is deposited through plasma treatment and which during deposition activates oxygen contained in the heat insulating layer to form an interfacial region between the heat insulating layer and the intermediate layer where the oxygen establishes a chemical bond with the oxygen-active metal, and wherein a concentration of oxygen decreases from the top surface of the intermediate layer toward the heat insulating layer, and increases within the interfacial region from the intermediate layer to the heat insulating layer.
