Patent ID: 8318407

Claim:
A method for making a device, comprising: providing a thin film or laminate structure comprising a substrate, a first layer for patterning, and a second positive resist layer comprising a hafnium and/or zirconium oxy hydroxy sulfate (MO 2-x-z/2 (OH) z (SO 4 ) x ) compound, a hafnium and/or zirconium oxy hydroxy tungstate (MO 2-x-z/2 (OH) z (WO 4 ) x ) compound, a hafnium and/or zirconium oxy hydroxy borate (MO 2-3x/2-z/2 (OH) z (BO 3 ) x ) compound, a hafnium and/or zirconium oxy hydroxy phosphate (MO 2-3x/2-z/2 (OH) z (PO 4 ) x ) compound, and/or a hafnium and/or zirconium oxy hydroxy silicate (MO 2-2x-z/2 (OH) z (SiO 4 ) x ) compound, where M is hafnium or zirconium, x and z may be fixed or variable, and have any value for x in a range of from about 0.1 to about 3.5/(polyatomic ion charge), and any value for z in a range of from 0.0 to about 3.8; exposing the structure to an energy source to convert resist layer material into a developer-soluble material; and removing the developer-soluble material by treating the developer-soluble material with a developer solution to form a desired pattern.
