Patent ID: 7208195

Claim:
A method for depositing a thin film, comprising: a) heating a solid state material having a chemical composition to a temperature above a boiling point of said material to form a vapor in an evaporation device, wherein said vapor is directed inside an evacuated process chamber having a pair of members; b) condensing said vapor onto a substrate in said evacuated process chamber to form a liquid phase deposit, said liquid phase deposit having said chemical composition of said solid state material, wherein a temperature of said substrate is lower than the condensation temperature of said vapor and wherein a temperature of said evaporation device exceeds a temperature of said substrate by at least 500° C.; c) cooling said liquid deposit to form a solid phase film, wherein a chemical composition of solid state film includes said chemical composition of said solid state material; and d) cyclically and adiabatically varying the volume of said evacuated process chamber by expanding and contracting said members relative one and the other thereby increasing and decreasing the volume of said evacuated process chamber to increase and decrease the density of said vapor as said members are contracted relative one and the other.
