Classification: CPC G  H | IPC G  H

Claim 15:
16. A method of manufacturing a semiconductor device, comprising:
forming a metallic photoresist layer over a target layer to be patterned;
selectively exposing the metallic photoresist layer to actinic radiation to form a latent pattern; and
developing the latent pattern by applying a developer to the selectively exposed photoresist layer to form a pattern,
wherein the metallic photo resist layer includes one selected from the group consisting of an alloy including 47-49 atomic % of Sn and 51-53 atomic % of Sb, an alloy including 56-58 atomic % of Sn and 42-44 atomic % of Sb, an alloy including 9-16 atomic % of Sn and 84-91 atomic % of Ag, an alloy including 24-26 atomic % of Sn and 74-76 atomic % of Ag, an alloy including 48-52 atomic % of Sn and 48-52 atomic % of Te, an alloy including 9-16 atomic % of Sb and 84-91 atomic % of Ag, an alloy including 22-26 atomic % of Sb and 74-78 atomic % of Ag, an Ag—Sb—Sn alloy including 0.1-75 atomic % of Ag, and an alloy of Sn and In.
