Deep Uv Photoresist With Alkyl 2-Diazo-1-Ones As Solubility Modification Agents
Deep Uv Photoresist With Alkyl 2-Diazo-1-Ones As Solubility Modification Agents
US Patent:
4959293, Sep 25, 1990
Filed:
Oct 28, 1988
Appl. No.:
7/264335
Inventors:
George Schwartzkopf - Franklin Township, Somerset County NJ

Assignee:
J. T. Baker, Inc. - Phillipsburg NJ
International Classification:
G03F 7004, G03F 7022, G03C 154
US Classification:
430189
Abstract:
2-diazo-1-ones are useful deep UV photoresist solubility modification agents exhibiting improved photosensitivity allowing shorter deep UV exposure times to achieve the same extent of photoreaction as with prior art solubility modification agents. The 2-diazo-1-one solubility modification agents when used as photoactive solubility modification components in photoresist compositions permit the photoresist compositions to act as either positive or negative photoresist compositions depending upon the developer employed, namely, as a positive resist when a metal ion containing developer is employed and as a negative resist when a metal ion free developer is employed.
