Patent number: 5234793Abstract: A photolithographic method for structure generation in bilayer processes is provided. Pursuant to the method, a dimensional reserve is produced in a top resist structure by chemical treatment with a bulging agent. The expansion preferably is performed by treatment with an aqueous solution. The expansion can be set such that the dimensional loss to be anticipated in further etchings of the bottom resist or, respectively, of the wafer is exactly compensated for.Type: GrantFiled: April 24, 1990Date of Patent: August 10, 1993Assignee: Siemens AktiengesellschaftInventors: Michael Sebald, Recai Sezi, Rainer Leuschner, Siegfried Birkle, Hellmut Ahne

Patent number: 5213941Abstract: This invention provides an improved negative-working or positive-working, single sheet color proofing method which can accurately reproduce images by using colored, photosensitive layers on substrates which are then overcoated with partially developable adhesive layers.
