Abstract: Esters of 1-oxo-2-diazo-naphthalene sulfonic acid wherein the sulfonic acid group is at either the 4 or the 5 position of a hydroxymethyl-tricyclo [5.2.1.0 ] decane wherein the hydroxy group is either at the 3 or 4 position and useful as sensitizers for positive resists, particularly relatively thick resists at 365 nm.

Abstract: The present invention is concerned with a method of converting a single resist layer into a multilayered resist. The upper portion of the single resist layer can be patternwise converted into a chemically different composition or structure having altered absorptivity toward radiation. The difference in radiation absorptivity within the patterned upper portion of the resist enables subsequent use of blanket irradiation of the resist surface to create differences in chemical solubility between areas having the altered absorptivity toward radiation and non-altered areas. The difference in chemical solubility enables wet development of the patterned resist.

Abstract: The invention relates to a lithographic resist composition for use in a method of forming a film (17) on a substrate (11) comprising the steps of providing a deposition mask (10) of the resist composition on the substrate (11), exposing a selected portion of the mask to ultra-violet rays, dissolving the exposed portion with aqueous alkali to form an aperture (15) with negative slope or overhang, depositing on said substrate (11) through the aperture (15) said film (17) and removing the deposition mask (10). The resist composition comprises a phenolic-aldehyde resin, a photosensitizer and Meldrum's diazo, or Meldrum's acid or suitable analogs thereof as a profile modifying agent. The profile modifying agents useful in the present invention have the formula: wherein R1 is C1 to C20 alkyl or aryl, R2 is H, C1 to C20 alkyl or aryl, or together R1 and R2 are cycloalkyl, A is N or H.
