摘要： Novel bisphenol carboxylic acid tertiary ester derivatives having two aromatic ether groups and an ester group which are all replaced by acid labile groups are provided. The derivatives are used as a dissolution inhibitor in a chemically amplified positive resist composition comprising an organic solvent, an alkali soluble resin, and a photo-acid generator. Since the dissolution inhibitor has a highly reactive acetal group as an acid labile group, its coupling-off rapidly takes place after exposure. The dissolution inhibitor itself is less alkali soluble and its acid decomposition product is a phenol derivative having a carboxylic acid group with high alkali solubility, leading to a high dissolution contrast.

摘要： Double patterns are formed by coating a first chemically amplified positive resist composition comprising an acid labile group-bearing resin and a photoacid generator and prebaking to form a resist film on a processable substrate, exposing the resist film to high-energy radiation, PEB, and developing with an alkaline developer to form a first positive resist pattern, treating the first resist pattern to be alkali soluble and solvent resistant, coating a second resist composition and prebaking to form a reversal film, and exposing the reversal film to high-energy radiation, PEB, and developing with an alkaline developer to form a second positive resist pattern. The last development step includes dissolving away the reversed first resist pattern and achieving reversal transfer.
