Title:
パターン形成用基材、ネガ型レジスト組成物、パターン形成方法、および半導体装置
Document Type and Number:
Japanese Patent JP4245172
Kind Code:
B2
Abstract:
With the tendency of reducing the size of semiconductor circuit patterns, edge roughness on a resist pattern is increased when pattern dimensions required are close to the size of the resist molecules. Provided is a technique for preventing degradation of the device performance and negative effects over the system performance caused by the phenomena. A photoresist compound is used, which is a molecule having functional groups that are chemically converted due to an action of an acid with reduced solubility in alkaline developer.
