Paper Abstract

An aqueous developable two layer resist system has been developed using a poly(dimethylglutarimide) (PMGI) based planarizing layer. This material offers better resistance to dry etching and thermally induced flow than PM M A. The PMGI layer is highly solvent resistant so no interfacial mixing with conventional positive resist top layers is observed. The pattern transfer exposure wavelengths for the PMGI are 240 - 280 nm. Dyes were added to the novolak based top layer to ensure optimum deep UV masking for thicknesses less than one micron.
