More Information
Summary:The present invention relates to a photoresist composition sensitive to radiation in the deep ultraviolet, particularly a positive working photoresist sensitive in the range of 100-200 nanometers(nm). The photoresist composition comprises a) a polymer that is insoluble in an aqueous alkaline solution and comprises at least one acid labile group, and furthermore where the polymer is essentially non-phenolic, b) a compound capable of producing an acid upon radiation, and c) an additive that reduces the effect of electrons and ions on the photoresist image.
