WebNew positive-tone deep-UV photoresist based on poly(4-hydroxystyrene) and an acid labile protecting group p. 125 Quantitative analysis of chemically amplified negative photoresist using mirror-backed infrared reflection absorption spectroscopy p. 143 Characterization and modeling of a positive-acting chemically amplified resist p. 153 WebOne of the principle concerns in the design of deep-ultraviolet (DUV) photoresist systems is optimization of the optical absorbance of the resist at 248 nm. Conventional novolak resists absorb strongly (OD greater than 1/micrometer), and are therefore not useful in the DUV.
