Reference of 1806-29-7. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1806-29-7, Name is 2,2-Biphenol
Naphthoquinonediazidesulfonate ester, positive type photosensitive resin composition using the same, and semiconductor device or display device using the composition
[PROBLEM TO BE SOLVED]: To provide a positive type photosensitive resin composition with high sensitivity and high resolution having a characteristic that the film decrease is few and there is no crumble of pattern configuration, and in addition the photosensitive resin composition in the exposure part doesn’t have remain(scum). [SOLUTION]: The positive type photosensitive resin composition characterized by containing 100 weight part of alkali soluble resin (A) and 1-50 weight part of 1,2-naphthoquinone-2-diazide-5-sulfonate ester and/or 1,2-naphthoquinone-2-diazide-4-sulfonate ester of phenol compounds shown by general formula (1).
