Title: Photosensitive resist, pattern forming method and printed board
Inventor: WATABE MAKIO
IPC: G03F7/26
Filed: 1989-11-22
Abstract: PURPOSE:To prevent offset and halation, to increase resolution and to form a resist pattern having high strength as a film by incorporating a UV absorber lowering its absorbance in a UV region while absorbing UV. CONSTITUTION:A resist layer 4 contg. a bleachable UV absorber, lands 2 for through holes and a wiring pattern for a circuit are formed on the surface of a glass-epoxy resin substrate 1. The UV absorber contained in the photosensitive resist lowers its absorbance in a UV region while absorbing UV so as to prevent halation and offset. Since the quantity of UV for irradiation is not reduced by absorption in the UV absorber, the quantity of UV required to cure the resist is easily ensured and the curing reaction of the resist can be accelerated. Offset and halation can be prevented without deteriorating the physical properties of the resist film and a high accuracy resist pattern can simply be formed.
