A positive type photoresist resin film includes a support film and a thermosetting positive type photoresist resin layer laminated over the support film. The positive type photoresist resin layer contains alkali soluble resin, a diazide based photosensitive compound and a sensitivity enhancer. The support film has a surface roughness that inhibits the formation of defect structures such as fish eye. The invention overcomes process inefficiencies and defects cause by spin coating photoresist technologies.
