The screen printing has to correspond with the higher efficiency and micronization of IC or LSI. Now higher precision and density in screen printing are strictly required and the precision has to be even less than 100 micron meter which brought up the shift to photographic process in this field. But in view of mass production screen printing has such advantage that it will promise to take an important part among electronics
materials in future.
UV-curable resin has the properties of quick-drying, high productivity at low temperature, energy saving, space saving, solventless, non-polluting and low-stinking, and thus, UV-curing system has been widely used in the fields of printing inks, adhesives, paints and coating agents.
This study has been executed to phosphor micro-patterning used UV-curable resin.
The phosphor micro-patterning properties of this photoresist were investigated under irradiation of UV light low pressure mercury lamp. When the exposed photoresist film was developed by pure water developer, the resolution of this photoresist was about 50㎛.
