RADIATION CROSS-LINKABLE POLYMER SYSTEM FOR APPLICATION AS PHOTORESIST AND DIELECTRIC FOR MICRO WIRING
To shorten the exposure time, a negative photoresist is provided which is suitable for leaving on a microelectronic device as dielectric because of its thermal and mechanical properties and which consists of 90 to 100% of a polyether polyacrylate having acrylic acid terminal groups and of up to 10%...

Zusammenfassung: | To shorten the exposure time, a negative photoresist is provided which is suitable for leaving on a microelectronic device as dielectric because of its thermal and mechanical properties and which consists of 90 to 100% of a polyether polyacrylate having acrylic acid terminal groups and of up to 10% of a chemically related polyfunctional compound acting as crosslinking promoter. The polymer system has high UV sensitivity, can be cured without additional heat treatment and, because of its electrical and mechanical properties, is particularly suitable for producing microwirings. |
