Bis-o-nitrophenols derivatives and poly-o-hydroxyamides, polybenzoxazoles, materials, and microelectronic devices made therefrom |
摘要 |
Materials for dielectrics and/or buffer layers in microelectronics utilize polymers can be based on bis-o-nitrophenols. The bis-o-nitrophenols carry a tert-butoxycarbonyl group on at least one of the hydroxyl groups. The polybenzoxazoles prepared from these compounds have a lower dielectric constant than corresponding polymers which are prepared from bis-o-nitrophenols that do not have a tert-butoxycarbonyl group.
