发明名称 Chip carriers with enhanced wire bondability
摘要 A substrate that is substantially non-wettable to adhesive resin is disclosed. The substrate is coated with a fluorinated silane composition. Preferable fluorosilane compositions include perfluoroalkyl alkylsilanes of Formula III:wherein R5 is a perfluoroalkyl alkyl radical; R6 is alkyl or alkenyl; X is acetoxy, halogen or alkoxy; n is 1 or 2; and m is 0 or 1. The composition is preferably applied in solution and upon evaporation of the solvent, forms a durable, non-wetting, yet well-adhering surface. In a preferred embodiment, the substrate is a chip carrier with enhanced wire bondability for use in the manufacture of a semiconductor device.
