摘要: A semiconductor package device is disclosed. In one embodiment, attached by its active face to a lead-on-chip leadframe having leadfingers an integrated circuit. The circuit has polyimide coating on backside. An encapsulating material surrounds the and so that are exposed. backside of helps reduce cracking arising from mounting printed board relflow solder.
