发明名称 Semiconductor device with plastic material covering a semiconductor chip mounted on a substrate of the device
摘要 A plastic covered semiconductor device that enables to simplify the structure and fabrication to reduce the assembly cost of the device and to reduce the thickness or height of the device. This device contains a substrate having a first surface and a second surface opposite to the first surface, a semiconductor chip mounted on or over the first surface, lead fingers joined to the first surface, interconnecting conductors electrically interconnecting the semiconductor chip with the corresponding lead fingers, respectively, and a plastic covering material formed to cover the first surface. Each lead finger is made of an inner part bonded to the first surface of the substrate and an outer part protruding the covering material. The covering material confines the semiconductor chip, the interconnecting conductors and the inner parts of the lead fingers. The second surface of the substrate is exposed from the covering material. An edge of the covering material is substantially in accordance with an edge of the first surface. The substrate acts as a top or bottom of a package of the device.
