| 摘要 |
A semiconductor package for mounting a chip is disclosed. The package includes a first metal or metal alloy component having a first thin refractory oxide layer on a first surface. The chip is bonded to the first component. A skirt extends from the first component for strengthening the first component and providing heat transfer from the semiconductor package. A second metal or metal alloy lead frame having second and third refractory oxide layers on opposite surfaces is electrically connected to the chip and is bonded to the first oxide layer. Also, the lead frame is insulated from the first component by the first and second refractory oxide layers. A second metal or metal alloy component has a fourth refractory oxide layer on one surface and is bonded to the third refractory oxide layer so that the chip is hermetically sealed between the first and second components. Other embodiments of the present invention include both leadless and leaded hermetic semiconductor packages and innovative relationships between the packages and printed circuit boards. |
