LEAD FRAMELESS HERMETIC CIRCUIT PACKAGE |
摘要 |
A open cavity semiconductor chip package that is leadless and does not have a metal lead frame as in conventional packages. The absence of a lead frame minimizes leakage paths and allows the novel package to be more readily fabricated as a hermetic package. A dual sided insulative or dielectric film is employed as the base interconnect between a semiconductor chip and outside contacts. Electrical connection from the top side of the film to the bottom side of the film is made through conductive micro-vias. The semiconductor chip is mounted on a paddle in a central opening in the film and wire bonded to pads on the film. After mounting of the chip, a cover or lid is attached to the film to encapsulate the assembly and maintain hermeticity of the package. |
