发明名称 Packages for encapsulated semiconductor devices and method of making same
摘要 A semiconductor device package comprises a container having a base and side walls of an electrically insulating material. A semiconductor device chip is disposed on the base, and a lead frame extends through the side walls. At least one electrical conductor couples the lead frame to the chip. A first layer of an electrically insulating cured gel covers the chip and the lead frame, and a second layer of an electrically insulating cured gel covers at least the portion of the first layer that covers the chip, but does not extend to the side walls. In one embodiment, the second layer has the shape of a dome. In a preferred embodiment the gel comprises silicone. In another embodiment a third layer of conformal insulating material is disposed on the second layer and essentially fills the container. Also is described is a method of making the package for use with RFLDMOS chips.
