    摘要: A wafer level package includes an epoxy layer formed on an adhesive covered substrate during manufacturing for securing electrical components in place prior to being embedded in a molded material. An electrically conductive block is fixed in the epoxy layer. Vias are formed for accessing face up component contacts using a metalized layer on the surface of the molded material. After stripping the adhesive and substrate, the epoxy layer is penetrated to expose electrical contacts for face down components. An electrical connection is made between the face up and face down components using the block. Optionally, a dielectric layer covers the molded material and a second metalized layer placed on the dielectric layer to carry another electrical component embedded in a second dielectric layer covering the first dielectric layer. Thus a stacked component arrangement including multiple die and passive components is effectively fabricated into the wafer level package.
