发明名称 Thin quad flat package with no leads (QFN) fabrication methods
摘要 Embodiments of the present invention include a method of packaging semiconductor devices. The method comprises the steps of molding a surface of a wafer, sawing the wafer into individual devices, attaching the individual semiconductor device to an adhesive surface, molding the exposed surface, and sawing the wafer into individual semiconductor devices. The step of molding forms a continuous molded layer. The step of sawing results in each individual semiconductor having a molded layer. This molded layer corresponds to a portion of the continuous molded layer. The step of attaching includes attaching the molded layer of the individual semiconductor devices to the adhesive surface. The step of molding the exposed area includes molding an exposed area above the adhesive surface. This forms a solid expanse of material. The step of sawing the wafer into individual semiconductor devices includes sawing the solid expanse of material.
