Abstract: A method of manufacturing a semiconductor device is provided. The method includes attaching a first die pad of a semiconductor die to a central pad of a package leadframe. The first die pad is located in a central region on an active side of the semiconductor die. A second die pad of the semiconductor die is connected a lead of the package lead frame. The second die pad is located in a periphery region on the active side of the semiconductor die. An encapsulant encapsulates a portion of the semiconductor die and a portion of the package leadframe. A backside surface of the semiconductor die is exposed at a top major surface of the encapsulant, and a backside surface of the central pad exposed at a bottom major surface of the encapsulant.

Abstract: A waterproof and breathable lining structure includes a sheet-like waterproof and breathable foaming cushion layer made of a composition of a predetermined amount of low density polyethylene (LDPE) and a predetermined amount of foaming agent such as azodicarbonamide (ADCA), and a fabric lining layer integrally adhered to one side of the cushion layer to form the lining structure. The cushion layer is made by a process including the steps of: (a) palletizing raw materials including the low density polyethylene and the foaming agent such as Azodicarbonamide (ADCA); (b) extruding the palletized raw material to make a solid sheet; (c) cross-linking the solid sheet by an E-beam to form an irradiated matrix; (d) foaming the irradiated matrix into the sheet-like foaming cushion layer.
