    Abstract: Techniques for covering open-cavity integrated-circuit packages in a batch process are disclosed. In an example method, a plurality of open-cavity packages are molded on a single batch leadframe or substrate, each open-cavity package comprising a floor and a plurality of walls arranged around the floor to form a cavity, each of said the walls having a bottom end adjoining said floor and having a top side opposite the bottom end. At least one semiconductor device is attached to the floor and within the cavity of each of the open-cavity packages, and a single flexible membrane is affixed to the top sides of the walls of the plurality of open-cavity packages, so as to substantially cover all of the cavities. The flexible membrane is then severed, between the packages.

    Abstract: A molded semiconductor package includes a substrate having opposing first and second main surfaces, a semiconductor die attached to the first main surface of the substrate, an adhesion adapter attached to the second main surface of the substrate or a surface of the semiconductor die facing away from the substrate, and a mold compound encapsulating the semiconductor die, the adhesion adapter and at least part of the substrate. The adhesion adapter is configured to adapt adhesion properties of the mold compound to adhesion properties of the substrate or semiconductor die to which the adhesion adapter is attached, such that the mold compound more strongly adheres to the adhesion adapter than directly to the substrate or semiconductor die to which the adhesion adapter is attached. The adhesion adapter has a surface feature which strengthens the adhesion between the adhesion adapter and the mold compound.

    Abstract: A pressure sensor package includes a lead and a semiconductor die spaced apart from the lead and including a terminal and a diaphragm disposed at a first side of the die. The die is configured to change an electrical parameter responsive to a pressure difference across the diaphragm. The package further includes an electrical conductor connecting the terminal to the lead, a molding compound encasing the electrical conductor, the die and part of the lead, a cavity in the molding compound exposing the diaphragm, and a sealing ring disposed on a side of the molding compound with the cavity. The sealing ring surrounds the cavity and has a lower elastic modulus than the molding compound. Alternatively, the sealing ring can be a ridge of the molding compound that protrudes from the side of the molding compound with the cavity and surrounds the cavity. A package manufacturing method is also provided.
