SEMICONDUCTOR DEVICES AND PROCESSES
This description relates generally to semiconductor devices and processes. A method for forming a packaged semiconductor package can include attaching a front side of a metal layer to a die pad of a leadframe that includes conductive terminals, so a periphery portion of the metal layer extends beyond a periphery pad surface of the die pad, and a portion of a half-etched cavity on the front side of the metal layer is located near the periphery pad surface of the die pad. The method further includes attaching a semiconductor device to the die pad and encapsulating the semiconductor device, the front side of the metal layer, a portion of a back side of the metal layer, and a portion of the conductive terminals to form a packaged semiconductor device.

SEMICONDUCTOR DEVICE MANUFACTURING METHOD
A semiconductor device manufacturing method includes a molding step including disposing a control pin between an inlet and a control wire and on a line connecting the inlet and the control wire in a plan view of the semiconductor device, injecting molding resin raw material into a cavity through the inlet, filling the cavity with the molding resin raw material, and sealing a semiconductor chip and a control element disposed on a main current lead frame and a control lead frame.

MOLDING DEVICE WITH SELF-BLOCKING FEED CHANNEL
A molding device for producing a molded module. The molding device has one tool part and one further tool part, which together enclose a cavity. At least one of the tool parts has at least one dividing web arranged and configured to subdivide the cavity into at least a low-pressure sub-cavity and a high-pressure sub-cavity. The tool part has at least two feed channels, of which a low-pressure feed channel opens into the low-pressure sub-cavity and has a smaller cross-section at least over a longitudinal portion than a high-pressure feed channel opening into the high-pressure sub-cavity. The low-pressure feed channel is configured to become pressure-resistantly blocked through hardening of the molding compound once a predetermined time interval has elapsed or during the interval. The high-pressure feed channel is configured to conduct a molding pressure into the cavity for a longer time interval than the low-pressure feed channel.
