Abstract:
A semiconductor device package comprises a container including a base and sidewalls. The base is configured to support a semiconductor device chip, and a lead frame extends through at least one of the sidewalls. A portion of the lead frame within the sidewall has at least one aperture penetrating into the lead frame. The sidewall material extends into the aperture, thereby forming a strong interfacial bond that provides a low leakage, sidewall-lead-frame interface. The base has a reentrant feature that is positioned within the thickness of at least one of the sidewalls and engages the at least one sidewall, thereby forming a low leakage base-sidewalls interface. The top surface of the base has a groove that is positioned within the thickness of at least one of the sidewalls and engages the at least one sidewall, thereby enhancing the low leakage base-sidewall interface.
