Abstract

A method for making a flip chip in a leaded molded package is disclosed. In some embodiments, the method includes using a leadframe structure including a die attach region and leads. The die attach region includes depressions proximate the inner portions of the leads, and an aperture in the die attach region. A semiconductor die is mounted to the die attach region. A molding material passes through the aperture and covers the first surface of the semiconductor die and the die attach region.
