Molded ring integrated circuit package

An integrated circuit package, comprising:

• a metal lead frame including a plurality of leads having first and second portions;
• an integrated circuit die having two opposed faces, a first face including active circuitry in a central area and a plurality of interconnect pads disposed about a perimeter, and a second face including a central portion and a perimeter portion;
• said active circuitry being electrically attached to said first portion of said plurality of leads by flip chip bonding between respective said interconnect pads and respective said lead first portion;
• plastic molding material formed over said interconnect pads, said integrated circuit die perimeter, said direct connections, said first portion of the plurality of leads, and said perimeter portion of the second face;
• and
• said plastic molding material formed so as to reveal said central area on said die first face and said central portion on said die second face.

An integrated circuit package, comprising:

• a metal lead frame including a chip mounting portion having a window frame shape substantially forming a border of lead frame material around a central aperture, and a plurality of leads having first and second portions, said plurality of leads disposed in a pattern substantially around the chip mounting portion;
• an integrated circuit chip having two opposed faces, a first face including active circuitry in a central area and a plurality of wire bond pads disposed about a perimeter, and a second face including a central portion and a perimeter portion;
• said perimeter portion of said chip second face mounted upon said chip mounting window frame portion, and said active circuitry being electrically attached to said first portion of said plurality of leads by wire between respective said wire bond pads and respective said lead first portion;
• plastic material transfer molded over said wire bond pads, said chip perimeter, said wire bonds, said first portion of the plurality of leads, said perimeter portion of the second face, and said chip mounting portion;
• said plastic material formed so as to provide a first opening to reveal said central area on said chip first face and a second opening to reveal said central portion on said chip second face;
• and
• a cover over said first opening and attached to said plastic material to provide physical protection to said revealed active circuitry.
