Introduction

Jin An Lee is a notable inventor based in Kuri, South Korea. He has made significant contributions to the field of semiconductor packaging, holding 2 patents that showcase his innovative designs and solutions.

Latest Patents

One of his latest patents is titled "Nonexposed heat sink for semiconductor package." This invention discloses a semiconductor package featuring a fully encapsulated heat sink. The design includes a semiconductor chip mounted on the heat sink's surface, which is in an electrically insulative, thermally conductive connection with multiple leads. These leads extend from an overhanging first end to a second end outside the package body. A ring of double-sided adhesive tape secures the heat sink to the overhanging portion of the leads. This innovative heat sink design minimizes voids and damage during the encapsulation process while maintaining thermal performance comparable to conventional exposed heat sinks.

Another significant patent is "Leadframe for molded semiconductor package and semiconductor package made using the leadframe." This patent describes a leadframe that includes leads extending from a dam bar toward a central chip mounting region. A pseudo tie bar extends diagonally from three corners of the dam bar toward the chip mounting region, while a resin introduction slot is located at the remaining corner. The slot is wider than the space between adjacent leads, and the leads adjacent to the resin introduction slot increase in width as they extend toward the chip mounting region. This leadframe design is utilized to form a semiconductor package with a molded resin body, effectively minimizing voids and damage during the molding process.
