Abstract

A method for packaging a semiconductor device (22) formed on a die (12) having opposing major surfaces includes pre-soldering the die (12) at wafer level using an electroplating process, wherein the die (12) has solder bumps disposed on each opposing major surface. The pre-soldered wafer (10) is then diced into pre-soldered dies. The die (12) is placed in a glass sleeve (45) and aligned with two bumpless lead assemblies (46, 48). The bumpless lead assemblies (46, 48) are solder bonded to the die (12) via a reflow process. The reflow process also partially melts the glass sleeve (45), thereby forming a hermetically sealed glass capsule (55) surrounding the semiconductor device (22).
