Its original application was to high-frequency silicon switching transistors and ultra-high-speed integrated circuits. In the early 1960's Lepselter1, 2 developed the techniques for fabricating a structure consisting of electroforming an array of thick, self-supporting gold patterns on a thin film Ti-Pt Au base, hence the name "beams", deposited on the surface of a silicon wafer . The excess semiconductor from under the beams was removed, thereby separating the individual devices and leaving them with self-supporting beam leads or internal chiplets cantilevered beyond the semiconductor. The contacts served as electrical leads in addition to also serving the purpose of structural support for the devices.
