Verfahren zur Gehaeusung von integrierten Schaltkreisen
Other Title
Encapsulating integrated circuits on semiconductor substrate - using semiconductor and support substrates, with through-contacts giving electrical conduction from front-side main surface to electric terminal faces.
Abstract
The support substrate (4) has a front- and a rear-side main surface, each containing electrical terminal faces (7,8). The front face (7) couples to rear face (8) via through-contacts (9). The front-side main surface of the semiconductor substrate (1) is aligned with the front-side main surface of the support substrate such that terminal faces to be coupled are opposite each other. The two front-side main surfaces are interconnected so as to render the mechanical connection between the semiconductor and support substrates electrically conductive between the respective terminal faces. Preferably the semiconductor substrate is a wafer with several integrated circuits. USE/ADVANTAGE - For chip size packages. No danger of yield reduction.
