A clipped decoupled twin-carrier module for IC memory chips is disclosed which allows a very flat assembly, as no pins are required for connecting the two chip carriers. Fig. 1 shows a horizontal version of the twin-carrier module. Two chip carriers 1 are mounted back-to-back. A supply voltage decoupling capacitor 2 is clamped between the two chip carriers 1. The assembly is held together by clips 3 that are soldered to pads on carriers 1. Joint signals and the power input for both chips 4 are applied through clips 3. Carriers 1 are provided with a metallization (wiring) which is surrounded by a ring 5 holding cap 6 to hermetically seal the chips. The proposed module allows all known chip attachment techniques, such as wire bonding or C4 flip-chip solder connections.
