    Abstract: A fabrication method and resultant three-dimensional multichip package having a densely stacked array of semiconductor chips interconnected at least partially by means of a plurality of metallized trenches are disclosed. The fabrication method includes providing an integrated circuit chip (50) having high aspect ratio metallized trenches (62) therein extending from a first surface to a second surface (58) thereof. An etch stop layer is provided proximate the termination position of the metallized trenches with the semiconductor substrate (52). Next the integrated circuit device is affixed to a carrier (70) such that the surface of the supporting substrate is exposed and substrate is thinned from the integrated circuit device until exposing at least some of the plurality of metallized trenches therein. Electrical contact can thus be made to the active layer of the integrated circuit chip via the exposed metallized trenches (66). Specific details of the fabrication method and the resultant multichip package are set forth.

    Abstract: An improved bistable FET circuit is disclosed which employs a reduced number of device elements and occupies less space in an integrated circuit. The flip-flop circuit includes the FET device having its source connected to a first potential and a second FET device having its source also connected to the first potential. The first FET device has a gate electrode composed of a resistive material with the first side connected to the drain of the second FET device and the second side connected to a second potential. The second FET device has a gate electrode comprised of a resistive material with the first side connected to the drain of the first FET device and a second side connected to the second potential. In this manner, the resistive gate of the first device serves as the load for the second device and the resistive gate of the second device serves as the load for the first device. Application of this circuit to electrically programmable PLA's and to random access memories is disclosed.
