Abstract:
Thin-film microflex twisted-wire pair and other connectors are disclosed. Semiconductor packages include microflex technology that electrically connects at least one chip to another level of packaging. Microflex connectors, such as thin-film twisted-wire pair connectors according to the present invention provide superior electrical performance, which includes reduced line inductance, incorporation of integrated passive components, and attachment of discrete passive and active components to the microflex. All of these features enable operation of the chip at increased frequencies.

Through-chip conductors for low inductance chip-to-chip integration and off-chip connections in a semiconductor package is disclosed. A semiconductor device has active devices on the front surface, a first through-chip conductor having first electrical/physical characteristics passing from the front surface of the device to the back surface, a second through-chip conductor having second electrical/physical characteristics passing to the back surface, and an off-chip or chip-to-chip connector electrically connecting the active devices on the front surface to a different level of packaging.

Abstract:
PROBLEM TO BE SOLVED: To provide a semiconductor equipped having a dielectric layer of two-dimensional thickness, and to provide a method of manufacturing the same. SOLUTION: This manufacturing method comprises a first process of forming a mask with a through-hole 20 equipped with a side wall 21 on a structure (a), a second process of implanting suppression chemical seeds 24 into the structure through the through-hole 20 so as to form a suppression region 26 in the structure (b), and a third process of enabling a dielectric layer 28 to grow on the structure in the through-hole 20. Here, the suppression region 26 restrains the dielectric layer 28 partially from growing. By this setup, a self-aligned MOSFET or an anti-fuse device having a low overlap capacitance and a low gate induction drain leakage (i.e., low electric field) can be formed.
Abstract:
PROBLEM TO BE SOLVED: To provide a technique of selectively removing a material, which is used at the time of forming an electronic module, constituted of a 'stack' of a plurality of chips, from a cut groove region (kerf region) related to the semiconductor chips. SOLUTION: This method includes a method of providing a wafer having a plurality of integrated circuit chips having a cut groove region 17 between them. Chip metallized films 15 and 16 exist in the region 17. The wafer is protected using a photolithographic process, and only the region 17 is exposed. Then, the wafer is etched, and the chip metallized films are removed from the region 17. Then the wafer is diced, and the chips are stacked to form a monolithic electronic module. The side surfaces of the module are treated to expose a transfer metallic film which extends to the side surfaces of the module. Thereby, the electrical connection of the transfer metallic film to the chips in the module is facilitated.
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.
