A customizable interconnect circuit wherein a universal substrate of minimum layers is completely customized by programmable conductive links placed only on the top layer of the substrate. The customizable circuit having high density of orthogonally placed X- and Y-conductors capable of interconnecting closely spaced large-scale integrated circuits or discrete electrical components. By utilizing a plurality of interconnect cells regularly spaced throughout a universal, fixed substrate, interconnect routing from overlying electrical components or integrated circuits can be more directly routed to target areas.

Base for a stool

A customizable circuit using a programmable interconnect and a compatible tape design for tape automated bonding of chips to the circuitry. The programmable interconnect comprises layers of wires, with one layer of wires forming overlap regions with the adjacent layer of wires. The wires can be selectively linked later to form the desired interconnect. The selective linkage represents the customization of an otherwise undedicated interconnect. The TAB chip bonding design uses a carrier tape to bond the integrated circuit chips to the programmable interconnect. Also disclosed is a method for forming the interconnect.

Customizable circuitry

An electrical beam switch for interconnection between a plurality of inputs and outputs and includes a two-dimensional array of electrically charged particle emitters and an array of detectors facing the emitter array for receiving charged particles from various of the emitters. X and y electrical deflectors are positioned adjacent each of the emitters for directing the charged particles from each of the emitters to a selected one or more of the detectors. A screen lens may be positioned adjacent the array of detectors for focusing the directed beams on to the selected detector.

Tennis training shoe

A high density electrical interconnect having a plurality of metallic conductors supported from metallic pillars which are electrically isolated from the ground plane by openings. The interconnect can be fabricated using a temporary support dielectric, which may be removed after completion to provide an air dielectric or be replaced with a more suitable permanent dielectric. The removal of the temporary support allows the conductors to be coated with protective layers or with a layer of a higher conductivity.

Method of fabricating a high density electrical interconnect

A thin film capacitor having a top, middle and bottom plate forming two capacitors in series in which the middle plate is a plurality of isolated plates thereby forming a structure of a plurality of two capacitors in series which are all connected in parallel. The capacitor may be integrated into an electronic substrate. The capacitor may be formed by depositing films of the metal conductors and dielectrics and may be formed as an integral part of a semiconductor chip or interconnect substrate.
