Latest Patents

One of Leonard Perham's latest patents is titled "Semiconductor device having programmable interconnect layers." This patent describes an integrated circuit structure that includes a base semiconductor structure and a programmable semiconductor structure. These components are fabricated separately and later joined to form the complete integrated circuit. The base semiconductor structure contains conventional semiconductor devices made according to a first set of design rules. In contrast, the programmable semiconductor structure includes programmable elements fabricated according to a second set of design rules, which may differ from the first. These programmable elements are essential for controlling the configuration of the integrated circuit or providing field-programmable devices.

Another significant patent by Perham is "Reduction of topside movement during temperature cycles." This patent presents an integrated circuit structure featuring a patterned uppermost conductive layer with a current-carrying trace. The trace connects to an underlying substrate through a multi-layer interconnect structure. Notably, the current-carrying trace, located around the outer edges of the integrated circuit, exhibits a serpentine pattern. A topside film is placed over the patterned layer, with increased thickness near the serpentine pattern. This design enhances the strength of the topside film structure, protecting inner traces from excessive forces during thermal cycling.
