Latest Patents

Kessler holds a patent for the "Incorporation of dielectric layers in a semiconductor." This innovative system integrates a composite dielectric layer in an integrated circuit. The design facilitates the fabrication of a high-density multi-level interconnect with external contacts. The composite dielectric layer consists of a polymer layer, typically a polyimide, which is deposited using conventional spin-deposit techniques. This process creates a planarized surface for the deposition of an inorganic layer, usually made of silicon dioxide or silicon nitride. The inorganic layer is then etched using standard photoresist techniques to form a mask for etching the polymer layer. A previously deposited inorganic layer serves as an etch stop, allowing for long over etches to achieve full external contacts. This advancement enables high-density interconnect systems on multiple levels.
