Integrated circuit designers at the Honeywell Inc. Solid State Electronics Center in Plymouth, Minn., are offering a four-layer metal interconnect for silicon-on-insulator (SOI) application-specific integrated circuit (ASIC) gate arrays. This extra layer of metal yields 50 percent more usable gates for existing ASICs with the same form, fit, and function. The four-layer metal process is a key feature for the next generation of SOI products, particularly ASICs and custom designs. Honeywell Solid State has Qualified Manufacturing List certification for its SOI 0.8-micron ASIC products and has a long-term commitment to radiation-hardened ASICs, company officials say. - J.K.
