NASA's Glenn Research Center is seeking information from potential sources for the fabrication of 4H-SiC Silicon Carbide (SiC) integrated circuit structures, specifically JFETs and resistors, on 100 mm diameter SiC wafers. The objective is to utilize a designated fabrication process flow to meet specific technical specifications using NASA-provided design files, with the completed wafers returned to NASA for further processing. These integrated circuits are crucial for developing prototype electronic systems capable of operating in extreme environments for NASA missions. Interested firms are invited to submit capability statements by April 21, 2025, to Claude David at claude.e.david@nasa.gov, referencing notice number 80GRC025R7012SS.
