Active Matrix Liquid Crystal Displays, AMLCD's, based on Cadmium Selenide Thin Film Transistors, have been developed by Litton for a number of defence/avionics applications. Fabrication processes for the thin film transistors (TFT) arrays, colour filters and liquid crystal cell assembly have been developed which enable the end product to meet the difficult environmental and performance specifications of military applications, while maintaining focus on cost and yield issues. The fabrication of the AMLCD products is now transitioning into a new production facility which has been designed specifically to meet the requirements of the defence/avionics marketplace. This paper describes the principle features of Litton's CdSe TFT AMLCD manufacturing process. Manufacturing considerations in establishing production capability to meet the unique requirements of defence applications, and details of the new facility and equipment, are discussed.
