A method of continuous manufacture of semiconductor integrated circuits, said method and apparatus adapted to contain the semiconductor substrate, semiconductor deposition coating processes, and etching processes within a substantially collocated series of process chambers so that the semiconductor travels from one chamber to the next without exposure to airborne impurities and contact with manufacturing personnel. The invention has particular utility in the high volume fabrication of large surface area semiconductor circuits such as active matrix liquid crystal displays. The present invention contains a roll-to-roll and continuous belt embodiment.
