Paper Abstract

CdSe was the semiconductor used in the pioneering active matrix work of the 70''s. Today''s active matrix industry has chosen to disregard this material and is concentrating almost exclusively on Si films. This paper shows the historical roots of this decision, which in the author''s opinion has put the industry on a false trail, hindered the full development of the original concept of a fully integrated display subsystem and has resulted in excessive manufacturing cost. Important recent contributions to CdSe TFT technology are reviewed in the paper, followed by a comparison of the critical physical and fabrication parameters of CdSe, (alpha) -Si and poly-Si. These sections present an incontrovertible argument for an industry-wide reconsideration of an unjustly neglected material.
