A PtSi Schottky-barrier area imager with meander-channel CCD readout registers

This paper describes improvement of the fill factor of Schottky-barrier infrared CCD arrays by using a meander-channel CCD (MCCD) as both the vertical and the horizontal readout registers. A 64 × 64 element monolithic Schottky-barrier infrared meander channel CCD(SB-IRMCCD) with 23 percent fill factor has been fabricated with negligible element to element cross talk. This letter also describes how a fill factor of 57 percent is possible by decreasing the area of the vertical MCCD register to 30 percent of that in the present device.
