Several large-format CCDs have been designed and are in process at the Loral Aeronutronics fabrication plant. One is an edge-buttable 2048 X 2048 device that will allow a 2 X 2 array to be formed with an imaging area measuring more than 61 mm on a side and with only 400 microns dead space between arrays. Another is a 3072 X 1024 CCD with both floating diffusion and non-destructive read floating gate amplifiers. Also included are smaller arrays of 2688 X 512 and 1200 X 800 in the chords of the wafers. All of these designs were accomplished by a non-specialist scientist using AutoCAD on an inexpensive PC, a level of customer interaction with CCD manufacturing not previously available.
