The LSST focal plane array (FPA) will consist of an order of magnitude more pixels than any imaging array realized so far. The sensors must produce low read noise, high QE at 1 micron, and a very tight PSF. This will all be necessary to do the science at the LSST. For an FPA involving about 200 large format (4k x 4k) sensors, an industrial approach has to be developed and adopted. In this initial phase of sensor development, we have targeted specific technology experiments at selected vendors, with the goal of establishing both the technical characteristics of actual sensors, based on our projected requirements, and the industrial feasibility of their production. We have chosen to fund three projects in this initial development phase, two involving CCD technology and one utilizing hybridized PIN-CMOS architecture. Initial test results from the first devices in a smaller format resulting from this study program will be presented. Design concepts for assembly of the large format sensors into larger modules (rafts) containing 3 x 3 sensors each, with their readout electronics, will also be presented.
