Abstract: A disk shaped ceramic support has a mounting surface provided as a unitary part of the support with conductors extending generally outward from the mounting surface through the thickness dimension of the support, the outer ends of the conductive leads being connected to a ring of terminal leads. A charge coupled device (CCD) imager chip is secured to the mounting surface to leave a backside illumination surface of the chip unobstructed and electrical interconnections are made from terminal pads on the front surface of the chip to the ends of the conductive leads adjacent the mounting surface. A cover plate attached to the insulating support outwardly of the interconnections encloses the front surface of the chip. In a preferred structure the chip is mounted on an apertured molybdenum disk unitarily attached to the support with the illumination surface of the CCD chip facing the aperture.
