  • Solid-state image pickup device including lens unit held by holding section included in same lens unit, and electronic apparatus including same solid-state image pickup device
    Patent number: 8072538
    Abstract: A camera module 100 of the present invention is arranged such that a lens barrel 32 is provided with an internal screw thread 32a on its internal side, and that a holding section 41, which is a portion of a lens holder 4, the portion holding a lens unit 3, is provided with an external screw thread 41a on its external side, the external screw thread 41a being engaged with the internal screw thread 32a. As a result, it is possible to provide the camera module 100 capable of preventing contamination by dirt into a light path and thereby reducing imaging defects.
    Type: Grant

  • Method of making a mask ROM
    Patent number: 6008093
    Abstract: A semiconductor device fabrication method is provided which comprises the steps of: (i) forming a plurality of high concentration diffusion layers of a second conductivity in a semiconductor substrate; (ii) forming a plurality of first gate electrodes extending perpendicularly to the high concentration diffusion layers of the second conductivity on the semiconductor substrate with a first gate insulating film interposed therebetween; (iii) implanting ions of a first conductivity into surface portions of the semiconductor substrate for device isolation by using the first gate electrodes as a mask; (iv) forming side wall spacers on side walls of the first gate electrodes; (v-i) implanting ions of the second conductivity into surface portions of the semiconductor substrate for formation of channel regions by using the first gate electrodes and the side wall spacers as a mask; (vi-i) forming a plurality of second gate electrodes on the ion-implanted channel regions between the first gate electrodes; and (vii) imp
