Abstract
A solid state image pick-up device has a rigid retainer having a hollow space, a resilient plate member closing the hollow space, a charge coupled device integrated on a semiconductor chip mounted on the resilient plate member, an optical lens focusing an image on a photo-electric converting region of the charge coupled device and an actuator connected between the bottom surface of the retainer and the resilient plate member so as to deform the resilient plate member and the semiconductor chip, thereby adjusting the surface of the semiconductor chip to a focal plane.
Claims14
A solid state image pick-up device comprising
- a retainer having a hollow space open to one end thereof,
- a resilient plate member provided in said hollow space,
- a semiconductor chip having an integrated circuit containing a charge coupled device and fixed to said resilient plate member so as to be conformable to said resilient plate member,
- a lens spaced from said semiconductor chip so as to focus an optical image onto a portion of said semiconductor chip where said charge coupled device is fabricated, and
- an actuator connected between said retainer and said resilient plate member so as to deform said resilient plate member.
