Optical sensor package and method of making same
First Claim
1. A package mountable on a support substrate, the package comprising:
- an image sensor;
a base substrate, the base substrate constructed of an insulating material, the image sensor carried on a surface of the base substrate;
a plurality of conductive strips on the base substrate extending toward the periphery of the base substrate, the integrated circuit optical sensor electrically connected to the conductive strips;
clips to clip onto the base substrate such that they hold onto the substrate, and to electrically connect to the conductive strips;
a window; and
a seal material, the window bonded to the surface of the base substrate in a spaced apart relationship by the seal material, the seal material extending from the window to the surface and providing a seal around the sensor, and wherein the image sensor is positioned between the window and the base substrate whereby the seal material, the window and the base substrate form a sealed cavity for the optical sensor and the window admits light to the optical sensor.

Abstract
A package that encapsulates an integrated circuit optical sensor and mounts on a support substrate includes a base substrate constructed of an insulating material. The optical sensor bottom surface is bonded to the base substrate top surface. Conductive strips on the base substrate top surface extend from a region near the optical sensor to an edge of the base substrate top surface. Wires are bonded on one end to a sensor bonding pad for which connection is desired and on the other end to a corresponding conductive strip. A window is bonded to the base substrate top surface in a spaced-apart relationship using seal material extending around the sensor enclosing each wire bond. Various means are provided for connecting each conductive strip to a corresponding trace on the support substrate. An electrochromic variable attenuator may be formed on the window, allowing control over the intensity of light striking the optical sensor.
