IPC: H01L27/14
Filed: 2003-02-07
Abstract: <P>PROBLEM TO BE SOLVED: To reduce errors in a photodetector caused by the interference band made by a cover glass covering the photodetector such as a CMOS sensor.  <P>SOLUTION: A lower surface 286b of a transparent protective layer 286 is inclined against the detection surface 282a of the CMOS sensor 282 by an inclination angle θ. Thanks to the lower surface 286b inclined in this way, an incident light transmitted through the transparent protective layer 286 interferes and the interference band is formed on the detection surface 282a of the CMOS sensor 282. An interval between the bands (d) of the interference band can be controlled by the inclination angle θ, and the interval between the bands (d) is made equal to a pixel size of the CMOS sensor 282 or less. Consequently, unevenness of contrast of light on the detection surface 282a is prevented. As a result, the deviation in measurement of the CMOS sensor 282 caused by the interference band caused by the transparent protective layer 286 is reduced.  <P>COPYRIGHT: (C)2004,JPO
