Title: Method for driving solid state image pickup element and solid state image pickup device
Inventor: TO TOMOAKI
IPC: H04N5/355
Filed: 2000-07-07
Abstract: PROBLEM TO BE SOLVED: To solve the problem that exposure time for two signals become discontinuous because the exposure operation is once interrupted by an electronic shutter since the exposure amount is heretofore regulated only by the electronic shutter, so that at a photographing time of a moving object a composite signal of the two signals becomes unnatural in a solid stage image pickup device for outputting two signals having different exposure amounts independently by conducting twice a read operation in one field period. SOLUTION: A method for driving the solid state image pickup element comprises the steps of starting the exposure of a second exposure signal immediately after reading a first exposure signal, and regulating the exposure amount of the second signal by varying read timing of the second signal. Thus, the exposure operations of the first and second signals become continuous, and hence even if the object moves, unnaturalness of the composite signal from the two signals can be avoided.

Title: Semiconductor light receiving element and manufacturing method
Inventor: YAMAGUCHI TADAHISA
IPC: H01L31/10
Filed: 2000-07-12
Abstract: PROBLEM TO BE SOLVED: To reduce variation in sensitivity caused by fluctuation of the film thickness of a surface film at a light receiving face in a semiconductor light receiving element. SOLUTION: A light receiving face 110 of a photo diode 2 is virtually separated into two regions, and SiO2 surface film 8 and 10 with different thickness are formed on the surface of each region. The first difference in film thickness between the film thickness T1 of the surface film 8 and the film thickness T2 of the surface film 10 is made almost equal to a difference of thickness between the film thickness having the largest optical reflectivity and the film thickness nearest to it and having a smallest reflectivity when the surface films are made of the same material as the surface films 8 and 10. In this case, the whole reflectivity of the surface film becomes a weighted average of each regional reflectivity with weight balance of each regional area.  Even when there is a variation in reflectivity caused by fluctuation of the film thickness, the variation in the whole reflectivity can be reduced through the average, and a variation in sensitivity of the photodiode can be reduced.
