*****************************************************************
The Evidence that Hagiwara at Sony is the inventer of Pinned Photodiode is
given by the three 1975 Japanese Patent Applications , JPA 1975-127646,
JPA 1975-127647 and JPA 1975-134985. Details are explained below.

*****************************************************************






Hagiwara is also the inventor of the Global Shutter Function
needed in the modern CMOS Image Sensors. For the details,
please read the conference publication papers:

Pinned Photodiode has an excellent short wave blue light sensitivity
that can be also applied to the Pinned Photodiode type Solar Cells.
