A series of connections of photodiodes has a plurality of alternating
N-type conductivity surface areas with P-type conductivity surface areas
with each member of the P-type conductivity surface areas being separated
by a member of N-type conductivity surface areas. Metal conductors connect
the P-type conductivity areas to the N-type conductivity areas at an N+
implanted area within the N-type conductivity surface area to form the
series connection of photodiodes.
