first plurality of diffusions doped with a second dopant type and
formed on the first planar surface of the substrate, while a second
plurality of diffusions are doped with the first dopant type and
formed on the first planar surface of the substrate interposed the
first plurality of diffusions (Brief, page 2). Representative
independent claim 1 is reproduced below:
1. A distributed photodiode, the photodiode comprising:
a substrate, the substrate being doped with a first dopant
type and having first and second planar surfaces;
a first plurality of diffusions, the first plurality of
diffusions being doped with a second dopant type and formed on the
first planar surface of the substrate;
a second plurality of diffusions, the second plurality of
diffusions being doped with the first dopant type and formed on the
first planar surface of the substrate interposed the first
plurality of diffusions; and
a first contact having a first plurality of connective traces
disposed on the first planar surface of the substrate and coupled
to each of the first plurality of diffusions.
