First Claim
1. A photodiode comprising:
- a first region comprising substantially intrinsic semiconductor material, the region having a first side and a second side opposite to the first side;
a second region comprising highly-doped p-type semiconductor material formed proximate to the first side of the first region;
a third region comprising highly-doped n-type semiconductor material formed proximate to the second side of the first region; and
a fourth region comprising one of;
(i) highly-doped p-type semiconductor formed between the first region and the third region, or (ii) highly-doped n-type semiconductor formed between the first region and the second region.

Abstract
A photodiode may include a first region comprising substantially intrinsic semiconductor material, the region having a first side and a second side opposite to the first side. The photodiode may also include a second region comprising highly-doped p-type semiconductor material formed proximate to the first side of the first region. The photodiode may additionally include a third region comprising highly-doped n-type semiconductor material formed proximate to the second side of the first region. The photodiode may further include a fourth region comprising one of: (i) highly-doped p-type semiconductor formed between the first region and the third region, or (ii) highly-doped n-type semiconductor formed between the first region and the second region.
