Claim 16:
17. A device, comprising:
an intrinsic region;
a doped region in the intrinsic region;
a ring-shaped region around the doped region, the ring-shaped region extending into the intrinsic region further than the doped region; and
an insulator on the intrinsic region, on the ring-shaped region, and partially overlapping the doped region,
the doped region having a first dimension in a first direction between portions of the ring-shaped region, each portion of the ring-shaped region having a second dimension in the first direction, the second dimension being less than the first dimension,
the insulator having portions that are in contact with the portions of the ring-shaped region, the portions of the insulator having a third dimension in the first direction, the third dimension being greater than the second dimension.
