pinhole manufacture

A while back we had a discussion about the "perfect" pinhole, and how to
make it. Why not think in terms of growing them in a silicon chip?
The dimensions could be precisely controlled.

I saw an example of this a few years back so I know it is possible. It
was a research setting - some folks made chips with an array of holes
hoping to get nerve fibers to grow through them. For all we know, Intel
throws out latent pinhole cameras as defects all the time.

It would be worth a call to someone in the industry.
