Manufacturing Tests

Hi,

can anyone point out a book, paper or webpage where manufacturing tests are described?

By manufacturing tests I mean before packaging, when the manufacturer determines whther a chip is defective or not

Thanks

Plug or die testing is done as part of the fab process. Go to your favorite book site and look up VLSI processes. Here's a start:

Peter,

Just out of interest, how is this done? Is a miniture bed of nails test rig used or is extra functionality designed into the wafer to allow test access to individual die?
