Patent ID: 8410396

Claim:
Apparatus for drilling holes in a first material positioned on a second material, wherein said first material has a bottom surface, comprising, a laser system that produces a first laser beam for rapidly removing the bulk of material in an area in said first material to form a ragged hole in said first material, a control connected to said laser system that controls said laser that produces a first laser beam for rapidly removing the bulk of material in an area in said first material to form a ragged hole in said first material and stops said first laser beam in forming a ragged hole before said ragged hole reaches said bottom surface leaving a membrane between said ragged hole and said bottom surface, and a second laser beam for accurately cleaning up said ragged hole so that the final hole has dimensions of high precision, wherein said control connected to said laser system controls said second laser beam for accurately cleaning up said ragged hole so that the final hole has dimensions of high precision and for producing said final hole that has dimensions of high precisions is produced through said membrane to said bottom surface providing said final hole that has dimensions of high precisions through the first material to the second material.
