ETCHING

Lasers used to etch the above graphic into a gold circuit board. Copyright © 1974 Lillian F. Schwartz. All rights reserved.

To create my etched graphics I drew my own designs. Bob Tatum, at Bell Labs, used the Algortithm’s for silcon chips, the same methods that were developed  in the ’70s. My designs were etched onto the integrated circuits that needed to be bonded to the circuit boards, before deployment.
