Most chips are made using a photographic technique that shrinks the circuit pattern to a tiny size.
A plasma is then applied to the silicon to actually etch the circuit pattern.
These devices locate the circuit pattern by providing common measurable points.
The membranes contain the circuit pattern to be etched.
The most common of these circuit patterns are shown in Figure 1-3.
Essentially, you use a slide projector to project an image of the circuit pattern on a wafer.
Then they etched a circuit pattern about a third of an inch long using lithographic techniques that are standard in the computer industry.
The greatest challenge today, he added, is to draw circuit patterns on these masks with extreme accuracy.
Silvery traces glowed on the walls like living circuit patterns.
This makes it virtually impossible to memorize circuit patterns to win.
