Standing Stepper With Dumbbells, Resistance Band And Twister.

The stepper conducts light exposure through a mask to project the circuit’s image, much like a negative image in standard photography. Here’s how it works: The stepper is loaded with silicon wafers with a photo-resistive coating. A robotic arm grabs a wafer and sets it on a wafer stage. The wafer is aligned, and then light (perhaps extreme ultraviolet) is cast through a quartz plate with a chrome pattern of the circuits that will be created.
