1.   Materials are deposited in a three-dimensional stack on a silicon base and whittled and shaped using photolithography, in which ultraviolet light is used for etching.

2.   Nikon said revenues increased because of strong sales of machines such as steppers, which imprint microscopic layers of electric circuitry onto the silicon bases of semiconductor chips.
