A lithography system for providing interconnections of integrated circuits on a substrate includes a laser system with a high reflector and an output coupler that define an oscillator cavity. A gain medium and a mode locking device are positioned in the oscillator cavity. A diode pump source produces a pump beam that is incident on the gain medium. A processor is coupled to the laser system and stores a representation of interconnections for the integrated circuit. An output beam directing apparatus is coupled to the processor and directs the output beam to the substrate and form the interconnections.

Quasi-continuous wave lithography apparatus and method

An inspection apparatus includes a laser system. The laser system has a high reflector and an output coupler that define an oscillator cavity which produces an output beam. A gain medium and a mode locking device are positioned in the oscillator cavity. A diode pump source produces a pump beam that is incident on the gain medium. An output beam directing apparatus directs the output beam to the surface of the article. A surface flaw at the surface of the article produces scattered light from at least a portion of the output beam incident on the surface flaw. A detector is positioned to detect the scattered light.

Method and apparatus to detect a flaw in a surface of an article

A laser writing system includes a high reflector and an output coupler that define an oscillator cavity. A gain medium and a mode locking device are positioned in the oscillator cavity. A diode pump source produces a pump beam that is incident on the gain medium and an output beam is produced. A support holds a workpiece. Means are provided for directing the output beam across the workpiece.
