Laser Table equipment consists of a focused 5 watt argon ion laser beam (488/514 nm wavelength) with spot sizes down to 1 micron full width half maximum. An electro-optic shutter controls the beam pulse duration from single 2 microsecond pulse through to continuous exposure and multiple pulses. IC's are positioned below the beam using a laser interferometry controlled XY table with position accuracy of 0.1 micrometers over a 25x25 cm area. The table can move to locations and stabilize in less than 0.1 sec for distances less than 1 mm, and about 1 second for the full 25 cm. A TV camera image of the laser position area is displayed in the control system computer using a real time frame grabber on the TV microscope image. Digitally stored images can be taken of the cut points to verify the location of operations. IC's can be worked on in any of the following formats: chips or wafers, 24 or 40 pin DIPS, 64 pin-grid arrays. The combined laser, shutter and positioning system operates under a integrated MSWindows control system developed here at SFU. The system allows automatic moving to position, adjustment of the pulse parameters (duration, number of pulses, shape, etc.) and firing of the laser pulse. Scripts of control commands enable the table to move through a sequence of operations without needing any user input. Microfabriction and micromachining research work at SFU's Microfabriction Laboratory including oxidation/doping furnaces, film RF sputter deposition system, photolithography, wet etching stations and inspection/measurement equipment.
