About

This system is a dual-use mask aligner and wafer-bond aligner. Mask alignment is used for contact and proximity exposure processes. Exposures can be done with gaps programmable from 0 um to 300 um in 1 um increments. Automatic wedge compensation is used to ensure that the mask and wafer are parallel. Lithography can be done on wafers from 2” to 6” in diameter. Piece parts are better handled on the MJB-3 aligners. An automated image capture system is used for alignment at 5x, 10x, or 20x magnification. Programs are stored as recipes on the computer controlled unit. The system is fitted with visible, bottom-side optics, back-side alignment capability. The lamp is a 350 W Hg-Arc lamp, providing significant power in the g-h-and i-line regime. Integrated light level sensing ensures proper exposure doses as the lamp degrades. Bond alignment can be done on 3” to 6” wafers. The bond alignment is done with special fixturing to allow aligned samples to be transferred to the Karl-Suss SB6 system.
