THERMO-MECHANICAL OVERLAY SIGNATURE TUNING FOR PHOTOLITHOGRAPHIC MASK ALIGNER |
摘要 |
Thermoelectric heat pumps are individually located at multiple flexures functioning to support a primary mirror which mirror reflects light from an aluminum mask onto a semiconductor wafer. The heat pumps are selectively energized to apply thermal stresses by heat or cold application at the flexures into the primary mirror suspension to compensate for distortions in the image transfer between the mask and the semiconductor wafer. |
