'''CHIPAL [mode]''' | |||
'''CHIPAL''' has six modes | |||
*0 - Cancels chip alignment | |||
*S - SEM mode. The user is prompted to use SEM mode to manually find M1 | |||
*1 - One mark is used for position correction | |||
*4 - Four marks are used for position, rotation and gain correction | |||
*V1 - Virtual mode 1. A single mark position is used for height detection of the substrate, no position correction | |||
*V1 - Virtual mode 4. Four mark positions are used for height detection of the substrate, no position correction | |||
In addition to position correction mode 1 and 4 also detects substrate height. The virtual modes are only used to detect substrate height since no mark detection is done. | |||
