===Process information===
==Process information==
The Aligner: MA6-2 has an i-line notch filter installed. This results in an exposure light peak at 365nm. Compared to exposure on the KS Aligner, the optimal dose should be very similar. The 500W Hg-Xe lamp also enables exposure in the DUV range around 240nm. This functionality is not established yet, partly due to safety concerns.

=== Equipment performance and process related parameters ===
==Light intensity and uniformity after lamp ignition==
 
[[image:MA6-2_light_intensity_and_uniformity_from_ignition.png|400px|right|thumb|Light intensity and uniformity after lamp ignition. CP is constant power mode, CI is constant intensity mode. The accept limits for the CI mode is ±5%, the accept limit for the non-uniformity is 2%. CP mode has no accept limit.]]
 
The lamp requires about 15 minutes of on-time after lamp ignition, before the light output has stabilized, and users using the constant power mode should always wait for 15 minutes after ignition, before starting processing.
 
If users use the constant intensity mode, this waiting time is not necessary, since the internal light sensor automatically adjusts the output to match the setpoint value.
 
The non-uniformity of the light, in CI mode, is unaffected by the stabilization time.
