Maskless Aligner (Heidelberg MLA150)
Tool Type Lithography
Location Bay 6
Supervisor Biljana Stamenic
Supervisor Phone (805) 893-4002
Supervisor E-Mail
Description Maskless I-Line Photolithography
Manufacturer Heidelberg Instruments
Model MLA150
Materials I-Line Photoresists


The MLA150 allows for arbitrary direct patterning of I-Line photoresists, directly from a CAD drawing/file, and alignment to arbitrary features on the sample. The system uses a optical digital light process (MEMS light-field patterning) to programatically expose digitized patterns directly onto the sample - no glass photomasks/reticles are required.
