Multiple mask lithography

Photolithography is a technique that transfers a pattern from a photomask to a substrate coated with a light-sensitive material called photoresist. The pattern is created by exposing the photoresist to light from a source through the mask, and then developing it in a solution. The substrate can then undergo other processes such as deposition or etching. Some devices may require multiple photolithography steps with different masks, which need to be aligned precisely to the previous layers. For this purpose, mask aligners are used to ensure accuracy and control the exposure conditions.

Melbourne Centre for Nanofabrication VIC Node
Description
The PhableR tool provides unprecedented ability to print high resolution periodic structures in a low-cost, table-top system.Structures such as sub-micron period linear gratings and 2D patterns such as hexagonal and square lattices are printed with high uniformity and fidelity.
Related Information
The PhableR-100C uses DUV for patterning at high resolution below 300nm pitch and exposures are non-contact, protecting wafers and masks from physical contact and contamination.

Mask Aligner for Lithography
Australian National University (ANU) Optofab Node
Description
Mask aligner used for Lithography
Related Information
Mask aligner used for 4 inch/100mm wafers,Intensity 2-4 mW/cm2 in I-line mode. The MA-6 mask aligner operates in I-line mode currently only on 100mm or 4” wafers. Under ideal circumstances with very clean substrates and masks, we have printed sub 0.5um features on this system, but its resolution is essentially limited by substrate quality.

Mask Aligner- Canon MPA500-FAB
Optical Lithography
Australian National University (ANU) Optofab Node
Description
The MPA-500 aligner operates in broadband exposure mode only on 100mm or 4” wafers using 5” mask plates. The “MPA” stands for Mirror Projection Aligner and so the optics is completely achromatic being reflector based so the broadband exposure is not an issue in resolution terms and in fact speeds up exposure using more of the 2kW arc lamp spectrum.
