What it is

The MA 6 / BA 6 IR is a mask aligner manufactured by SUSS MicroTec.[1][2]

The MA 6 / BA 6 IR is categorized as a lithography tool.[2]

How it works

General reference — not yet source-verified

A contact and proximity mask aligner brings a photomask and substrate into contact or within a small gap, then exposes the substrate through the mask with ultraviolet light.

The IR variant of the system adds infrared illumination, which passes through the substrate material and allows alignment marks on the back side of the wafer to be viewed from the front side. Back-side alignment capability permits a pattern on one face of the substrate to be registered to structures patterned on the opposite face.

Where it fits in the process flow

General reference — not yet source-verified

The exposure step performed by a mask aligner follows resist coating and soft baking and precedes resist developing in the lithography sequence.

Applications

General reference — not yet source-verified

Applications for contact and proximity mask aligners include micro-electromechanical systems, compound semiconductor devices, power semiconductors, and optoelectronic components.

The back-side alignment configuration of the system is used for double-sided wafer processing, where patterns on the front side must align to patterns on the back side. The infrared illumination feature supports alignment through substrates that are not transparent to visible light.
