Advanced Maskless Aligner

The MLA 150 is a dual wavelength advanced maskless aligner which offers precise, high-speed photolithography with front and backside alignment for prototyping, and small-scale production.

Cleanroom equipment, full laser-proof Class 1 housing with large yellow-tinted window for viewing. Heidelberg Instruments is inscribed on the front panel.

The MLA 150 is a direct-write lithography system that uses a laser and digital micromirror array to expose patterns onto photoresist-coated substrates, eliminating the need for physical photomasks. Using 405nm or 375nm lasers, it ensures compatibility with most UV photoresists, offering unparalleled flexibility for applications such as MEMS, micro-optics, and sensor fabrication. With global and backside alignment for multi-layer patterning, non-contact exposure, and high throughput, the system is ideal for rapid prototyping, research, and small-batch production.
