μMLA The Table-Top Maskless Aligner
CONFIGURABLE AND COMPACT TABLETOP MASKLESS ALIGNER WITH RASTER SCAN AND VECTOR EXPOSURE MODULES
The tabletop µMLA system is state-of-the-art in maskless technology built on the renowned µPG platform – the most sold tabletop maskless system worldwide. It is a perfect entry-level research and development (R&D) tool for virtually any application requiring microstructures. Typical examples are microfluidics (cell sorting devices, lab-on-a-chip), small-scale mask-writing, micro-optics and microlens arrays, sensors, MEMS, contacting 2D materials and fan-out electrodes, etc.
The µMLA is a flexible and customizable tool, and offers two exposure modes. The standard µMLA uses the Raster Scan Exposure Mode for exposures, which is fast and provides excellent image quality and fidelity, while the write time is independent of structure size of pattern density. The optional Vector Scan Mode is designed for patterning continuous smooth curves such as waveguides in a faster and more accurate way. Three optical setups offer a choice of variable resolution and throughput. Each allows easy switching between different resolution and speed configurations to optimize exposure for a given application. The Draw Mode enables straightforward ad-hoc modifications to existing structures and electrical contacts to nanowires or 2D materials. The grayscale exposure mode allows the creation of complex 2.5 structures such as micro-optical devices. With its small footprint, the µMLA fits on a regular table.
