Laser micromachining
Investigations into the application of lasers for micromachining of silicon are also being carried out, including the drilling and scribing of deep vias and trenches and the initiation of crystal plane selective silicon etching. Rapid creation of deep features with minimal micro-cracking or laser induced damage is relevant to various complex solar cell designs, and also allows for the utilisation of various test structures that can be used for characterision of laser and other solar cell fabrication processes.
High-precision stage with galvo scanner.
The high-precision four-axis stage combined with a high-performance galvanometer scanner achieves µm accuracy at high speed over a scan area of 200 mm x 200 mm.
