Our photolithography process capability produces thin film coatings (including bandpass filters , absorption coatings and metal fiducials). We use both wet and dry film resist processes to create a pattern to suit your needs.
DSI’s photolithography capability enables production of patterned thin film coatings (including bandpass filters, absorption coatings, and metals) on substrates up to 6 inches in diameter.
DSI’s processes enable high placement accuracy, the ability to accurately maintain coating spectral properties at the smallest geometries, and two-sided patterning capabilities (for flat windows or filters). DSI utilizes both wet and dry film resist processes to support development and production of challenging patterned coating geometries for our customers.
