How To Specify Optical Coatings For Sensor Applications
With over 30 years of optical coating experience, Deposition Sciences, Inc. has learned a thing or two about the intricacies of our specifications. This year at SPIE’s DCS exhibition, Kevin Gibbons offers some advice on what you should consider before determining an optical coating’s specifications for sensing applications.
DSI Thin Film Coating Technologies
An optical thin film consists of one or more layers of dielectric material or metal, with individual layer thicknesses typically ranging from a few nanometers to several microns. In the case of dielectrics, these modify the reflectance and transmittance characteristics of the underlying substrate through the mechanism of optical interference, based on the exact thickness
The drive towards smaller sensors, often integrated on monolithic substrates with other processing electronics, has created a need for coatings directly on semiconductor wafers, or on miniaturized substrates that can readily be assembled with active devices. DSI utilizes photolithography to produce a wide array of precision patterned thin film coatings (such as antireflection coatings, bandpass filters, dark mirrors, and metals), with feature sizes as small as 5 µm, on substrates up to 8 inches in diameter.
MicroDyn® is DSI’s proprietary version of magnetron sputtering optimized for high throughput. MicroDyn® utilizes an octagonally shaped chamber, where electrically conductive (metal or semiconductor) coating targets are arranged around the periphery, and the parts to be coated are held on a cylindrical rotating drum concentric within the chamber. Unlike other optical coating methods, sputtering does not require heating the coated parts. This allows the technique to be used on a wide range of substrate materials, as well as on assemblies that may incorporate plastic parts.
