Precision optics applications require thin film coatings to meet very exacting specs for factors such as refractive index, optical loss, thickness, optical transmission and uniformity. To do this, manufacturers need a full precision optics coating system configured with in-situ control that directly monitors optical properties. Effects on Performance and Yield In precision optics, the acceptable… Read More

In large-scale, high-volume silicon semiconductor production, such as for microprocessors and DRAM, manufacturers often prefer direct handling of wafers during the thin film deposition process. This makes perfect sense for mass-producing wafers that are all 300mm in size. However, in the compound semiconductor industry, multiple wafer sizes are quite common. It is not economically viable… Read More

Thin film deposition methods such as evaporation for indium bump deposition are often ideal for achieving good lift-off for patterned coatings. However, evaporation techniques can fall short of production needs for high-volume manufacturing. High-volume applications often require magnetron sputtering as a deposition method. The challenge for these manufacturers is to achieve good lift-off while meeting… Read More

Extreme ultraviolet (EUV) light requires a very complex process to produce, but this technology has major implications for lithography and nano-machining in semiconductor manufacturing. To ensure performance and precision during manufacturing, components of EUV systems must be produced with high-precision optics and coatings. What is Extreme Ultraviolet Light? Extreme UV light has wavelengths anywhere between… Read More

One design consideration that can affect your process and thin film coating performance is the collective orientation of the substrate and cathodes during magnetron sputtering. Your system configuration may be oriented either horizontally or vertically, and both orientations have their benefits and tradeoffs. Vertical Sputtering: Benefits In a vertical sputtering configuration, the substrate and cathodes… Read More

While thin film deposition is often used to create a continuous coating on a substrate, there are many applications where a patterned coating is required. These patterns create bumps, trenches or ridges across the surface of the substrate. This coating type is used for 3D applications, such as electrical interconnects. Focal plane arrays with high-density… Read More
