Enabling Sputtering from the Target Only Bias Target Sputtering (BTS) has excellent process control and stoichiometry while reducing contamination and lowering cost of ownership. The ultralow contamination leads to higher performance in lasers and fewer defects enables higher laser damage threshold. BTS is also used for EUV mask blanks which must be defect-free or the… Read More

The process tunability of PIB-CVD makes it optimal for many thin film applications. The inherent tunability of PIB-CVD enables a wide range of film properties including flowable, soft, thin film encapsulation layers as well as hard, highly hydrophobic, and optically clear coatings. As a result, multilayer and gradient coatings can be produced in a single chamber from… Read More

Tungsten coatings are commonly used in semiconductor applications and have the potential to be used in emerging solar energy applications. These thin films are commonly subject to high stress and low adhesion, but when manufacturers try and compensate for stress, it leads to increased resistivity. In order to achieve the best performance and repeatability for… Read More

Medical devices often require thin film coatings to optimize performance and longevity, while also ensuring patient safety. Because these devices often feature unique properties compared to “normal” substrates, such as a completely curved or flexible structure, they have challenging thin film deposition process requirements. Magnetron sputtering with an inverted cylindrical cathode is one thin film… Read More

One of the most important requirements for precision optics is thickness uniformity of thin film coatings. Achieving a high degree of uniformity on flat optics usually requires complex motion or restricted deposition zoned, which often lowers deposition rates. For curved optics, there is no practical way to achieve the uniformity needed through a conventional thin… Read More

To form indium bumps, a patterned mask is applied to the wafer and then indium is deposited. The patterned mask has “holes” that allow some indium to deposit directly onto the wafer, while the rest of the indium is deposited onto the mask. After indium bump deposition, the unwanted indium and the mask must be… Read More
