Sputtering is a physical vapor deposition (PVD) technique that utilizes the momentum transferred from energetic ions (usually from a plasma source) to dislodge atoms from a solid target—in this case, the chromium sputtering target. The ejected atoms then condense onto nearby substrates, forming a thin film. This method is favorable due to its ability to produce high-purity and uniform films, which are essential in high-performance applications.
Chromium sputtering targets can be made from various purity levels, with high-purity targets (99.9% or greater) being preferred for electronic and high-tech applications. The physical and chemical properties of chromium—such as its hardness, corrosion resistance, and ability to form stable oxides—enhance the performance of the deposited films. Moreover, the conductive nature of chromium is beneficial for applications in electronics and optoelectronics.
Chromium sputtering targets find applications across a diverse range of industries. In the semiconductor industry, chromium thin films are used in etching, masking, and as conductive layers in various electronic devices. The optical industry benefits from chromium coatings for mirrors and filters due to their reflective properties. Furthermore, chromium is used in decorative coatings to provide aesthetic appeal and durability on various consumer products.
