Product Range

We supply P-Type Test Wafer which is manufactured under show unparalleled outstanding performance by virtue of high density, excellent purity, and distinguished homogeneous microstructure. The popular geometries featuring with both planar and rotatable shapes, such as circular, rectangular, ring, tube, cylinder and conicity, are all available. If you have your own unique requirements about the sputtering targets, no matter in density, purity, homogeneity or in geometry, please let us know exactly what you need. We'll do our utmost to meet your requirements precisely.
