Inverted cylindrical magnetron (ICM) sputtering is the optimal choice for applications that require ultra-uniform coatings on flat substrates. For example, ICM sputtering offers uniformity below 1% on standard 200mm wafers. ICM sputtering follows the same steps as conventional magnetron sputtering except a cylindrical cathode is used instead of a planar cathode. Instead of sputtering up… Read More
