Gold Sputtering Target (Au, Purity: 99.99%)

Gold Sputtering Target

Introduction

Gold sputtering targets are composed of high-purity gold and are used in the sputtering process, a physical vapor deposition (PVD) technique. This process involves bombarding the target with energetic particles, which eject atoms from the surface that are then deposited onto a substrate to form thin films. Gold is prized for its exceptional electrical conductivity, chemical stability, and resistance to oxidation, making it an ideal choice for a variety of high-performance applications.
