Study on Mo Films Deposited by Using Pulse Laser and Magnetron Sputtering Techniques L Xue—chao ,ZHANG Yong—bin,ZHANG Hou—liang,REN Da—peng, LANG Ding~mu,ZHANG Yan—zhi (State key Laboratory of Surface Physics and Chemistry,Sichuan,Mianyang,621900,China) Abstract:The PLD and MS techniques were employed to prepare the Mo films,of which the surface morphology and cross section stucture、film thickness and surface roughness、and film density were characterized by using SEM、white light interfer— ometer and XRD respectively.The results indicate that the surface morphology and structure of the Mo flims deposited by PLD are dependence of the pulse energy and substrate temperature.The higher the energy are,the more defect of the Mo surface. As the evelated temperature.The Mo films by MS are dense and appear typically columnar growth.All of the films by PLD and MS have a good surface roughness of the Rqvalues less than 20nm and are consistent uniformity in thickness.Also,the expri— mental results are discussed.
