A series of W, WSi2, Si thin films and W/Si, WSi2/Si periodic multilayers were fabricated by using DC magnetron sputtering technology. Surface profiles before and after deposition were measured with a stylus profiler and the stresses were calculated. The results indicate that W thin films show relatively large compressive stress, while W/Si multilayers show tensile stress. Both WSi2 thin films and WSi2/Si periodic multilayers show compressive stress. WSi2/Si periodic multilayers have the most stable stress state with no sharp change, and is a good material combination for X-ray multilayer optics with a large number of bilayers.
