Originally we had a standard chamber. The coating was very inconsistent. We contact EMS and EMS sent us an extended height chamber <span style="color: rgb(0, 0, 0); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;">and advised us to control the coating by monitoring the FTM (Film Thickness Monitor) reading instead of by editable profiles.</span> It does make the coating more controllable. However, the results are still not consistent. For example, I coated carbon of 9 nm by FTM and also carbon of 12.5 nm by FTM. The 9 nm thick carbon actually looked thicker than 12.5 nm. I would appreciate it if users here can share your experience with me. </div><div><br></div><div>Thanks,</div><div><br></div><div>Guobin</div><div><br></div><div><br></div></div></body></html>
