Sreemanth, You will want to use the lowest pressure possible (during the deposition) and heat the substrate as high as you can. You might also consider performing an ion assisted deposition. -Mike U. of Louisville >>> "Sreemanth M Uppuluri"07/16/06 9:08 PM >>> Hello, I am trying to obtain very low surface roughness films of Aluminum on Quartz substrates using e-beam evaporation. Please let me know if there are any recipes specific to this issue such as speed of deposition, pressure and so on. Thanks Sreemanth
