Process application engineers often encounter a variety of complex challenges related to deposition by spin coating, as many variables affect the quality of the spin-applied coating. These variables have critical effects on the overall coating uniformity, coating thickness, and subsequent device yield. Some of the more influential variables that must be controlled precisely are spin…
Click Here to Read MoreOne of the most critical variables in spin-coating processes is coating uniformity. In many cases, engineers are challenged with achieving ultralow total thickness variation at high film thicknesses while conserving expensive materials. To achieve such a highly uniform coating, automated control of the solvent vapors is essential. A closed bowl environment combined with a programmable…

Sharing these results invariably leads to a potential customer asking, “Can you fill the holes in my substrate that are x in size?” The short answer to the question is “Yes, we can.” Filling…
