摘要
In this paper, the dehydration behavior of hydrogen-methyl-siloxane-based porous spin-on-glass (SOG) films after oxygen plasma exposure is reported. The resultant loss of hydrophohic groups from the plasma exposure makes the films hygroscopic and thus the film dielectric constant can significantly increase. We employed a simple method consisting of spin-on coating of hexadimethyldisilazane (HMDS) with successive hotplate baking so as to dehydrate the films and decrease the film dielectric constant.
