Molecular Vapor Deposition Tool for Surface Modification
Manager: Christopher AlphaBackup: Michael Skvarla
The large surface-area-to-volume ratios of surface and bulk micromachined micro and nanomechanical structures can cause unintentional adhesion of device components, referred to as stiction. Stiction occurs when restoring forces are unable to overcome interfacial forces such as capillary, van der Waals and electrostatic attractions. This results in permanent adhesion of device components to undesired surfaces. Consequently, anti-stiction coatings for micro and nanoelectromechanical systems (MEMS and NEMS, respectively) and information technology devices (e.g. hard disk storage media) have found wide spread use.
In the current tool configuration, only two precursors are available at the tool. Changing a precursor requires several hours work and therefore is only available by several days advanced notice. The currently loaded precursors and change schedule is as listed below:
