A method of cleaning and treating a device, including those of the micromechanical (10) and semiconductor type. The surface of a device, such as the landing electrode (22) of a digital micromirror device (10), is first cleaned with a supercritical fluid (SCF) in a chamber (50) to remove soluble chemical compounds, and then maintained in the SCF chamber until and during the subsequent passivation step. Passivants including PFDA and PFPE are suitable for the present invention. By maintaining the device in the SCF chamber, and without exposing the device to, for instance, the ambient of a clean room, organic and inorganic contaminants cannot be deposited upon the cleaned surface prior to the passivation step. The present invention derives technical advantages by providing an improved passivated surface that is suited to extend the useful operation life of devices, including those of the micromechanical type, reducing stiction forces between contacting elements such as a mirror and its landing electrode. The present invention is also suitable for cleaning and passivating other surfaces including a surface of semiconductor wafers, and the surface of a hard disk memory drive.
