Abstract In this month, the team mostly focused on diamond deposition. Diamond films with 4 boron doping levels were deposited. Although this month's work revealed some challenges in accurately controlling the resistivity in the diamond films, the films were manufactured successfully and will be delivered on time. Part of the characterization of the diamond films including thickness, resistivity, residual stress and Raman spectra measurement is finished. Raman spectra shows basically regular nanocrystalline diamond signature as expected. In this STTR phase I project, Advanced Diamond Technologies worked with Princeton University to fabricate and characterize Strain-Modulated Diamond Nanostructures for Next-Generation, Biocompatible Nanoelectromechanical Systems. During the 6-month work effort, all three major tasks including the subtasks are accomplished on time. We have accomplished the following: (1) Delivered diamond film with designed thinness, grain size and doping levels for the fabrication of diamond nanoribbons; (2) Developed stress control of diamond film to facilitate ribbons release; (3) Studied pinhole density of diamond film and developed two new methods to decrease pinhole density for super thin.
