The flexures have been prepared by different fabrication techniques. A lowest mechanical loss of $3\\times10^{-8}$ was observed for a 130 $\\mu$m thick flexure at around 10 K. While the mechanical loss follows the thermoelastic predictions down to 50 K a difference can be observed at lower temperatures for different surface treatments. This surface loss will be limiting for all applications using silicon based oscillators at low temperatures.
