  1. Meso Machining Norman Salmon Engineering Program Manager Lawrence Berkeley National Lab njsalmon@lbl.gov

  2. silicon µ-machining miniature machining meso machining • Meso-scale machining: 10 µm ~ 1mm bridging the gap between silicon based MEMS and conventional miniature machining. 10-3 10-4 10-510-6 [m] Critical dimensions

  3. Micro Milling, Drilling and Turning Micro Stepper Motor Laminates - Produced Using 100 Micron Diameter Rotary Cutting Tools - Tech Transfer Grant for Empire Magnetics FY2002 100 Micron Diameter Micro Electrodes Produced for Alexander Zholents 2002 AFRD LDRD Holes as small as 40 Microns can be drilled in Stainless Steel - Shown is a 70 Micron Drill compared with a Human Hair

  4. Micro Engine Components 1mm Micro Rotor Micro Turbine 1mm 1mm

  5. Electroplated RF Electrode 125 micron

  6. Meso-Machining Examples FIB Milling 37µm cutting tool 10µm gears on silicon 25µm channel on diamond 39µm channel on graphite
