Patent ID: 8719960

Claim:
A device for measuring or controlling temperature-dependent electrical properties of a surface comprising: a. a cantilever having a fixed end and a free end, said cantilever comprising single crystal silicon; b. a heater-thermometer positioned near said free end of said cantilever, wherein said heater-thermometer comprises a thermistor comprising doped single crystal silicon; c. a conductive tip electrode for measuring or controlling a voltage between said conductive tip electrode and said surface or for flowing a current between said conductive tip electrode and said surface, said conductive tip electrode positioned near said free end of said cantilever, wherein said conductive tip electrode is electrically isolated from said heater-thermometer; d. a layer of insulating material positioned to provide electrical isolation between said conductive tip electrode and said heater-thermometer; and e. one or more single crystal silicon electrodes electrically connected to said heater-thermometer or said conductive tip electrode, wherein said one or more single crystal silicon electrodes comprise one or more legs of said cantilever.
