  • Patent number: 5731587
    Abstract: A hot stage for a scanning probe microscope includes a substrate having a dielectric window region which is stress compensated to be held in mild tension at elevated temperatures. A heating element is supplied to heat a specimen deposited on the dielectric widow region and the scanning probe microscope is used to observe specimen characteristics at the elevated temperatures. The dielectric window region is configured to be thermally isolated from the rest of the hot stage allowing only a minimum amount of heat to be dissipated into the scanning probe microscope. Temperature sensing resistors are included for monitoring the temperature in the dielectric window region. Conductivity cell electrodes can also be included for sensing the conductivity and capacitance of the specimen. Furthermore, additional control and measurement hardware, such as a temperature sensor circuit, evaluation station, the ramp generator circuit, etc. can be included to provide additional system features.

  • Patent number: 5296255
    Abstract: A method for selectively forming thin films by CVD in which at least two substrates are exposed to a decomposable gas, and one of the subsrates is independently heated to selectively form a film on the heated substrate. The invention further comprises a step of measuring an electrical property of the film during deposition.
