Abstract: The present invention relates to a method of lowering dielectric constant of an insulating film including Si, O and CH formed by a chemical vapor deposition process. A process gas containing hydrogen atoms is supplied into a reaction vessel. A microwave is introduced into the reaction vessel to supply a uniform electromagnetic wave, thereby a plasma containing a hydrogen radical is generated in the reaction vessel. The structure of the insulating film is modified by the hydrogen radical contained in the plasma irradiated to the insulating film, lowering the dielectric constant of the film. The microwave is supplied into the reaction vessel through a radial-slot antenna.

Abstract: The present invention relates to a method of measuring by a coordinate measuring instrument. A detecting element is manually moved along a sample of work to be measured in accordance with a predetermined sequence of measuring steps. A moving path of the detecting element is detected by displacement detectors which produce output signals which are inputted to a command unit incorporated in a robot mechanism for storage. Subsequently, a data processing unit gives a command to carry out an automatic measuring sequence, and the robot mechanism is moved along the stored moving path by its drive system, whereby measurement results for dimensions are calculated on the basis of data acquired during the automatic measuring due to the contact between the detecting element and the work and data stored during the manual set-up phase. The detecting element is uncoupled from the drive system of the robot mechanism during the manual set-up phase.
