摘要:
The temperature measuring system using optical interference includes a light source which generates measuring light; a spectroscope which measures an interference intensity distribution that is an intensity distribution of reflected light; optical transfer mechanisms which emit light reflected from a surface and a rear surface of the object to be measured to the spectroscope; an optical path length calculation unit which calculates an optical path length by performing Fourier transformation; and a temperature calculation unit which calculates a temperature of the object to be measured on the basis of a relation between optical path lengths and temperatures. The light source has a half-width at half-maximum of a light source spectrum that satisfies conditions based on a wavelength span of the spectroscope. The spectroscope measures the intensity distribution by using the number of samplings that satisfies conditions based on the wavelength span and a maximum measurable thickness.

A plasma processing apparatus and a temperature measuring method that may measure a temperature of an object in a processing chamber by a low-coherence interferometer without forming a hole in a holding stage or an upper electrode of the plasma processing apparatus, thereby performing a plasma process of a substrate with high precision and uniformity. The plasma processing apparatus is implemented by disposing a light source collimator outside of a light source window, disposing a light-receiving collimator outside of a light-receiving window, allowing a measurement light emitted from the light source collimator to pass through the light source window to be obliquely emitted to a surface of the object to be measured, and allowing the reflected measurement light to pass through the light-receiving window to be incident on the light-receiving collimator. The temperature of the object in the processing chamber may be measured by the low-coherence interferometer.

A probe for temperature measurement uses interference of a low-coherence light beam. The probe includes a temperature acquiring member configured to be brought into contact with a surface of a temperature measurement target and thermally assimilate with the temperature measurement target; a light irradiating/receiving unit configured to irradiate a measurement light beam as a low-coherence light beam to the temperature acquiring member and receive reflected light beams from a front surface and a rear surface of the temperature acquiring member; and a housing configured to define a distance between the temperature acquiring member and the light irradiating/receiving unit to a preset length and isolate optical paths of the measurement light beam and the two reflected light beams from an atmosphere in which the temperature measurement target is placed.

A method and system for modifying a gate dielectric stack by exposure to a plasma. The method includes providing the gate dielectric stack having a high-k layer formed on a substrate, generating a plasma from a process gas containing an inert gas and one of an oxygen-containing gas or a nitrogen-containing gas, where the process gas pressure is selected to control the amount of neutral radicals relative to the amount of ionic radicals in the plasma, and modifying the gate dielectric stack by exposing the stack to the plasma.

A capacitive coupling plasma processing apparatus includes a process chamber configured to have a vacuum atmosphere, and a process gas supply section configured to supply a process gas into the chamber. In the chamber, a first electrode and a second electrode are disposed opposite each other. The second electrode includes a plurality of conductive segments separated from each other and facing the first electrode. An RF power supply is configured to apply an RF power to the first electrode to form an RF electric field within a plasma generation region between the first and second electrodes, so as to turn the process gas into plasma by the RF electric field. A DC power supply is configured to apply a DC voltage to at least one of the segments of the second electrode.

A capacitive coupling plasma processing apparatus includes a process chamber configured to have a vacuum atmosphere, and a process gas supply section configured to supply a process gas into the chamber. In the chamber, a first electrode serving as a cathode electrode, and a second electrode grounded to serve as an anode electrode are disposed opposite each other. An RF power supply is disposed to supply an RF power to the first electrode to form an RF electric field within a plasma generation region between the first and second electrodes, so as to turn the process gas into plasma. The target substrate is supported by a support member between the first and second electrodes such that a process target surface thereof faces the second electrode. The second electrode includes a conductive counter surface facing the first electrode and exposed to the plasma generation region.
