摘要： An apparatus (295) using specular reflection spectroscopy to measure a temperature of a substrate (135). By reflecting light (100) from a substrate, the temperature of the substrate can be determined using the band-edge characteristics of the substrate. This in situ apparatus can be used as a feedback control in combination with a variable temperature substrate holder to more accurately control the processing conditions of the substrate. By utilizing a multiplicity of measurement sites, the variation of the temperature across the substrate can also be measured.

摘要： An RF electric field probe device for measuring an RF electric field intensity in a plasma. The device is composed essentially of an electric field sensing unit and an output unit. The electric field sensing unit is composed of a first electro-optical component positionable in the plasma and operable to modulate light as a function of variations of the RF electric field in the plasma at the fundamental frequency and harmonics of the RF electric field, and a first antenna unit electrically coupled to the first component for coupling the first component to the RF electric field. The output unit is coupled to the electric field sensing unit for providing an output signal containing information relating to the magnitude and frequency of the modulation which occurs in the first component. The probe device may be used to map a plasma region by moving the probe device to any selected point in the plasma region.

摘要： A system for measuring plasma electon densities (e.g., in the range of 1010 to 1012 cm−3) and for controlling a plasma generator (240). Measurement of the plasma density is essential if plasma-assisted processes, such depositions or etches, are to be adequately controlled using a feedback control. Both the plasma measurement method and system generate a control voltage that in turn controls the plasma generator (240) to maintain the plasma electron density at a pre-selected value. The system utilizes a frequency stabilization system to lock the frequency of a local oscillator (100) to the resonant frequency of an open microwave resonator (245) when the resonant frequency changes due to the introduction of a plasma within the open resonator. The amplified output voltage of a second microwave discriminator may be used to control a plasma generator (240).
