Abstract:
A spectroscopic rotating compensator material system investigation system including a photo array (DE's) for simultaneously detecting a multiplicity of wavelengths is disclosed. The spectroscopic rotating compensator material system investigation system is calibrated by a mathematical regression based technique involving, where desirable, parameterization of calibration parameters. Calibration is possible of calibration parameters. Calibration is possible utilizing a single two-dimensional data set obtained with the spectroscopic rotating compensator material system investigation system in a "material system present" or in a "straight-through" configuration.
Abstract:
A method of, and system for, applying light beam producing systems (7) such as ellipsometers, polarimeters, polarized light reflectance and functionally similar systems, such that a beam of light produced thereby is caused to be incident upon a process element (4) at an angle in excess of an associated Brewster angle while enabling the production of a signal sufficiently sensitive to changes in process element parameters, for use in "real-time" process element process monitoring and control, is disclosed. In addition a process element processing system (1) and electron beam producing system and light beam producing system combination system is taught, wherein the electron beam producing (2) and light beam producing (7) systems are mounted to the process element processing system (1), (typically a (MBE) system), by input and output interface systems (9I) (9O) present at a location appropriate for conventional Reflection High Energy Electron Diffraction (RHEED) systems.
