    Abstract: The present invention relates to an apparatus and method for forming a plasma in the exhaust line of a primary process reactor. The plasma is generated in an inductive source (5) to examine the chemical concentrations of the waste or exhaust gas in vacuum lines that are below atmospheric pressure. The optical radiation emitted by the plasma is analyzed by an optical spectrometer (9) and the resulting information is used to diagnose, monitor, or control operating states in the main vacuum vessel.

    Abstract: Aspects of the present invention provide novel methods and devices for sampling gas, exciting the sampled gas to emit radiation and detecting in real time from the emitted radiation a plurality of wave bands of an emission spectrum. Energy used to excite the sampled gas may be adjusted based on the detected wave bands. A process may be controlled in real time based on the detected wave bands. Novel interfaces may be used to display portions of the detected wave bands. A known flow of a reference gas may be included in the flow of sampled gases and an unknown flow of an unknown flow gas determined.

    Abstract: An apparatus and method for programmable lock detection and correction (PLDC) to a programmable accuracy in a digital delay-locked loop (DLL) based multiphase clock generator (MCG) is based on a DLL that utilizes a digital count to control the delay of a digitally controlled, multiple-tap delay line in its feedback path where stability of the digital count is used to qualify the determination of lock to a programmable accuracy and lock determination is based on combinatorial evaluation of the multiple phase outputs for the proper waveform relationships. The incidence of false lock corresponding to excessive delay through the delay line is addressed by a LOOPRESET signal that results in a reset of the digital count that controls the delay through the delay line. Additionally, programmability of the stability interval, the digital counter step size, and the accuracy of the lock provide control over lock acquisition time.

    Abstract: The present invention relates to monitoring chemicals in a process chamber using a spectrometer having a plasma generator, based on patterns over time of chemical consumption. The relevant patterns may include a change in consumption, reaching a consumption plateau, absence of consumption, or presence of consumption. In some embodiments, advancing to a next step in forming structures on the workpiece depends on the pattern of consumption meeting a process criteria. In other embodiments, a processing time standard is established, based on analysis of the relevant patterns. Yet other embodiments relate to controlling work on a workpiece, based on analysis of the relevant patterns. The invention may be either a process or a device including logic and resources to carry out a process.
