Generator for igniting plasma in a plasma chamber
A recently filed patent (Publication Number: US20230290612A1) describes a generator for igniting a plasma in a plasma chamber. The generator includes an ignition profile generator that receives a specification for voltage as a function of time and creates an ignition profile based on this specification. The ignition profile is stored in an ignition profile datastore and applied to the output of the generator using a waveform generator.
The patent also mentions that the ignition profile datastore can include test profiles, and an ignition feedback module is included in the ignition profile generator to identify the ignition voltage when the test profiles cause ignition. These test profiles consist of data points that cause the waveform generator to apply a changing voltage to the output until ignition occurs.
The waveform generator in the generator can be either a linear amplifier or a switch-mode amplifier.
Another aspect of the patent describes a non-transitory processor-readable medium that contains instructions for igniting a plasma in a plasma chamber using the generator. These instructions include receiving a specification for voltage as a function of time, creating an ignition profile based on this specification, storing the ignition profile in an ignition profile datastore, and applying a waveform with the ignition profile to the generator's output.
The non-transitory processor-readable medium also includes instructions for applying a changing voltage with the generator to the output in order to identify an ignition voltage that is less than the maximum voltage of the generator. The instructions for creating the ignition profile involve receiving a voltage value and a time value for each data point to create a waveform that jumps to the ignition voltage and then dithers about it.
Overall, this patent describes a generator that utilizes an ignition profile to ignite a plasma in a plasma chamber. The generator includes a waveform generator and an ignition profile generator, and can be used with either a linear amplifier or a switch-mode amplifier. The patent also mentions the use of test profiles and an ignition feedback module to identify the ignition voltage. Additionally, a non-transitory processor-readable medium is described that contains instructions for using the generator to ignite a plasma.
