The invention relates to a device for generating a plurality of clock signals or high-frequency signals. The devices includes a reference signal generator, which is connected to an oscillator and generates at its output a reference signal with a reference frequency fx. The device also includes at least one signal processor, for example, a DDS, which is connected to the reference frequency generator via a first signal line and to which the reference signal with the reference frequency fx is supplied, and which is configured to generate an output signal having a frequency less than fx.

Generating a plurality of clock signals or high-frequency signals

A method for producing an arc detection signal on the basis of a plurality of observation signals comprises producing an arc detection part-signal for each of at least two observation signals. Producing each of the part-signals includes correlating the respective observation signal with a correlation signal by influencing the correlation signal with the respective observation, thereby producing a correlation result; producing or modifying a coefficient on the basis of the correlation result; and weighting the respective observation signal with the coefficient. The arc detection part-signals are added to form the arc detection signal.

A method of maintaining a supply of power to a load comprising operating a power generator connected to a mains voltage in a rated operating mode, generating a power signal by the power generator, feeding the power signal to the load, monitoring the mains voltage or a variable derived therefrom for an occurrence of a first specified event, and operating the power generator in a first predefined operating mode based on the occurrence of the first specified event, wherein the first predefined operating mode differs from the rated operating mode.

An arc discharge detection device is used for detecting arc discharges in a plasma process. The arc discharge detection device includes a comparator configured to emit an arc discharge detection signal and receive an instantaneous value of the signal or a signal proportional thereto, a minimum or maximum value detection device configured to receive the signal and to determine a minimum or maximum value of the signal within a predetermined time period, a setting means configured to receive the minimum or maximum value and to generate a reference signal from the minimum or maximum value, such that the reference signal is supplied to the comparator, and such that the comparator changes the signal level of the arc discharge detection signal when the comparator detects that the instantaneous value has reached the reference signal.

Method of detecting arc discharge in a plasma process

For driving at least two HF power generators that supply a plasma process with HF power, at least one drive signal is generated and at least one pulse signal is generated. Then, based on the at least one drive signal and the at least one pulse signal, a pulsed HF power signal is generated by each of the at least two HF power generator.

A plasma process power delivery system includes one or more event-ascertaining devices within the plasma process power delivery system, a controller in communication with the one or more event ascertaining devices, a first memory, a second memory, a data transmission connection, and a plasma process monitoring system. The data transmission connection is between the first memory and the second memory and is configured to transmit data relating to the plasma process power delivery system between the first memory and the second memory in response to an occurrence of a predefined event ascertained by one or more event-ascertaining devices. The plasma process monitoring system is in communication with the second memory and analyzes circumstances associated with the event that triggers the storage in the second memory using the data stored in the second memory.

An arc discharge detection device is used for detecting arc discharges in a plasma process. The arc discharge detection device includes a comparator to which an instantaneous signal and a reference value are supplied. The reference value is formed by a setting means from an extreme value of the signal. The extreme value is determined by an extreme value detection device within a predetermined time period, and the comparator changes the state of an arc discharge detection signal when the comparison between the reference value and an instantaneous value of the signal shows that an arc discharge has occurred.

Generating drive signals of at least two RF power generators which supply RF power to a plasma process, in which at least two drive signals, each driving one RF power generator, are generated in an RF generator driver. Each drive signal is generated by a respective function generator, such as a digital sine generator, of the generator driver.

A method of generating an output DC voltage of a gas discharge process voltage supply unit, in which in a first voltage transformation stage a first DC voltage is transformed into a second DC voltage of a predetermined voltage range, and the output DC voltage is generated from the second DC voltage in a second voltage transformation stage. A switching element of at least one boost converter is switched with a controlled pulse-duty factor for generating the output DC voltage in the second voltage transformation stage. This method permits striking and maintenance of a plasma process.

A current supply system includes one or more, or a plurality of current supply modules that each includes an input terminal and an output terminal and that each has a maximum output power. Multiple current supply modules are electrically combined to form a current supply unit having a maximum output power that is greater than the maximum output power of the individual current supply modules, and a control unit is connected to the current supply unit. A data connection connects the control unit to all the current supply modules of the current supply unit.
