The invention relates to a circuit for the automatic evaluation of the electrical wave time course in a plasma chemical etching process. In the plasmachemical etching of semiconductor structures in the production of microelectronic elements it is necessary to objectively observe the technological process and determine the moment of its completion according to a certain symptom. For this purpose, various types of plasma-chemical etch transducers are used which transform the characteristic parameters of the chemically active plasma, such as the pressure, the intensity of the radiation of a suitable selected spectral line or the spectral region at3, to the electrical signal. The etching time is determined by the characteristic change in the electrical signal of the transducer during the etching process. The automation of the technological process of plasma chemical etching requires that the characteristic change of the electrical signal, which represents the symptom of the end of the technological process, can be evaluated electronically with the required accuracy. So far, the methods and connections used for signal evaluation by level using comparator circuits are only applicable when the signal change is sufficiently large when the absolute signal size is reproducible with average accuracy. However, in many technological processes of plasma chemical etching, the sensed electrical signal does not sleep "some of the criteria when its changes are relatively small, the absolute value of the signal is not reproducible, the time course is not monotonous and the like. In practice, the evaluation of signaling processes has been avoided since the automation of the respective cracking processes, but some of the drawbacks of this are the low noise and fast changing interference disturbances, but none of these solutions are suitable for non-monotonous changeover signals. the drawbacks are eliminated by the connection for the autmoatic evaluation of the time course of the electrical signal in the process of plasma chemical etching according to the invention, the principle of which is that the signal input terminal is connected via a signal amplifier by an incremental amplifier whose signal output is connected to a signal input of a differential circuit with a logic output coupled to a second logic input of the control circuit. Its first logical output is coupled to the incremental amplifier blocking input, and the second logic output is connected to the incremental amplifier control input, the third control circuit logic output is coupled to the differential circuit activation input, and the fourth logic output is coupled to the first timing input a circuit whose output is coupled to the output terminal. The logic output of the incremental amplifier is connected to the first logic input of the control circuit, the output of the first timing circuit is connected to the fourth logic input of the control circuit, the input of which is together with the logic input of the control circuit and the second input of the second timing circuit connected to the logic input terminal. The advantage of the circuitry according to the invention is that it makes it possible to eliminate the influence of an absolute large-scale signal, to accurately detect very small changes, up to 1%, and to evaluate its shape. The connection allows unambiguous and precise determination of the etching process termination by combining the signal change evaluation against its extreme and evaluating the signal's time dependence. Differential method estimation of signal time dependence substantially improves evaluation resistance against noise and random failures. A further advantage is the possibility of processing a signal with a complex time-dependent structure in that the evaluation process can be decomposed into simpler stages within which a unique identification of the characteristic signs can already be performed, wherein the unrepresentative and undesirable signals can be completely excluded from the processing. The equipment of the percent etching additional time takes into account the changes in the etching rates of the molded layers in different manufacturing batches. The device according to the invention provides for the automation of the etching process. At the beginning of the technological process, the wiring is automatically activated, during the process it allows to detect the flag of its termination and after the additional etching time elapses, a command to automatically shut down the technological process is generated.
