Abstract: PURPOSE:To make the characteristic of a shoulder of a trap characteristic steep by providing an inductor on a trap circuit so as to form the impedance characteristic of the circuit viewing an output terminal as if another parallel resonance frequency were caused to a lower frequency band than the resonance frequency of the resonator apparently. CONSTITUTION:A resistor 6 and an inductor 12 are connected in series between an input terminal 2 and an output terminal 4 and a resonator 8 and a resistor 10 are connected in parallel between the output terminal 4 and ground. Thus, another parallel resonance frequency seems to be formed to a lower frequency than the resonance frequency of the resonator 8 apparently, and the characteristic of a shoulder A in the trap characteristic is made steep by the parallel resonance. Moreover, the characteristic of the shoulder A is adjusted by selecting properly the inductance of the inductor 12 and the resistance of the resistor 6 so as to make the characteristic of the shoulder A slow or steep in the trap characteristic.

Title: Method for etching semiconductor layer
IPC: H01L21/306
Filed: 1992-03-10
Abstract: PURPOSE:To make it possible to end an etching immediately after a desired semiconductor layer has been etched without time control by applying laser light to a wafer, monitoring variations in the intensity of the laser light reflected by the wafer, and thereby detecting the end of etching in the desired semiconductor layer. CONSTITUTION:A semiconductor multilayer on a wafer 1 is etched by holding the wafer 1 in etchant 3. Laser light is applied to the wafer 1 in the process above. The laser light reflected by the wafer 1 is monitored for variations in the intensity, and the end of etching in a desired semiconductor layer is thereby detected. For example, laser light is shaped into a parallel beam through lenses 5 and 6 and applied to 4 surface of a wafer 1 in etchant 3. The light reflected by the wafer 1 is guided into a photodetector 8 through a lens 7, and the fluctuation in its output is observed using a recorder 9 or the like. When the fluctuation in the optical output stops, it is judged that the etching has reached an etching stopper layer.

When the output of the level weighting circuit 12 is larger than a level V0, a comparator 35 outputs a signal to a driving circuit 37. When the output to pass through a band pass filter 13 is larger than a level Vp, a comparator 35a outputs the signal to a driving circuit 37a.
