    摘要: A method of anisotropic etching of structures in a semiconductor body, in particular of recesses in a silicon body (18) exactly defined laterally by an etching mask, by using a plasma (28) is proposed. An ion acceleration voltage induced in particular by a high-frequency AC voltage is applied to the semiconductor body at least during an etching step having a predefined duration. The duration of the etching step is further subdivided into at least two etching segments between which the ion acceleration voltage applied is modified each time. Preferably two etching segments are provided, a higher acceleration voltage being used during the first etching segment than during the second etching step. The length of the first etching segment can furthermore be determined dynamically or statically during the etching steps using a device for the detection of a polymer breakdown. In order to generate and adjust the value of the acceleration voltage, preferably high-frequency pulses or pulse packets having an adjustable pulse/pause ratio are used.

    摘要: A device and a method for etching a substrate, in particular a silicon body, by using an inductively coupled plasma. A high-frequency electromagnetic alternating field is generated using an ICP source, and an inductively coupled plasma composed of reactive particles is generated by the action of a high-frequency electromagnetic alternating field on a reactive gas in a reactor. In addition, a static or time-variable magnetic field is generated between the substrate and the ICP source, for which purpose at least two magnetic field coils arranged one above the other are provided. The direction of the resulting magnetic field is also approximately parallel to the direction defined by the tie line connecting the substrate and the inductively coupled plasma. Finally, a first component magnetic field is generated with a first magnetic field coil, and a second component magnetic field which is equally strong at an equivalent site is generated with a second magnetic field coil, the two component magnetic fields being oriented in opposite directions.
