Verfahren zur Erzeugung eines Plasmas durch Einstrahlung von Mikrowellen

Номер: DE0019740792A1
Принадлежит:

The invention relates to a method for producing plasma by microwave irradiation, wherein a process gas is conducted into a container and a plasma is ignited by means of microwave irradiation. According to the invention, the injected microwave radiation is pulsed. This enables the same process result to be obtained at lower effective microwave output so that the process temperature can be scaled down. The process rate can also be increased at effectively the same injection output, thereby reducing process time and increasing charge quantities to a considerable degree.

Electron cyclotron resonance apparatus

Номер: DE0004403553A1
Принадлежит:

A electron cyclotron resonance apparatus which is capable of producing a cryogenic cooling effect. As a result of a radioactive movement (motion) property of radicals, a side-wall etching of a photoresist can be prevented during the production of integrated micropatterns of the next generation. The apparatus also eliminates mutually contradictory growth/reduction phenomena which arise between the etching rate and the anisotropy as well as between the etching rate and the uniformity of the general etching devices. This not only achieves a desired vertical etching but also a rapid etching rate. It is thus possible to eliminate factors which create a complexity in the process, to be specific by using a conventional three-layer P/R (TLR) or a multi-layer P/R (MTR), and which adversely affect the yield and the productivity.

The known processes require a considerable amount of apparatus for low-pressure glow discharges in order to distribute the generator output to the two electrodes and to control it statically and dynamically. Up until now it has not been possible to achieve this control for high energies and over a great range of frequencies. A process variable measured in-situ should be controllable and adjustable. According to the invention, the direct voltage is produced by means of a four-quadrant d.c. power supply. For this the d.c. power supply is decoupled on the alternating voltage side and connected with one pole to the alternating power supply and with the other pole to an electrode of the bipolar glow device. The direct voltage is set dependent upon a process variable of the glow discharge so that a specific ratio in the power distribution between the two electrodes results. The invention is applicable in plasma treatment of surfaces, deposition of coatings from the plasma and plasma enhanced ...
