Plasma treatment

Uncompromisingly pure by using plasma

Plasma technology has further areas of application in industrial production in addition to plasma coating and plasma etching. Workpiece surfaces then require only modification rather than removal or coating. Cleaning:
Workpieces in metal processing previously underwent fine cleaning using CFCs. An alternative for surface cleaning is to use the extremely high reactivity of a gas excited in plasma. Organic residues, for example, can be fully removed using oxygen. Surface activation:
Plasma treatment can chemically modify the inert surface of a workpiece so that color coatings adhere without needing a special primer. This process is particularly practical for the diversity of plastic component designs. Plasma diffusion:
Steel workpiece surfaces often require hardening and corrosion protection. This can be achieved in the plasma simply by nitriding, boriding, or carburizing.

It depends on the form: bipolar sputtering
Two characteristics of bipolar power supplies are presented in this article: (i) a wide pulse frequency range of up to 100 kHz and (ii) an additional brake time between the positive and negative half-wave of the square wave shape of electricity and voltage.

Auto Frequency Tuning
A countermeasure against rapid fluctuations in the plasma's impedance range is automatic frequency tuning, during which the RF generator sets its fundamental oscillation to a frequency value with better adaptation within a time frame of less than one millisecond.

New pulsed DC technology
Direct current and pulsed direct current sputtering are some of the most frequently used sputtering techniques in the industrial sector. The introduction of pulsed direct current technology facilitated the mass production of coatings made of non-conductive compounds created by reactive magnetron sputtering.

Application of pulsed DC sputtering
One of the most interesting resorption materials for solar cells are copper-indium-selenide (CIS) based materials whose properties can be changed by replacing a part of the indium with gallium to make Cu(In,Ga)Se2, known as CIGS.

Precision in processing
Continuous improvements to the semiconductor production process are required to ensure a continuous reduction in size. This in turn requires TF generators that have an ever-higher signal quality in relation to output power and time resolution.
