Plasma - a new technology for wire annealing and wire cleaning

摘要

Today, plasma is found in a vast range of applications, from light tube to laser, from welding to special coatings applications such as the production of cutting tools or surgical implants. Semiconductor technology benefits greatly from plasma technology as well. It is the ability to focus plasma on a small area and reproduce it under the same condition that allows manipulation with small chip structures (micro structures). Plasma based etching, coating and material manipulation processes allow chips to become smaller by orders of magnitude. Plasma is ionised gas. We are used to imagining gas as free atoms and molecules chaotically flying through space. We can generate plasma by inducing energy into gas, to the extent that some atoms break into ions and electrons. This is what happens when we light a matchstick - the flame is excited gas or plasma.
