The Technology That Revolutionized Surface Treatment

In the history of the world, certain inventions help to revolutionize processes. These inventions help many industries to make their processes better and improve efficiency. The technology will help the industry to speed up their processes, thus improving their productivity. There are also new technologies that will help industries to reduce their production cost. If there is one technology that has helped many industries to improve productivity and reduce the production cost, it is plasma technology. The technology has come as a great help to many industries like semiconductors, electronics, pharma, printing and automotive. Wherever there is a need for cleaning or altering a surface without changing the properties of the material is required, plasma technology is the best one to use. Polymer removal using plasma is one of the methods that has greatly helped the PC and semiconductor industries.

How Plasma Helps In Polymer Removal

The plasma cleaning process is used to remove the polymer from the surface of the object. Plasma is ionized gas and this can be safely used to remove the remaining polymer without affecting the surface of the object in any other way. The advantage of using plasma for this process is that it doesn't have the ill effects of using chemicals. Chemicals can affect the material and can be difficult to be disposed of. Plasma is a safe method with no danger to the environment. It is also an accurate way to remove polymers because it can reach every part of the surface.

While ions can reach only the bottoms of the channels, plasma can reach the corners of straight sidewalls where the polymer will not be completely cleaned. Plasma ensures the complete cleaning of the channels so that further bonding can be stronger. The most popular kind of plasma used for polymer removal is Oxygen. Other gases are also used depending on the polymer to be removed. The rate of removal of the polymer will depend on the gas being used. In the IC industry, high-performance polymers are used because of the need for them to remain stable and not reach with other chemicals or gases.

Understanding Photoresist Polymers And Their Uses

Photoresist polymer is used to mask portions of photosensitive materials to avoid those portions from being affected by the light applied to it. Though they are used in various industries like the PCB industry, printing industry and MEMS industries, the maximum usage of these materials is found in the integrated circuit industry. ICs are the reason why we have smaller and more efficient electronic appliances and computers. They also add to the speed of the process in the computers. ICs like microprocessors and computer chips are something that the world cannot live without now.

A photoresist is used to coat material and then expose it to light in a particular pattern. The photoresist is changed according to the exposed pattern. There can be both positive and negative changes. Either the resist becomes soluble in the solvent or resistant to the solvent. Depending on this pattern is etched on the material when it is dipped in a solution. With the invention of the plasma technology, the etching is done using plasma technology which will react with the photoresist more quickly and accurately. This will improve the etching profile and also ensure that the other portions of the material are not affected. A photoresist must be able to form a thin coating over the surface of the material. It must also be reactive to light which is the main use.

Understanding Plasma Technology And Its Use

Plasma is also a state of matter like solid, liquid and gas. But it is not as stable as the other three forms. When extra energy is applied to gas it turns into plasma. Lightning is one form of plasma that we commonly see around us. Being unstable it easily reacts with other materials that get exposed to plasma. The main thing is that when a material is exposed to plasma it changes the surface energy of the material. This change has various uses in different industries. This modification of the surface properties can help in various ways. The change can increase the bonding of the material to other materials.

The main advantage of using plasma to change the surface properties is that it can act just on the surface without changing the material in any other way. This makes plasma technology useful in a variety of industries. Many industries need two dissimilar materials to bond. There are industries where steel is required to be attached to glass or plastic. This bonding can be easily done with plasma technology. Plasma will change the wettability of a surface.
