who belongs to the field of science and information technology knows about the silicon wafer term Ray Nitschke Packers Jersey , but the people who have not much information about science and information technology do not know what a silicon wafer is. It is very common in the field of IT, physics and chemistry. The silicon wafer processing is involved here.
Lithography is also known as art work in which printing method is used with the help of stone or a metal plate with a completely smooth surface. In the semiconductor industry, a process is used for device fabrication, a methodology that transfer a pattern from photomask to the surface of substrate that is helpful for the production of electronic component like an integrated circuit.
There are lots of steps which are involved in the production of semiconductor in the lithography process. These are the following:
The lithographer imposes the structure of light on a beam by passing it through a mask and this is followed by projecting the image into a silicon wafer coated with a thin layer of material for resistance.
The next step in this process is the chemical transformation. In this process, the resist covering the substrate undergoes a chemical transformation when exposed to light. This process alerts the solubility of materials and this alteration makes the latent pattern image into a chemical stencil after the application of an appropriate solvent.
After performing the chemical transformation process, we do deposition process. In this process, the substrate is placed inside the reactor and lots of gases are supplied with it, which create a chemical reaction and produce a solid material with condenses on all surfaces
