Although a semiconductor chip is as small as the size of a human fingernail, there are a huge number of components such as transistors and capacitors and complex circuits connecting them. In order for all of these to work normally, it is necessary to create a path through which electrons can move smoothly. These passages are the metal wiring inside the semiconductor, and the process of making it is called a metal process.
The core of the metal process is to facilitate the movement of electrons so that the semiconductor chip can perform optimally. To do this, it is necessary to be able to deposit metal uniformly on fine and complex circuits. In this way, the metal process can be compared to the work of smoothing the roads for various branches in one village so that the residents can move smoothly. So, shall we go to a metal-processed restaurant that makes the semiconductor village peaceful today?
