The nanoscale processes are impressive. Did the original chip do that?

The emergence of semiconductors can be said to change the application of electronic products in the world, anti vibration table so that the rapid development of science and technology, and Taiwan in the world's semiconductor industry chain plays a pivotal role, with a complete and leading semiconductor industry, but how is the chip manufactured?

Commercially available chips are complicated and cumbersome to manufacture. 

To make holy bread, you must first create holy bread. semiconductor test Wafer manufacturing is divided into three stages, including design, manufacturing, and packaging. Silicon wafers are the basis for holy bread. As silicon is a semiconductor between a conductor and an insulator, its conductivity can be adjusted by adding impurities. Using columns of high-purity silicon, wafers are cut, ground, and cooled with molten silicon after they are cut.

Over the next two years, voltage probe global OEM revenue is expected to grow despite sluggish chip demand.

After the wafer is made, the coating is first oxidized by the oxidation equipment. Following that, the most complicated process is "lithography." Initially, it is coated with photoresist and then placed in a lithography machine, where the circuit diagram on the mask is reduced and projected onto the photoresist, resulting in a circuit diagram that appears on the wafer based on the desired circuit diagram.

Now, to eliminate the unused areas, proceed to the next step of "etching". This stage involves using a unique chemical solution or gas to wash away the unprotected portions under the photoresist coating. Then, another solution is used to remove the photoresist. Next, a protective layer is redeposited on the eroded oxide film through deposition technology. Additionally, ions and other impurities (such as phosphorus and boron atoms) are injected to regulate conductivity. This marks the completion of the "integrated circuit" at this stage.

Lastly, after undergoing metal filling and a series of intricate procedures, the wafer is transformed into integrated circuit chips through cross-repeat connections. This marks the end of the entire manufacturing process. The qualified products will then move on to further stages such as welding and cutting to become marketable chip products. These processes not only require great complexity and difficulty, but their nanoscale nature also evokes awe at the astounding technology behind them.
