Silicon is a very interesting chemical element. Although it is the "little brother" of carbon in the periodic and its activity is not as powerful as its "big brother", silicon element is widely present in nature, the most common being sand! As a part of the vast ocean sand, at room temperature, silicon element is very stable when combined with its old partner, oxygen. Moreover, pure silicon or industrial silicon that has been melted and solidified is also extremely mild-mannered, with a main feature of having no temper! However, beneath its quiet appearance lies a restless heart. Especially at high temperatures, its character becomes passionate unrestrained, and liquid silicon can react with all metal oxides, silicates, and aluminates to do incredible things—reactions! And it forcibly takes the oxygen these compounds. Sometimes, even without the presence of its old friend oxygen, it can become a close partner with this more stable element, Si3N₄, after being given enough in nitrogen. After having a preliminary understanding of the silicon element's character, which seems mild but can become passionate under certain conditions, it is not difficult to understand its semiconductor. What remains unchanged is always changing, which is a vivid description of it. Its conductivity is between that of a conductor and an insulator, and this unpredictable character has many good friends creating a harmonious atmosphere. As the temperature increases, the conductivity of silicon will increase, and vice versa, it may become lazy! Such a "unique" character, however exists as the "big brother" in the application field. In the field of chip manufacturing, silicon is the industrial base material for semiconductors. At 2000, the silicon element makes itself extremely delicate, and as an atomically flat wafer, it makes one suspect that the silicon element has a very serious "obsessive-compulsive"! However, this "obsessive-compulsive disorder" ultimately becomes a fingernail-sized chip with extraordinary functionality after going through processes such as photolithography, etching, and ion implantation! Speaking of this, I suddenly realized that our understanding of the character of the silicon element at the beginning was somewhat misguided. In situations, it really embodies multiple personality characteristics! There are too many such examples. High-quality optical instruments are inseparable from its existence, and advanced optical sensors and highspeed communication are mainly its credit. In our lives, artificial joints and tooth materials, especially silicon hydrogel lenses, the silicon element plays a crucial role as a key existence with multiple, and it has played an essential role! Silicon is very interesting, and what we are doing now is to let the interesting silicon element play a greater role in contact lenses We have the same "obsessive-compulsive disorder" as silicon element for the purity and requirements of products, we have the same pursuit of product quality as silicon element, we also have the same inclusive corporate culture as silicon element. Let this silicon element be a bridge, let us form the strongest covalent bond with all walks of life inside and the industry!
