What Is The Etching Process? What Is The Etching Process - Ultrasonic Coating Systems - Cheersonic Etching is a technique that uses chemical strong acid etching, mechanical polishing or electrochemical electrolysis to treat the surface of objects. Apart from enhancing the aesthetics, it also increases the added value of the object. From traditional metal processing to high-tech semiconductor manufacturing, etching technology is within the scope of application. Etching [...]

What is metal etching? Etching is a technique that uses chemical strong acid etching, mechanical polishing or electrochemical electrolysis to treat the surface of objects. Apart from enhancing the aesthetics, it also increases the added value of the object. From traditional metal processing to high-tech semiconductor manufacturing, etching technology is within the scope of application. Metal etching is a technique for removing metallic materials through chemical reaction or [...]

Moore's Law has come to an end? Looking at Moore's Law in 2022, the problem is that the size of transistors is now so small that we can't do more to make them smaller. A silicon atom is 0.2 nanometers wide, which makes a gate length of 2 nanometers about 10 silicon atoms. At these scales, it becomes increasingly difficult to control the flow of electrons as various [...]

The History of Transistors A transistor is a semiconductor that typically has at least three terminals that can be connected to a circuit. Typically, one of the terminals is responsible for controlling the current through the other two terminals, which allows fast switching in digital circuits. Before transistors, this fast circuit switching was done using thermionic valves, often referred to as old-fashioned vacuum tubes. These vacuum tube triodes [...]

Chip shortage in the medical industry Medical chips are in a hurry, and the cost doubling is "troubling" The integrated circuit chip is to shrink and shrink a large electronic module. For electronic products, the chip is equivalent to the brain. "Generally speaking, according to different application scenarios, chips can be divided into commercial grade, industrial grade, automotive grade, etc. For the medical industry, the selection of available [...]

Global Chip Shortage In June 2021, a "big chip robbery" occurred in Hong Kong. A logistics company robbed 14 boxes of chips worth about HK$5 million in transit. There is a rumor circulating in the circle: in this case, the person who grabbed the core was actually the buyer. The reason is that the seller temporarily sits on the ground to raise the price, and the buyer finds [...]

Si-based and SiC-based manufacturing contamination issues Si-based and SiC-based manufacturing contamination issues - Cheersonic First look at the pollution of silicon-based production. Many links in its production and operation involve environmental pollution, and a certain amount of waste water, waste gas, solid waste and noise will be generated during the production process. Waste water includes process waste water and waste gas treatment system waste water, and a certain [...]

Silicon-based and silicon carbide-based comparison Silicon-based and silicon carbide-based comparison - Cheersonic The first, second, third, and fourth generations of semiconductor materials have their own advantages and disadvantages, and there is no absolute substitution relationship, but they have their own comparative advantages in specific application scenarios. This should be established as a common sense perception. Performance comparison of the following materials: Silicon is a semiconductor material, and its [...]

SiC-based production process of power semiconductors SiC-based production process of power semiconductors - Cheersonic It can be divided into the following steps: (1) Raw material generation: (PVT gas phase formation, many structures, difficult to control) The high-purity silicon powder and high-purity carbon powder are uniformly mixed according to the process formula, and at a high temperature above 2,000 ℃, a specific reaction process is carried out in the [...]
