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 [...]
The role of hydrogen in the energy transition The role of hydrogen in the energy transition - Cheersonic Both hydrogen energy (green hydrogen) and electricity (green electricity) are secondary energy sources, which are inevitable choices under the dual-carbon goal strategy. The utilization of hydrogen has a long history, but it is not in the fields of transportation and power that are currently attracting attention, but is mainly used [...]
Hydrogen energy development will affect various industries Hydrogen energy development will affect various industries - Cheersonic In the process of accelerating the energy transition, hydrogen energy is expected to be fully integrated into all fields of the energy demand side. In the industrial field, hydrogen energy will be "two-pronged" from raw materials and energy. In terms of raw materials, hydrogen energy will be widely used in steel, chemical, [...]
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 [...]
Electrolyzer At present, driven by both policies and markets, the hydrogen energy industry chain is developing rapidly, which has also led to the rapid growth of hydrogen production; and the proposal of the dual-carbon goal has made "green hydrogen" an important way to reduce carbon and decarbonize. Among them, hydrogen production from water electrolysis is an important method for producing green hydrogen. The increase in the scale of [...]
Semiconductor Wafer Production Process Semiconductor Wafer Production Process - Cheersonic The production process of semiconductor silicon wafers is long and involves many processes. The production process of semiconductor polishing wafers includes crystal pulling, spheronization, cutting, grinding, etching, polishing, cleaning and other processes; the production process of semiconductor epitaxial wafers is mainly epitaxial growth on the basis of polishing wafers; SOI silicon wafers mainly use bonding or ionization injection, [...]
Semiconductor materials silicon-based and silicon carbide-based Semiconductor materials silicon-based and silicon carbide-based - Cheersonic In the field of power semiconductors, the main materials are silicon and silicon carbide, etc. First look at the silicon base. The global semiconductor wafer industry has a high market concentration, mainly occupied by well-known companies from Japan, Germany, South Korea, Taiwan, and other countries and regions. At present, the world's top five semiconductor [...]
Electronics Industry Forecast for 2022 After going through the twists and turns of 2021, the entire electronics industry has officially entered 2022. Although many analysts said that the shortage of chips that the electronics industry has suffered in the past two years will continue in the first half of this year, with the concerted efforts of the industry chain, this situation will be alleviated in the second half [...]
