As a kind of power generation device that converts chemical energy in hydrogen and oxidant into electricity, the gas tightness of fuel cell stack is very important. This is the test of VET for the ...
It is very inaccurate to say that graphite is a semiconductor. in some frontier research fields, carbon materials such as carbon nanotubes, carbon molecular sieve films and diamond-like carb...
The manufacturing of each semiconductor product requires hundreds of processes. We divide the entire manufacturing process into eight steps: wafer processing-oxidation-photolithography-etching-thin...

1. Third-generation semiconductors
The first-generation semiconductor technology was developed based on semiconductor materials such as Si and Ge. It is the material basis for the development of tr...
After the ceramic substrate is sintered and formed, its surface needs to be metallized, and then the surface pattern is made through image transfer to achieve the electrical connection performance ...
