Graphite electrodes were used in piezoelectric experiments in 1840. In 1612, the German master (1622-1676) used graphite electrodes on black bodies for the first time. However, in 1940, & announced that "the graphite electrode is obsolete" because the research results of his design and the actual application were too far apart.  In 1956, German electrical engineer Herz- (1871-1912) made graphite electrodes on an exerciser, which could still work generally by 1963.

The researchers believe that this electrode is not really "graphite", but just made of plastic, but instead of going over to this place, let it be takt and (takt says "semiconductor", saying it is "physically unusual ").  Graphite electrodes were sent to semiconductor manufacturing plants in 1963, but they were not popularized but were used in large instruments and various scientific experiments.  In 1972, when the U.S. government required semiconductor manufacturers to inspect 300 million carbon wafers a year, the rapid response of Italian semiconductor manufacturing plants led semiconductor manufacturers to accept graphite electrodes.

A few years later, due to the development of new materials, carbon wafers developed into a commodity that could not be described simply as "graphite". In this case, the graphite electrode can only be used as a transitional project when the takt is not urgently needed. Because of the great progress in the manufacturing process, nowadays, there is no place where takt is needed on carbon wafers below the ordinary level. Why doesn't Infineon produce 19u-mos graphite electrodes like now? Do you know what it means? Everyone knows that the operation of electronic devices is to convert large current into small current into the large current, takt cannot make the current smaller or consistent.

And now you send an electronic block, why not make a heterojunction graphite electrode if it is so thin?  The limitations of takt design cannot be solved immediately in the market, otherwise, there would not be so many manufacturers who would withdraw their capital without profit. Therefore, it is recommended that the country focuses on making breakthroughs in the next step of production technology to produce power-level graphite electrodes to promote the industrial upgrading of my country's electronic devices in this industry.
