Description

【Technical field】 [0001] The invention relates to a diamond semiconductor preparation device and a preparation process, belonging to the field of diamond semiconductor processing. 【Background technique】 [0002] The semiconductor industry has always been concerned by many fields, because many high-end devices need to be applied to semiconductors. In recent years, diamonds have gradually emerged in the semiconductor industry to use diamond as a material to make semiconductors. The industry also calls it "ultimate level". "Semiconductor", this is due to the excellent semiconductor properties of diamond, which is one of the broad-band semiconductor materials with great application prospects. It has an indirect band gap and a forbidden band width of 5.47eV. When heated, due to thermal excitation, the probability of electrons in the semiconductor transitioning from the valence band to the conduction band increases, and the conductivity of the semiconductor also increases.

Problems solved by technology

[0003] However, diamond semiconductors also have certain disadvantages, that is, the cost is high, and diamond semiconductors are different from ordinary diamonds. The electrical conductivity of the diamond semiconductors produced is also a very important indicator. Pressing process, using a multi-faceted press to extrude the material to form the finished diamond semiconductor

[0004] At present, the production process of this kind of top pressure production equipment is only to extrude diamond semiconductors into cubes, but the conductivity of the diamond semiconductors after the final production is not clear. The conduction performance test makes it necessary to add some steps before the final product, and sometimes if the conductivity of the detected diamond semiconductor is not up to expectations, it may need to be re-made, serious or even directly scrapped. This yield rate is too high. Low problem, which undoubtedly greatly increased the production cost, which made the original expensive basis even more obstacles
