B-11
天然硼元素有兩種穩(wěn)定同位素，即10B和11B，相對(duì)豐度分別為19.78%和80.22%。11B質(zhì)子數(shù)為5，中子數(shù)為6，與10B不同，11B對(duì)熱中子的吸收截面僅為0.005靶。天然硼或硼化合物作為半導(dǎo)體器件制程摻雜源使用時(shí)由于引入10B一起進(jìn)行摻雜，在某些特定使用環(huán)境會(huì)對(duì)半導(dǎo)器件性能造成致命的影響，輕則影響電子設(shè)備運(yùn)行速度，重則導(dǎo)致死機(jī)甚至毀機(jī)。因此11B被用于半導(dǎo)體器件制程的摻雜劑，能夠有效提高器件的半導(dǎo)體性能和抗輻射抗干擾能力。此外，11B還可用于特種鋼材制造行業(yè)，用于提高材料的耐高溫和耐輻射性能。
Natural boron has two kinds of stable isotopes, 10B and11B, with relative abundance of 19.78% and 80.22%, respectively.11B has five protons and six neutrons. Unlike 10B, 11B has an absorption cross section of only 0.005b for thermal neutrons. When natural boron or boron compound is used as the dopant of semiconductor devices, the introduction of 10B will cause fatal impact on the performance of semi-conductor devices in certain specific use environment, which may affect the running speed of electronic devices, or even lead to destruction of the machine. Therefore, 11B is used as a dopant in the process of semiconductor device manufacturing, which can effectively improve the semiconductor performance and anti-radiation and anti-interference ability of the device. In addition, 11B can also be used as an additive to the steel used in the manufacture of reactors, which can greatly improve the resistance to high temperature and radiation.
11B可以應(yīng)用在半導(dǎo)體行業(yè)，用11B作為摻雜劑可以使得硅離子布植緊密，從而生產(chǎn)高度集成、高密度的微型芯片，且提高半導(dǎo)體器件的抗輻射干擾能力。11B也可以作為鋼材的添加劑，這種鋼材用于制造反應(yīng)器，可以使反應(yīng)器的耐高溫、耐輻射性能得到大幅度提高。
As a dopant, 11B can be applied in the semiconductor industry, which makes silicon ion layout closely, so that the highly integrated and high-density microchips can be produced. 11B can also be used as an additive to the steel used in the manufacture of reactors, which can greatly improve the resistance to high temperature and radiation.
