Thereafter B-A1 paste-layer diffusion technology and close-tube Ga-diffusion technology had been developed, while the former can lead to relatively large the base-region deviation and abruptly varied region in Si, which caused severe decentralization of current amplification parameter β, bad thermal stability and high tr; the latter needed the relatively difficult pack technique, with poor repeatability , high rejection ratio, and poor diffusion quality and production efficiency.

此工艺发明以来，克服了上述两者的弊端，杂质浓度和结深能准确控制而又能任意调整，可进行低、高浓度阶段性掺杂，得到元素Ga在Si中的理想分布，而且表面浓度均匀一致、重复性好、合格率和优品率高，改善和提高了器件的综合性能。

However, in 2007 the American pet food pollute affairs of the initial inquisition thinks as a result:Blended ≤ 6.6% three gather cyanotype An of the wheat egg white powder is a pet food to cause poisoned reason, ascended question mark for the above-mentioned toxicity slight conclusion painting.
