At the initial stage of planar technique, b was employed as ideal diffusion impurity in base - region of npn si planar devices because of the match of its solid - solubility and diffusion coefficient in si with those of p in emission - region, and the good shield effect of sio2 film to b. but because of the relatively large solubility ( 5 1020 / cm3 at 1000 ) and the small diffusion coefficient, the linear slowly - changed distribution of acceptor b in pn junction can not be formed, which could not cater to the requirement of high - reversal - voltage devics. 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, 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 productio n efficiency
在平面工藝初期，由於b在硅中的固溶度、擴散系數與n型發射區的磷相匹配， sio _ 2對其又有良好的掩蔽作用，早被選為npn硅平面器件的理想基區擴散源，但b在硅中的固溶度大（ 1000時達到5 10 ~ （ 20 ） ，擴散系數小， b在硅中的雜質分佈不易形成pn結中雜質的線性緩變分佈，導致器件不能滿足高反壓的要求，隨之又出現了硼鋁塗層擴散工藝和閉管擴鎵工藝，前者會引起較大的基區偏差，雜質在硅內存在突變區域，導致放大系數分散嚴重，下降時間t _ f值較高，熱穩定性差；後者需要難度較大的真空封管技術，工藝重復性差，報廢率高，在擴散質量、生產效率諸方面均不能令人滿意。 -
Hong kong cinema has always been as integral part of chinese cinema, but, because of political and ideological reasons, chinese film historians had often neglected hong kong. such indifference enjoyed a reversal in recent years, when a new interest in hong kong films was found, with quite a number of books published on various aspects. conversely, hong kong film critics had also been resistant to establishing ties to the grand historical traditions of china, working hard to formulate an independent local indigenous perspective
香港電影本來就應該是中國電影的一個重要組成部份，只是由於政治環境和意識形態的分歧，中國電影史學者從來不把香港電影放在眼裡，直到近年，內地才興起一股香港電影熱潮，坊間亦出版了不少論述香港電影的書籍反過來說，香港電影評論界也往往抗拒與中國歷史的大傳統扯上關系，努力建構一種獨立的地方觀點，香港國際電影節歷年來的香港電影回顧部份倒在這方面做了不少工作，如早年的戰后香港電影回顧1946 - 1968 1979戰后國粵語片比較研究朱石麟秦劍等作品回顧1983香港電影的中國脈絡1990香港上海：電影雙城1994等。 -
