輕摻雜 的英文怎麼說
中文拼音 [qīngchānzá]
輕摻雜
英文
lightly doped-
Then, the effect of heavily doped boron on ig of czochralski silicon was also investigated. it is found that no dz ( denuded zones ) were observed in the hb samples subjected to high one - step temperature, ramping annealing respectively. for conventional high - low - high three - step ig annealing, the dz becomes narrower and bmd density is higher in hb samples than that in lb samples, as a result of hb enhancing oxygen precipitation
結果顯示,單步高溫熱處理時重摻硼樣品不能形成潔凈區;降溫退火中,降溫速度較為緩慢( 3 / min )時能生成一定量的氧沉澱,但沒有潔凈區形成;普通高?低?高三步熱處理過程中,形成明顯的潔凈區,但相對輕摻樣品而言,潔凈區較窄,氧沉澱密度明顯偏高,說明重摻硼樣品吸雜能力強。The result is showed that the value of square resistence is 30. 2 o in heavily doping area and 100. 2o in lightly doping area
實驗結果顯示,重摻雜區和輕摻雜區的平均方塊電阻分別為30 . 2和100 . 2 ,相差70 。The abrupt heterojunction diode is composed of a 1 m thick heavily doped n - type sic layer and a 0. 4 m thick lightly doped p - type sic1 - xgex layer with varied composition ratios
在這個異質結中, n型重摻雜3c - sic層的厚度為1 m , p型輕摻雜sicge層厚度為0 . 4 m ,二者之間形成突變異質結。As far as the new technology of selective diffusion, the method of printing is used and the phosphoric paste ( high concentration ) is printed at the electrode - site in silicon. afterwards, a thin layer of phosphoric source ( low concentration ) is sprayed on the surface of the non - electrode - site in silicon
在選擇性擴散新工藝中,我們採用絲網印刷電極的方法在矽片的電極位置印刷濃度較高的磷漿(摻磷sio _ 2乳膠) ,在非電極區噴塗一層濃度較低的磷源,擴散后形成重摻雜和輕摻雜。In the new structure, a n + buffer layer is introduced into the bulk silicon substrate with a triple - diffusion process. the new structure has two features : one is the feature of npt - igbt : the thin and lightly - doped p + layer and the high lifetimes of the carriers ; the other is the feature of pt - igbt : n7n + structure which can make the n " region very thin
新結構用三重擴散的方法在n ~ -單晶片上引入了n ~ +緩沖層,仍然保留了npt - igbt中薄而輕摻雜p層和高載流子壽命的本質優點,同時又具有pt - igbt中n ~ - ( n ~ + )雙層復合的薄耐壓層(即薄基區)的優點。Thus it is considered that the technique of dz formation by means of rtp may not be suitable for heavily boron - doping cz silicon. since the higher concentration vacancy could decrease the stress inducing by oxygen precipitates, the size of the oxygen precipitation with higher density was smaller in the hb si samples in comparison with the samples without rtp pre - annealing. moreover, as for the technique to generate dz by rtp in lightly boron - doping samples, it was found that the behavior of oxygen precipitation and dz was determined by the annealed temperature, followed annealing and ambient of rtf as well
結果顯示,對于普通輕摻矽片能形成明顯的很寬的潔凈區的rtp預處理工藝,應用於重摻硼樣品時沒有潔凈區形成,所以rtp預處理獲得潔凈區的工藝不適用於重摻硼矽片,硼的大量摻雜對氧沉澱促進效果大於高濃度的空位對氧沉澱的洲排浙江大學碩士學位論文李春龍:直拉重摻硼硅單晶中氧沉澱的研究促進效果;大量空位的引入,有利於釋放氧沉澱生長過程的內應力,適當增加重摻硼樣品氧沉澱密度,減少其尺寸,並伴有層錯生成。By using the techniques including the zinc coating of cold rolled steel plate and the surface spray, the fiber cable distribution plate adopts spraying material doped with fire retardant materials. it is characterized as light, flexible, firm and durable. it has reliable cable inlet, grounding and fixing and the splicing between theterminal end and pigtail. users can select unit or ring flange amount according to their practical needs
採用鍍鋅處理冷軋鋼板和表面噴塗的工藝,光纖分配盤採用摻雜阻烯材料的噴縮材質,輕便靈活,又結實耐用,具有光纜引入固定和保護功能光纜終端與尾纖熔接功能,用戶可根據實際需求選配單元數量或法蘭盤數量。Polyaniline ( pan ) have potential applications in technology : such as light - emitting diodes ( led ), sensors, rechargeable batteries, photovoltaic cell, electromagnetic interference shielding and metal anti - corrosion because of their variable structure, varied electronic properties through doping and lightweight
聚苯胺由於具有結構多樣化,通過摻雜電導率可調,重量輕等特點,在發光二極體、傳感器、太陽能電池、二次電池、電磁屏蔽、金屬的防腐等領域呈現廣泛的應用前景。And the dopping magneto - optical materials were constructed to better meet the demand for the properties of magneto - optical disk recording media materials, forming the series magneto - optical recording media materials and decreasing the making cost by the method of introducing the light and middling rare - earth into the tbfeco materials. the magneto - optical properties and compositions of the tb - fe - co series dopping magnetic - optical film materials were investigated. the results show that when small amount of adulteration element was introduced into the tb - fe - co, the magneto - optical properties of materials are increased. for example the kerr angle and the coercive force are both improved
