denuded zone造句

• 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
  结果显示，单步高温热处理时重掺硼样品不能形成洁净区；降温退火中，降温速度较为缓慢( 3 / min )时能生成一定量的氧沉淀，但没有洁净区形成；普通高?低?高三步热处理过程中，形成明显的洁净区，但相对轻掺样品而言，洁净区较窄，氧沉淀密度明显偏高，说明重掺硼样品吸杂能力强。
• With the development of vlsi ( very large scale integration ) and ulsi ( ultra large scale integration ) , rtp ( rapid thermal process ) , which consumes less time and less energy than classical thermal treatments , have been widely employed in semiconductor manufacturing . however , the most importance is that rtp is applied for defects engineering of silicon material . it is generally believed the rtf leads to the injection of additional vacancies into silicon wafer , and then a so - called magic denuded zone ( mdz ) in the near - surface region of cz silicon wafer was formed by controlling the vacancy distribution
  随着大规模集成电路( vlsi )和超大规模集成电路的发展，节省时间、节省能量、容易控制的快速热退火工艺在半导体器件制造工艺中得到了广泛的应用，并且在硅材料的缺陷工程中发挥了特殊的作用，人们通过高温快速热处理在硅片中引入空位，并控制空位的分布，进而形成了具有较强内吸杂能力的洁净区。
