Firstly surface region with bad quality is extracted and vertices of the surface region are approximated with b - spline surface . then the b - spline 首先将品质较差的曲面局部区域分离,然后拟合局部区域中的型值点建立可视模型。
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。
