By adjusting the dose and energy of the additional boron implantation, the boron loss in the edge cell active area is compensated. As a result, the programming efficiency of edge cells has been remarkably improved. 通过调节硼注入的剂量和能量,边角单元有源区的硼浓度得到了补偿,边角单元获得了和中心单元几乎相同的编程效率。
With the aid of TCAD process simulation, it is believed that boron segregation which reduces the boron doping of edge cell active area is the main cause of lower programming efficiency of edge cells. 借助于TCAD工艺仿真,发现STI引起的硼析出效应降低了边角单元有源区的硼浓度,是边角单元编程效率降低的主要原因。
A method was brought forward to describe and analysis cell image, which is based on fitting the edge of cell image with straight line. Introduced and discussed the principle, implement method, the result of experiment and the disadvantage of this method. 提出了一种基于细胞图像边缘直线拟合的细胞图像描述和分析的方法,对这种方法的原理、实现方法、实验结果和存在不足进行介绍和分析。
After LPS stimulation, F-actin forms a denser skeleton layer at the edge of cell and an uneven distribution. 在LPS刺激后,F一actin在细胞边缘形成一宽厚的骨架层,同时发现该层分布不均匀,提示在一些部位可能会有伪足形成。
A pseudopod-like peripheral wing projecting from the peripheral edge of cell body with a smooth surface was observed forming ventral and dorsal marginal grooves respectively with the lateral crest, and the dorsal surface of cell body. 虫体周缘具有突出的伪足样周翼,其背腹面均光滑,该翼与腹吸盘侧嵴和虫体背面之间分别形成边缘沟。
