Example Sentences:

	1.	Study on the influence of grading and impurity distribution for the properties of phosphogysum 杂质分布对其性能影响的研究
	2.	The performance of devices is directly decided by the impurity distribution in the diffused region , and the impurity distribution may be affected by the material thermal properties , the mechanism of diffusion , the power of laser and the diffusion time 激光诱导扩散过程中,基片的热物理特性、扩散源的扩散机理、激光束的功率大小和扩散时间以及光束的聚焦状况等等,都会对扩散结果产生重要的影响,而扩散层的杂质分布情况将直接决定器件的性能指标。
	3.	At present , the problem in testing sheet resistance for micro - areas is that probes must be set up at the suitable locations by handwork . in order to know the wafer ' s impurity distributing , we need test many times , so will waste a lot of time . if the wafer ' s diameter would be 300mm , this problem will be more serious . in this paper , image analysis is introduced , through pre - processing and edge picking - up , the probe tips are recognized . then probe tips will be aligned respectively in two perpendicular directions through driving stepper motors . thus the distribution of sheet resistance for whole wafer is got by automatic testing and it offers information for detecting the impurity distribution and the diffusion uniformity 这样，完成200mm ( 8时)圆片杂质的扩散分布需要对许多图形进行测试，需要花费很长的时间，当测试300mm硅片时问题就更为突出。本文将图象与视觉测量系统引入四探针测试系统中，对采集到的原始探针图像进行预处理、边缘提取等操作，以便实现探针针尖的识别，然后由电机控制实现探针的自动定位。这样测试系统可以自动获得全片的薄层电阻分布，为超大规模集成电路检测杂质分布和扩散的均匀性提供信息。
