这里介绍的磨角法具有操作容易实用方便和不易碎片等优点.尤其是用来在薄的芯片上作特定部位的磨角显示更为方便.我们在对集成电路的芯片作纵向参数的解剖与分折时,曾用此法方便地在不到4mm~2厚度为200～300μ的芯片上选了7、8个特定部位作磨角显示,效果良好.下面对这一方法和原理作简单介绍.1.方法与步骤:①将2mm厚的制版玻璃边角料,划成30×100mm的方块和30×7mm的窄条.②用蜡将玻璃窄条粘在长方形玻璃板上,如图a所示.样品的结较深时可粘在位置
Mow angle method described here has the advantages of easy and convenient operation and non-fragile and so on.Especially for the thin part of the chip for the angle of the display is more convenient.We are in the integrated circuit chip longitudinal parameters of anatomy and Fracture, this method has been used in less than 4mm ~ 2 thickness of 200 ~ 300μ chip selected 7,8 specific parts for the angle display, the effect is good. The following method and principle for simple Introduction 1. Methods and Procedures ① Divide 2mm thick plate-making glass scrap into strips of 30 × 100mm and narrow strips of 30 × 7mm ② Use wax to stick the narrow strip of glass on the rectangular glass plate, Show samples can be more sticky in the knot position
