crystal perfection meaning in Chinese

晶体完整性

So in one hand it requires the wafer ' s diameter to be more large in order to enhance the productivity , and on the other hand it puts forward more strict requirement about the crystal perfection and electricity character . especially the electronic character and the equality of micro - area in the crystal wafer has become the key factor to determine whether the device can be made on it or not . so the resistivity measurement of micro - area become one most important procedure in the chip machining . to ensure the produce quality of chip and the perfect performance of final production , the four - probe testing technology need to be deeply studied
图形日益微细化，电路尺寸不断缩小，目前ic制造以8英寸、 0 . 13 m为主，预计在2007年左右将以12英寸、 65nm为主，这一方面要求圆片直径不断增大以提高生产率，另一方面对晶体的完美性、机械及电特性也提出了更为严格的要求。特别是微区的电学特性及其均匀性已经成为决定将来器件性能优劣的关键因素。因此，微区电阻率的测试成为芯片加工之中的重要工序。
