measuring grid-
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
圖形日益微細化，電路尺寸不斷縮小，目前ic製造以8英寸、 0 . 13 m為主，預計在2007年左右將以12英寸、 65nm為主，這一方面要求圓片直徑不斷增大以提高生產率，另一方面對晶體的完美性、機械及電特性也提出了更為嚴格的要求。特別是微區的電學特性及其均勻性已經成為決定將來器件性能優劣的關鍵因素。因此，微區電阻率的測試成為晶元加工之中的重要工序。Since its inception in 1985, has produced car audio and navigation equipment over 4000 thousand sets. with 12570m2 workshop equipted 4 smt equipments, its production capability is 600, 000 sets annual. our r d center and car audio testing centre can meet the needs of your new feature and style sooner
