Glass and ceramics also have high volume resistivity, but poor surface properties at high humidity and often-poor piezoelectric properties.
玻璃和陶瓷也具有很高的体电阻率，但是在高湿度下表面电阻率性质较差，并且其压电性常常也较差。
A wafer with poor surface quality has hidden risks of stress concentration and little cracks, which would cause a huge damage of bursting crack when dicing the wafer.
表面质量不好的晶圆会存在应力集中、裂缝等隐患，在分割晶圆片时，会导致晶圆崩裂的巨大损失。
