《GB/T 6620-1995硅片翘曲度非接触式测试方法》由TC203(全国半导体设备和材料标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准规定了硅单晶切割片、研磨片、抛光片翘曲度的非接触式测量方法。本标准适用于测量直径大于50mm,厚度为150~1000μm的圆形硅片的翘曲度。本标准也适用于测量其他半导体圆片的翘曲度。
Scope
This standard specifies the non-contact measurement method for the warpage of silicon single crystal cutting wafers, grinding wafers and polishing wafers (hereinafter referred to as silicon wafers). This standard is suitable for measuring the warpage of circular silicon wafers with a diameter greater than 50mm and a thickness of 150-1000μm. This standard is also suitable for measuring the warpage of other semiconductor wafers.
