《GB/T 29505-2013硅片平坦表面的表面粗糙度测量方法》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。
Scope
This standard provides the measurement principle, measurement equipment and procedures of the three methods commonly used in the measurement of the surface roughness of silicon wafers: profilometer, interferometer and scatterometer, and specifies the standard scanning position pattern and roughness of the local or entire area of the silicon wafer surface. Abbreviation definition. This standard applies to the roughness measurement of the surface of the flat silicon wafer; it can also be used for other types of flat wafer materials, but it is not applicable to the roughness measurement of the wafer edge area. This standard does not apply to measuring instruments with bandwidth spatial wavelength ≤ 10 nm.
