Wafer rotation grinding, as an important processing technology, is widely used in manufacturing and back thinning of the silicon wafer. However, the surface/subsurface integrity of the ground wafer, which has important influences on the surface quality and the output of the wafer in subsequent process, is becoming an attention-catching problem.Micromachining of brittle materials like monocrystalline silicon to obtain deterministic surface topography is a 21st Century challenge. As the scale of machining has shrunk down to sub-micrometre dimensions, the undulations in the machined topography start to overlap with the extent of elastic recovery (spring back) of the workpiece, posing ...

Silicon wafers are used for production of most microchips. Various processes are needed to transfer a silicon crystal ingot into wafers. To ensure high surface quality, the damage layer generated by each of the machining processes (such as lapping and grinding) has to be removed by its subsequent processes. Therefore it is essential to assess the subsurface damage for each machining process.Accepted in Precision Engineering on 10/5/2020 1 1 Elastic recovery of monocrystalline silicon during ultra-fine 2 rotational grinding 3 Ning Huang1, Ying Yan1, Ping Zhou1*, Renke Kang1, Dongming Guo1 and 4 Saurav Goel2,3 5 1Key Laboratory for Precision and Non-traditional Machining Technology of Ministry of Education, 6 Dalian University of Technology, Dalian 116024, China
