晶圆减薄与 CMP 抛光，先定义目标厚度、平整度和表面质量。Wafer thinning and CMP start with target thickness, flatness and surface quality.

背磨、精磨、机械抛光和 CMP 对应不同的去除量与表面目标。可行性还取决于材料、初始厚度、正面器件保护、边缘状态、临时键合方式以及减薄后的搬运和切割计划。Backgrinding, fine grinding, mechanical polishing and CMP serve different removal and surface targets, with feasibility shaped by material, front-side protection, edge state, temporary bonding and downstream handling.

01

适合什么需求Good For

硅片、玻璃或化合物半导体减薄，封装前背磨，光学或键合前抛光，以及需要控制 TTV、翘曲、粗糙度和亚表面损伤的样品。Silicon, glass or compound-semiconductor thinning, packaging backgrind, pre-bond polishing and controlled TTV, bow or roughness.

02

需要准备什么Prepare First

材料和片径、初始与目标厚度、厚度容差/TTV、目标粗糙度、正背面膜层、器件保护边界、数量及后续划片或键合要求。Material, diameter, initial and target thickness, tolerance/TTV, roughness, films, device protection, quantity and downstream dicing or bonding.

03

常见风险Common Risks

薄片破损、边缘崩缺、厚度不均和翘曲，磨削损伤或划痕，正面结构受压、保护胶残留，以及清洗和解键合造成污染。Thin-wafer breakage, edge chips, TTV, bow, grinding damage, scratches, front-side pressure, adhesive residue and debond contamination.

推荐下一步Next Step

先把厚度、TTV、粗糙度和后续工序写进同一张验收表。Put thickness, TTV, roughness and downstream steps into one acceptance sheet.

请提交晶圆材料与直径、初始/目标厚度、允许 TTV 和翘曲、表面粗糙度、正面结构照片及保护限制。微纳Hub 会先判断背磨、精磨、机械抛光或 CMP 的组合，并确认临时键合、清洗、测厚、包装与后续划片边界。Share material, diameter, initial/target thickness, TTV, bow, roughness, front-side images and protection limits so grinding, polishing and CMP can be combined appropriately.
