临时键合（Temporary Bonding）常用于薄晶圆、TSV、背面金属化、晶圆级封装等路线中的搬运与背面加工；它不是只选一种胶或一片载片。器件片状态、载片材料、键合层、热预算、化学品、减薄载荷、翘曲、解键合方式和残胶控制彼此耦合，应在启动前一起核对。Temporary bonding supports thin wafers, TSV, backside metallization and wafer-level packaging routes. It is not just choosing an adhesive or carrier: device state, carrier, bond layer, thermal budget, chemicals, thinning load, bow, release method and residue control must be reviewed together.
需要对器件片做背磨、CMP、背面刻蚀、背面金属化或通孔后处理的项目；也适合薄片搬运、面板/晶圆级封装和需在后段安全释放的验证工作。Projects requiring backgrind, CMP, backside etch, backside metallization or via follow-on steps; also thin-wafer handling, panel/wafer-level packaging and validation work requiring a controlled release.
请提供器件片与载片的材料、尺寸、初始/目标厚度、正面凸起与保护要求；键合面状态、允许温度和溶剂/等离子/湿法条件；计划的减薄、清洗、沉积或刻蚀步骤；以及最终解键合后可接受的残胶、翘曲、颗粒和电学/外观验收方式。Provide device and carrier materials, format, initial/target thickness, front-side topography and protection; bond-surface state, allowed temperature and solvent/plasma/wet exposure; planned thinning, cleaning, deposition or etch; and acceptable post-release residue, bow, particle and electrical/visual checks.
键合空洞、边缘渗入、热失配或翘曲会让背面工序失稳；减薄压力、真空吸附和化学品可能改变键合层；解键合温度、机械力或光/化学释放也可能伤及器件。残胶、颗粒、裂片与后续金属或键合界面兼容性需提前定义。Voids, edge ingress, thermal mismatch and bow can destabilize backside work. Thinning load, vacuum handling and chemicals can change the bond layer; thermal, mechanical, photo or chemical release can also damage devices. Residue, particles, fracture and downstream metallization or bonding compatibility need defined limits.

建议把每一步的最高温度、接触介质、真空/压力、搬运方式和是否需要中间检测列成表。若涉及 TSV、超薄片或封装，请同时提供目标厚度、背面图形和后续互连计划。素微会先协助区分载片准备、临时键合、背面处理、清洗、解键合与残胶复核，避免只按“薄片加工”询价而遗漏释放风险。List the peak temperature, contact media, vacuum/pressure, handling and any in-process check for every step. For TSV, ultra-thin wafers or packaging, include target thickness, backside layout and downstream interconnect plan. We separate carrier preparation, temporary bonding, backside work, cleaning, release and residue review before matching resources.
提交临时键合与解键合需求Submit temporary bonding request若背面目标是减薄或抛光，应把目标厚度、TTV、翘曲和支撑方式一起确认。For thinning or CMP, confirm thickness, TTV, bow and support together.
查看晶圆减薄与 CMP 准备Open thinning and CMP guide涉及通孔和背面互连时，临时键合需与通孔、绝缘、金属化和减薄顺序一起核对。For vias and backside interconnect, align temporary bonding with via, dielectric, metallization and thinning sequence.
查看 TSV 硅通孔工艺需求Open TSV guide若临时键合是封装流程的一段，应与 I/O、热机械边界和测试交付一起确认。If temporary bonding is one packaging stage, align it with I/O, thermo-mechanical limits and test delivery.
