TSMC 行为面试题

Primly 研究团队为 TSMC 调研整理的面试题、流程细节和难度信号。

3 经验 难度 3.3/5 Semiconductors

Supply Chain Planning Manager

virtual · 难度 3/5

流程通常从 recruiter 和 hiring manager 的初筛开始,重点在规划范围、干系人管理,以及在复杂、产能受限环境中的运作经验。候选人反馈会有 panel 式面试,考察情景规划、在冲突需求下的优先级判断,以及与制造和采购伙伴的沟通。有些面试轮次会包含 case 讨论或简短展示,要求候选人说明将如何管理供需缺口、加急约束和供应商风险。整体周期通常是几周;如果岗位支持关键 fab ramp 或跨站点规划职能,可能会有额外轮次。

  • Describe how you would respond if forecasted demand exceeds available fab capacity for multiple high-priority customers.(如果预测需求超过 fab 可用产能,且涉及多个高优先级客户,你会如何应对?)
  • What KPIs would you use to manage shortages and expedite decisions, and how would you prevent firefighting from becoming the norm?(你会用哪些 KPI 来管理短缺和加急决策?你会如何避免救火变成常态?)
  • Tell me about a time you influenced manufacturing or engineering stakeholders without direct authority to change a plan.(讲讲一次你在没有直接权限改计划的情况下,影响了 manufacturing 或 engineering 干系人的经历。)
  • How do you balance customer commitments with internal realities in a culture that values execution and accountability?(在一个重视执行力和问责的文化里,你如何平衡对客户的承诺与内部现实?)

Equipment Engineer (Lithography)

virtual · 难度 3/5

流程通常从 recruiter screen 开始,确认专业方向、是否愿意倒班,以及对某个具体模块(如 lithography、etch 或 deposition)的兴趣。候选人反馈会有一场技术面试,重点考察排障思路、基础物理与仪器知识,以及维护或实验室设备的动手经验。后续阶段通常包括与 senior 工程师和一位 manager 的 1 到 3 轮面试,强调安全、流程纪律,以及候选人如何给设备 uptime 排优先级。一般几周内会出 offer,有时会取决于现场需求和班次分配。

  • How would you troubleshoot a tool that intermittently fails a wafer alignment step, and what logs or sensors would you check?(你会如何排查一台设备在 wafer alignment 步骤上间歇性失败?你会看哪些日志或传感器?)
  • Explain what you would look for to distinguish a particle issue from a focus or dose issue in lithography.(解释在 lithography 里,你会看哪些信号来区分 particle 问题和 focus 或 dose 问题。)
  • Tell me about a time you followed a strict procedure under time pressure without cutting corners.(讲讲一次你在时间压力下依然严格按流程执行、没有走捷径的经历。)
  • How do you handle handoffs between shifts to ensure the next team can continue troubleshooting effectively?(你如何处理不同班次之间的交接,确保下一组能继续高效排障?)

Process Integration Engineer

onsite · 难度 4/5

流程通常从 recruiter 主动联系或申请审核开始,然后进行电话初筛,以确认背景、对齐预期和地点灵活性。候选人反馈会有一轮或多轮与工程师以及一位 hiring manager 的技术面试,重点在半导体基础、工艺取舍和结构化问题解决。现场或延长的远程面试通常包含多场 1:1,覆盖 integration、module 和 yield 等干系人,有时还会要求做一个关于过往项目的简短技术展示。整体周期通常是几周走完,视地点和岗位关键程度,可能还会增加背调和入职前要求等步骤。

  • Walk through how you would diagnose a sudden yield drop after a process change, and what data you would request first.(讲讲在工艺变更后 yield 突然下降时,你会如何诊断,首先会要哪些数据?)
  • Explain the tradeoffs between adjusting etch time versus power when trying to hit a critical dimension target.(解释在要达到关键尺寸目标时,调整 etch 时间和调整功率之间的取舍。)
  • Describe a time you had to align multiple module owners on a change that improved yield but increased cycle time.(描述一次你需要让多个 module owner 对齐:某项变更能提升 yield,但会增加 cycle time。)
  • If a high-priority customer lot is at risk, how would you communicate status and drive containment across shifts?(如果一个高优先级客户 lot 有风险,你会如何同步状态,并推动不同班次之间的遏制措施?)
