阳极键合,先确认玻璃体系、表面状态与腔体气密目标。Anodic bonding starts with glass chemistry, surface condition and cavity-hermeticity targets.

阳极键合利用温度与电场实现硅和含碱玻璃的永久连接,常用于 MEMS 腔体、压力传感器与微流控封装。路线判断要同时核对玻璃热膨胀系数、界面洁净度、图形台阶、对准精度和器件耐压耐温边界。Anodic bonding permanently joins silicon and alkali-containing glass for MEMS cavities, sensors and microfluidics; feasibility depends on material, surface, topology, alignment and device limits.

01

适合什么需求Good For

硅-玻璃 MEMS 腔体封装、压力或惯性传感器、可视化微流道、真空或受控气氛腔体,以及需要晶圆级永久键合的器件。Silicon-glass MEMS cavities, pressure or inertial sensors, visible microchannels and wafer-level permanent packages.

02

需要准备什么Prepare First

硅片与玻璃牌号、片径和厚度、表面粗糙度与翘曲、腔体深度、金属或介质层、对准 mark、目标温度电压及键合气氛。Silicon and glass grades, wafer format, roughness, bow, cavity depth, films, alignment marks, temperature, voltage and atmosphere.

03

常见风险Common Risks

颗粒导致未键合区、台阶或粗糙度过大、热膨胀失配引发裂片、金属离子迁移、腔体压强偏差、对准漂移和后续切割崩边。Particles, excessive topology, thermal mismatch, ion migration, cavity-pressure error, overlay drift and dicing damage.

推荐下一步Next Step

把“硅玻璃封装”转换成材料、界面、窗口和气密验收表。Translate silicon-glass packaging into material, interface, process-window and hermeticity inputs.

请提交材料牌号、片径厚度、结构截面、腔体与引线布局、表面状态、对准公差、温度电压上限,以及泄漏、剪切强度或红外空洞检查标准。微纳Hub 会先比较阳极键合、直接键合与中间层键合路线。Share materials, section, cavity and feedthrough layout, surface state, overlay tolerance, process limits and leak, strength or void-inspection criteria.
