3 Quick Introduction to EV Group st Our philosophy Our mission in serving next generation application in semiconductor technology Equipment supplier for the semiconductor and MEMS industry equipment installations Privately held company founded in 1980 Headquartered in Austria - subsidiaries in USA, JP, KR, CN and TW Worldwide Sales and Customer Support Network Internal process development 20% of revenue is invested into R&D annually
4 MEMS, IoT & Wearables Sensor (R)evolution Novel Sensors: Development of new measurement units (IMU, environmental, health, ) Smart Software: Combo sensors as integration of multiple measurement units and data processing Size and Power Reduction: Steady volume reduction (footprint and thickness) as well as power reduction
5 Outline Introduction Vacuum Encapsulation Metal Bonding Overview Conclusion
6 Vacuum Sealing in MEMS Why? Vacuum encapsulation in MEMS is based on three primary drivers: 1. Reduce the power consumption caused by parasitic drag on a resonator: - Gyroscopes 2. Reduce convection heat transfer: - Microbolometers - Temperature-controlled devices 3. Prevent corrosion or other types of interaction with O 2 or H 2 O: - Parts with exposed Al or AlN Source: ST 6
7 Vacuum MEMS Cavity Pressure Different Applications demand different pressure levels MEMS Device Working Pressure Accelerometer mbar Absolute pressure sensor mbar Gyroscope mbar Rotation Acceleration Sensor mbar Resonant Magnetometer mbar Microbolometer < 10-4 mbar RF switch < 10-4 mbar Oscillators < 10-4 mbar Sources: A. Bonucci, A. Conte, M. Moraja, G. Longoni and M. Amiotti, Chapter 40: Outgassing and Gettering, in Handbook of Silicon-based MEMS: materials and technologies, pp. 585 V. Lindroos, M. Tilli, A. Lehto and T. Motooka (ed.), Elsevier, 2010 (ISBN: ) 7
8 Bonding Requirements for Vacuum Sealing CMOS compatibility Temperature limits of MEMS sensor and CMOS processing (Al-Ge or Al-Al) Contamination limitation Material compatibility Bonding Requirements
9 CMOS Compatibility Various CMOS-MEMS are using in production low temperature fusion bonding, eutectic, TLP bonding. Fusion bonding not compatible with high vacuum levels, even with getters. Only one eutectic system was proven to be compatible with CMOS: Al-Ge (volume production). Major disadvantage: process conditions too close to the limits of low temperature range (>400 C)! Al-Al thermo-compression bonding foreseen as a candidate. Major disadvantage: hard-to-handle, chemically-robust native oxide. 9
10 Bonding Requirements for Vacuum Sealing CMOS compatibility Temperature limits of MEMS sensor and CMOS processing (Al-Ge or Al-Al) Contamination limitation Material compatibility Bonding Requirements Stress management Bow and Warp management are gaining importance in vacuum sealing High temperature processing
11 Stress Management The use of MEMS specific patterning processes may result in high bow of incoming substrates, which subsequently can be responsible of inducing stress during bonding process. The specific MEMS requirements in terms of vacuum may impose substrates heating under vacuum for significant time, which may result in thermally-induced stress (high temperature difference between the two substrates) or extremely long process times. The use of high compression forces required by some bonding processes may induce stress in resonator structures. 11
12 Bonding Requirements for Vacuum Sealing CMOS compatibility Temperature limits of MEMS sensor and CMOS processing (Al-Ge or Al-Al) Contamination limitation Material compatibility Bonding Requirements Stress management Bow and Warp management are gaining importance in vacuum sealing High temperature processing Long term stability of vacuum inside devices Getters and high vacuum bake outs are competing New equipment concepts are underway for high vacuum sealing
13 Long Term Vacuum Stability The use of MEMS getters is becoming common in some vacuum MEMS. Disadvantages: hard to match thermally the various wafer bonding processes in use this results in decreasing the getter efficiency require additional patterning steps for getter deposition consume space inside device (High) vacuum baking prior bonding: a process which may avoid the use of getters but with most wafer bonder designs this results in unacceptable increase of process time. New equipment concepts address this issue. 13
14 Bonding Requirements for Vacuum Sealing CMOS compatibility Temperature limits of MEMS sensor and CMOS processing (Al-Ge or Al-Al) Contamination limitation Material compatibility Bonding Requirements Stress management Bow and Warp management are gaining importance in vacuum sealing High temperature processing Long term stability of vacuum inside devices Getters and high vacuum bake outs are competing New equipment concepts are underway for high vacuum sealing Direct vacuum measurement Testing schemes need to be optimized for high vacuum MEMS devices Testing integration into process flow Wafer level testing will be required

Residual gas analysis (RGA) Gas volume: >10-12 Pa l Destructive test, laborious for small packages 15

21 Eutectic Wafer Bonding Melting temperature Material A Temperature Time Material B Melting Point of the alloy is lower than of the individual materials Thickness of the material B and diffusion coefficient define process time
22 Eutectic Wafer Bonding: Step 1 Contacting Melting temperature Temperature x (µm) Time Wafers are aligned and brought into contact 1.00 c (a.u.) 0.00 Due to surface roughness no direct joint of the materials
