1 Materials Characterization for Stress Management Ehrenfried Zschech, Fraunhofer IZFP Dresden, Germany Workshop on Stress Management for 3D ICs using TSVs San Francisco/CA, July 13, 2010

2 Outline Stress management in complex systems: The need of multi-scale materials characterization Materials parameters database Device strain measurements for model validation / calibration Interaction modeling / simulation multi-scale materials data

3 Outline Stress management in complex systems: The need of multi-scale materials characterization Materials parameters database Device strain measurements for model validation / calibration Interaction modeling / simulation multi-scale materials data

4 Materials data, techniques and validation Questions to be answered: - Which DATA is needed, what needs to be measured? - Which CHARACTERIZATION TECHNIQUES are needed? - Which VALIDATION is needed?

5 Stress engineering for 3D TSV-based technology * Chip Performance o FET stress engineering vs. 3D IC integration impact (wafer thinning to some 10 µm, metal TSV, metal micro-bumps, ) o Effect of package-induced stress on transistor-to-transistor performance variation through variation in carrier mobility and threshold voltage (effect on device characteristics) o Stress effect on leakage and power Reliability o 3D thermal and stress effects in electromigration and stress migration o ILD/IMD cracking, delamination, etc. * Particular integration scheme: via-middle (particularly sensitive to mechanical stress) 5

7 Multi-scale materials characterization - Stress management in complex systems (packaged dies, 3D integration, etc.) requires multi-scale modeling and MULTI-SCALE CHARACTERIZATION. - Local materials modifications require MULTI-SCALE CHARACTERIZATION. Example: Low-k/ultra low-k dielectrics 1) E in IMD in dense OSG 2) E in UV-cured porous OSG - Analytical TECHNIQUES with different spatial resolution are needed.

8 Multi-scale materials mechanical characterization Scale 10 mm 1 mm 1 µm 1 nm Macro Micro Nano Tensile tester Micro-shear tester Nanoindenter Bending tester DMA AFAM 4P bending Ultrasonic microscopy F specimen E(T,t), CTE(T), Poisson(T), (visco)-plasticity, viscoelasticity geometry and microstructure dependency

9 Outline Stress management in complex systems: The need of multi-scale materials characterization Materials parameters database Device strain measurements for model validation / calibration Interaction modeling / simulation multi-scale materials data

10 Materials parameters database Materials parameters database is needed o as input for modeling / simulation o For each technology node (characterized by geometry, materials, strain, ) Multi-scale materials parameters are needed o for wafer-level materials o for packaging materials 10

11 Materials for assembly and packaging Materials Functionality Chemical Compositions Materials properties Measurement techniques Interposer (organic PCB) Chip carrier and electr. redistribution Composit of epoxy polymer and glass fibers E=f(T,t) CTE=f(T) Poisson=f(T) DMA, bending test TMA, image correlation Molding compound Chip encapsulation, protector Ceramics-filled epoxy polymer E=f(T,t), K=(T,t) CTE=f(T) Poisson=f(T) microstructure DMA, tensile tests, compression test TMA, image correlation ultra sonic transmission microscopy E=f(T) Nanoindentation Solder balls Electrical and mechanical connection Sn-rich alloy (SnAg3.5, SnAgCuA y B z ) visco-plasticity CTE=f(T) Poisson=f(T) micro shear tester, tensile tester, image correlation ultra sonic transmission microscopy microstructure FIB-SEM, EBSD Cu pillars Electrical and mechanical connection Electroplated Cu E=f(T), Plasticity CTE=f(T) Poisson=f(T) microstructure nanoindentation, tensile tests Image correlation ultra sonic transmission microscopy FIB/SEM, EBSD Underfiller Mechanical stabilization of joints Epoxy resin (filled & unfilled) E=f(T,t), K=(T,t) CTE=f(T) DMA, tensile tests, compression test TMA, image correlation

12 Materials for wafer-level process Materials Functionality Chemical Compositions Materials properties Measurement techniques Tungsten, Copper ILD: SiO 2, low-k, ULK Electrical wiring Insulation W, Cu, Cu alloy SiO 2 -based, FSG, low-k, ULK (SiCOH) E, v CTE strain grain size, texture E, v CTE adhesion Silicide Contact NiSi x, NiSi x A y E, v Stress liner Stress in channel SiN x CTE E, v CTE strain Nanoindentation, AFAM X-ray reflectometry X-Ray diffraction Blanket films: XRD, Patterned structures: OIM (SEM, TEM) Nanoindentation, scratch test AFAM/FM-AFM, UFM X-ray reflectometry 4-point bending, DCB Ellipsometry, TEM-EELS Nanoindentation, AFAM/FM-AFM X-ray reflectometry Ultra sonic transmission microscopy Nanoindentation X-ray reflectometry Blanket films: Wafer curvature Passivation Adhesion, etch stop, barrier SiN x C y, SiN x E, v CTE Nanoindentation X-ray reflectometry Si channel FET channel Si (in future Ge, III-V?) strain TEM (NBED, DFEH), NanoRaman

13 Outline Stress management in complex systems: The need of multi-scale materials characterization Materials parameters database Device strain measurements for model validation / calibration Interaction modeling / simulation multi-scale materials data

14 Validation/Calibration Electrical measurements: I on, V t, etc. o Fast & accurate measurements o Specially designed test-chip is needed expensive & time consuming o Stress variation is not responsible for total variation in electrical characteristics. Other sources of variability should be accounted: - sub-wavelength lithography - random dopant fluctuation - temperature fluctuation, etc. Strain measurements inside transistor channel o Direct but time consuming measurements o No need in test chip 14

16 Strain analysis in Silicon Wafer curvature: Stress = Force / Area (Stoney equation) X-ray diffraction: Strain via lattice parameter changes (Bragg equation) TEM analysis: Photoluminescence: Strain via lattice parameter changes (HRTEM, CBED, NBED, HoloDark) Strain via band gap changes Raman spectroscopy: Strain via lattice vibrations

17 High-Resolution TEM (HR-TEM) SSOI Difficulties: Thin-film relaxation Insufficient precession due to missing unstrained reference

25 Comparison of various strain analysis techniques TEM Method Advantages Disadvantages CBED NBED High accuracy Suitable for Si bulk & SOI substrates Applicable for thick lamellae (no stress relaxation) Strong influence of sample bending Strain mapping time consuming Modeling to assess strain relaxation Spatial resolution (improvement with probe Cs-corrector possible) HRTEM DFEH (HoloDark) High spatial resolution Continuous strain mapping High accuracy Large field of view Continuous strain mapping Stress relaxation due to thin specimens Limited application for SOI substrates Limited field of view Modeling to assess strain relaxation Limited application for SOI substrates Highly advanced TEM setup (Holography + image Cs-corrector)

26 Model calibration / validation Status for high-resolution techniques to determine strain in devices o Only TEM techniques are able to characterize strain in silicon channels of devices (~ 10 nm dimension) o Nano Beam Electron Diffraction (NBED) o HoloDark (DFEH) technique (not for SOI!) o NanoRaman spectroscopy is currently limited to nm spatial resolution 26
