Proceedings of the IEEE 2003 International Interconnect Technology Conference (Cat. No.03TH8695), 2003
Three-dimensional (3-D) integrated circuits can be fabricated by bonding previously-processed device layers using metal-metal bonds that also serve as layer-to-layer interconnects. Bonded copper interconnect test structures were created by thermocompression bonding, and the bond toughness was measured using a four-point bend test. The effects of bonding temperature, chamber ambient and copper thickness on bond quality were evaluated to optimize the ...

Three-dimensional (3-D) integrated circuits can be fabricated by bonding previously-processed device layers using metal-metal bonds that also serve as layer-to-layer interconnects. Bonded copper interconnect test structures were created by thermocompression bonding, and the bond toughness was measured using a four-point bend test. The effects of bonding temperature, chamber ambient and copper thickness on bond quality were evaluated to optimize the bonding process. A new copper surface cleaning method using glacial acetic acid was employed to obtain high toughness bonds(/spl sim/17 J/m/sup 2/) at low bonding temperatures (<300/spl deg/C).
We present a three dimensional (3D) microfluidic device fabricated by multiple-stacking of electroplated Ni patterns using surface-activated bonding (SAB) at room temperature. We successfully fabricated a micro heat exchanger as a feasibility device, which is 800 /spl mu/m square by stacking nine layers of 25 /spl mu/m-thick Ni patterns at alignment accuracy less than 1/spl mu/m. 3D fluidic channels which consist of vertical holes of 100 /spl mu/m diameter and horizontal paths 70 /spl mu/m wide and 100 /spl mu/m pitch were formed by simply stacking patterned Ni plates without any sacrificial layers.
The simultaneous formation of Cu/Sn microconnects and an adhesive bond during wafer level thermal compression bonding was evaluated using a 3D enabled single metal level test die and wafer. The wafer level bond process relied on locally dispensed adhesive to fix the dice to the wafer prior to bonding and to become a permanent bond during the bonding process. The die-to-wafer microconnect resistance was measured for micropad pitches of 59, 64, and 69 μm. The robustness of the Cu/Sn and adhesive bond was demonstrated by thinning the bonded die to 50 BC;m. Package level reliability testing of parts that were wire bonded into a thermally enhanced plastic ball grid array (PBGA) package indicates good reliability behavior and the absence of any intrinsic reliability-related issues in the microconnects.
A new approach to photo detection using pixel Hybrid Photon Detectors (pixel- HPD's) has been adopted for the LHCb-RICH detector. These devices use a hybrid pixel detector inside an evacuated photo tube providing high-precision, low noise detection of Cherenkov radiation. The approach takes advantage of modern CMOS technology offering many advantages over more traditional techniques. These advantages include extremely high sensitivity, low noise and fast readout. A major technological challenge was the encapsulation of a hybrid pixel detector inside a photo detector tube. The fabrication of the HPD tube involves packaging of the pixel detector assembly onto a ceramic carrier to form the photo-anode and the subsequent bake out of the pixel anode under vacuum. Both processes involve high temperatures. A fine pitch solder bump- bonding technique, which is compatible with the manufacture of hybrid photo detectors, has been developed. The technology and the tests used for qualifying the new process for pixel-HPD production are described. More than 40 pixel detector assemblies have been produced with almost all showing <1% of missing pixels. A number of assemblies were baked out using temperature cycles identical to those used for pixel-HPD manufacture. None of the assemblies demonstrated any degradation. SEM photos clearly indicate the reliability of the process. 10 pixel-HPD tubes have been produced using this new bump-bonding process and those behave according to expectations. The pixel-HPD is the first of a new generation of photo detector tubes suitable for RICH and other visible photon sensing applications
Wafer bonding provides a high degree of flexibility in material integration. However, the major concerns of Si wafer bonding with dissimilar materials are their thermal mismatch and the bubble generation during the annealing process. The former requires the annealing temperature as low as possible to achieve a sufficiently high bond energy. The latter depends on the removal of hydrocarbon contaminants from the mating surfaces prior to bonding. We have employed the described low temperature bonding approach in realizing bulk quality ultrathin SOI by an ion-implanted carbon etch stop, single crystal ultrathin Si on quartz or on glass and Si/ZnS.
An Au-Si eutectic wafer-level bonding process was developed for low- temperature vacuum packaging of MEMS devices. Using Au-Si eutectic bonding, devices were encapsulated by bonding a silicon cap wafer to a device wafer. Micromachined Pirani vacuum sensors were encapsulated in order to characterize the packaged pressures. These packages had cavity dimensions of 2.3times2.3 mm with a depth of 90 mum. Yields of 84.6% and 94.1% were achieved in packages with bond ring widths of 100 and 150 mum. With the use of getters and a pre- bond outgassing step, pressures from <3.7 to 23.3 mTorr were achieved. Furthermore, pressures were shown to remain stable to within plusmn2.5 mTorr for over 4 years of testing.
An algorithm that has been developed to inspect the integrity of wire bonds on an IC die is described. The algorithm uses of an elliptical model to approximate the shape of the bond so that any aberrations from the specified dimensions can be easily identified. Missing bonds and double bonds can also be detected.<<ETX>>
The performance of a piezoresistive transducer pressure sensor to thermal and pressure environments can be predicted by the finite element method. A simplified 1/8 model, considering silicon dioxide and nitride processes as well as stack-anodic bonding and adhesive bonding processes, was developed. The FEM results were found to be comparable to experimental data. Case studies suggested that a Pyrex stack induces a certain amount of non-linearity, while it isolates the hard epoxy nonlinear effect. Flexible epoxy bonding or soft adhesive bonding is preferred for the packaging process. The viscoelasticity and viscoplasticity of the bonding material will result in hysteresis and drift errors of the sensor output. However, the soft adhesive's influence on the sensor can be ignored under relatively stable environments. Moreover, detailed design and process information will help to improve the modeling application.
This paper reports on the design, fabrication and performance of a ferromagnetic shape memory alloy (FSMA) thin film actuator for two degrees of freedom (2D) control of a bulk micromirror. The actuation mechanism is based on a simultaneous ferromagnetic and martensitic transformation. A monolithic actuator design has been developed with two thermally and magnetically decoupled actuation units. The problem of FSMA thin film integration is solved by a novel transfer bonding process. First demonstrators of the FSMA actuator show a highly nonlinear response at low actuation voltage allowing large optical scanning angles up to 65 ° at tunable frequencies.
