Ziptronix is the only company with the technology enabling room temperature, non-adhesive wafer-to-wafer and die-to-wafer bonding for a wide variety of semiconductor materials. The proprietary ZiBond process enables the bonding of multiple materials in previously impossible combinations by using a very thin layer of silicon oxide to facilitate direct bonding. Since the process is completed at room temperature, there are no residual stresses, (which can occur with thermal or anodic bonding methods.) The mechanical wafer preparation is based on a standard chemical-mechanical polish, which then enables many material combinations to be bonded directly. The spectrum of possibilities includes combinations from silicon-to-silicon, germanium, indium phosphide, gallium arsenide, gallium nitride, quartz, and others. The resulting bond strength typically exceeds the fracture strength of the bonded bulk materials. Ziptronix technology can immediately produce custom wafers and substrates tailored to specific thermal characteristics or other process requirements.
