ComBond
The EVG® ComBond high-vacuum wafer bonding platform sets a new standard in EVG’s portfolio, designed to meet the growing demand for advanced integration processes. Ideal for a wide range of applications, including engineered substrates, stacked solar cells, power devices, high-end MEMS packaging, and beyond CMOS technologies, the EVG® ComBond addresses the most sophisticated bonding needs. Its modular cluster design offers exceptional flexibility, enabling customization for both R&D and high-throughput, high-volume manufacturing environments. The platform excels in bonding heterogeneous materials with different lattice constants and coefficients of thermal expansion (CTE), while its unique oxide-removal process enables the formation of electrically conductive bond interfaces. The high-vacuum technology of the EVG® ComBond also supports low-temperature bonding of metals, such as aluminum, which re-oxidize quickly in ambient environments. Void-free and particle free bond interfaces, along with exceptional bond strength, can be achieved for a broad range of material combinations, making it an ideal solution for advanced device fabrication.
