Alignment and wafer bonding are core processes for wafer-level capping, wafer-level packaging, engineered substrate manufacturing, wafer-level 3D integration, and wafer thinning. These processes have driven the remarkable growth of MEMS devices, RF filters, and BSI (Back-Side Illuminated) CIS (CMOS Image Sensors). Additionally, they enable the fabrication of engineered substrates such as SOI (Silicon on Insulator). Mainstream bonding processes include: adhesive bonding, anodic bonding, direct/fusion bonding, glass frit bonding, solder bonding (including eutectic and transient liquid phase bonding), and metal diffusion/thermocompression bonding. The TORCH520 Bonder is primarily designed for 8-inch (D200mm) wafer bonding. It achieves wafer bonding through uniform pressure application and precise displacement control under thermal conditions. The equipment offers optional pressurization processes in low vacuum (0.1 mbar) or high vacuum (1E-6 mbar), with a maximum pressure of 60 KN and a maximum heating temperature of 650°C under pressurization. It can meet a temperature ramp-up/ramp-down rate requirement of 40K/min, and provides positive pressure atmosphere protection at the end of the process, with a protective pressure up to 3 bar. The system features an ergonomically designed top-opening upper and lower chamber structure, and is equipped with a closed-loop water chiller for rapid cooling via circulating water. An optional formic acid cleaning process is available prior to bonding. Specifications Number of chambers: 1 Temperature control: Independent temperature control for upper and lower pressure heads Chamber opening mode: Ergonomically designed top-opening chamber System cooling: Circulating water cooling with a closed-loop water cooling heat exchanger Optional configurations: Pressurization protection; formic acid atmosphere
