The universal XBS200 platform allows for aligned wafer bonding of wafer sizes up to 200 mm. Its versatility and modular design offer maximum process flexibility in all permanent bonding tasks. A novel aligned wafer transfer method eliminates the complexity of traditional systems and offers consistent process results with excellent system availability. The XBS200 platform offers low cost of ownership for high-volume production of MEMS, LED and 3D devices.
Submicron alignment accuracy
High process repeatability
Low cost of ownership
The XBS200 handles single wafers as well as aligned- and bonded wafer pairs by making use of a novel aligned wafer transfer method. It offers wafer cassette stations with integrated mapping and a camera-based optical pre-aligner with optional ID readers. An optional camera system allows to monitor and record the inside of the machine. A cyclic scheduling algorithm with automated throughput optimization ensures consistent timing of all processes and continuous run capability.
The new XBA bond aligner delivers consistent submicron alignment accuracy for transparent or non-transparent wafers by using our proprietary inter-substrate-alignment (ISA) technology. Built-in fixed reference, global calibration and overlay verification ensure optimum repeatability. Global calibration wafers are an integral part of the system and make automated calibration and overlay verification simple and quick.
The XB200 bond chamber is the process module version of the stand-alone XB8 bonder. It offers a wide parameter window and is therefore ideal for any thermo-compression bonding processes. Bond force options include a 60 kN and a 100 kN version and a temperature range of up to 550 °C is available. Reproducible process results from wafer to wafer achieve a consistently high product quality.
