VertaBond™
High-Volume Automated Vacuum Anneal System for WtW Hybrid Bonding, Die-to-Panel (DtP) and Panel-to-Panel (PtP) Bonding
Datasheet and Specs

Automated Vacuum Annealing System

The YES VertaBond™ vacuum furnace provides complete, reliable wafer and panel bonding in less time with a reduced thermal budget. Superior bond strength as well as excellent particle performance come from the VertaBond’s precise temperature uniformity in a low vacuum environment, resulting in significant improvements in the properties of bonded interfaces. It also acts to eliminate voids, which can cause yield loss and performance degradation. Innovative manufacturers utilize VertaBond for demanding 3D stacking and heterogeneous integration applications in HBM (high bandwidth memory) and other critical areas.
Automated Vacuum Annealing System

High-Volume Production | Low-temp Bonding and High-temp Vacuum Anneal in One Automated System

The production-proven VertaBond vacuum anneal system offers unparalleled uniform temperature control via proprietary laminar gas flow technology. With VertaBond, both low-temp direct hybrid bonding and high-temp vacuum anneal can run in the same chamber.

The VertaBond system offers:
-Repeatable, controllable results in high volume manufacturing
-Complete bonding with excellent reliability
-Excellent particle performance​ (<20 adders @>0.1µm)

VertaBond has an EFEM integrated with two process modules that can accommodate 200 mm and 300 mm wafers, or panel sizes ranging from 400 mm to 550 mm. VertaBond wafer systems can process batch sizes of 50 wafers (one PM) or 100 wafers (two PMs). VertaBond panel systems can process batch sizes of 12 panels (one PM) or 24 panels (two PMs).
