BONDSCALE™ Automated Production Fusion Bonding System

Enabling 3D Integration for More Moore


EVG BONDSCALE is designed to fulfill a wide range of fusion wafer bonding applications, including engineered substrate manufacturing and 3D integration approaches that use layer-transfer processing, such as monolithic 3D (M3D). With BONDSCALE, EVG is bringing wafer bonding to front-end semiconductor processing and helping to address long-term challenges for “More Moore” logic device scaling identified in the International Roadmap for Devices and Systems (IRDS). Incorporating an enhanced edge alignment technology, BONDSCALE provides a significant boost in wafer bond productivity and
lower cost of ownership (CoO) compared to existing fusion bonding platforms.

BONDSCALE is being sold alongside EVG's industry benchmark GEMINI FB XT automated fusion bonding system, with each platform targeting different applications. While BONDSCALE will primarily focus on engineered substrate bonding and layer-transfer processing, the GEMINI FB XT will support applications requiring higher alignment accuracies, such as memory stacking, 3D systems on chip (SoC), backside illuminated CMOS image sensor stacking, and die partitioning.

Features & Applications 

  • Fully-automated fusion bonding of 200 and 300 mm wafers in a single platform with cleaning, plasma activation, alignment, pre-bonding, and IR inspection possible
  • Direct wafer bonding with plasma activation for heterogeneous integration of different materials, high-quality engineered substrates as well as thin-silicon layer transfer applications
  • Layer transfer processes and engineered substrates enabling logic scaling, 3D integration such as M3, 3D VLSI including backside power distribution, N&P stacking, logic-on-memory, clustered functional stacks and beyond-CMOS adoption
