EV Group

Known for its automation flexibility and reliability, the EVG6200 NT provides state-of-the-art mask alignment technology on a minimized footprint area combined with the utmost throughput, advanced alignment features and optimized total cost of ownership. Operator-friendly software, minimized time for mask and tooling changes, as well as efficient worldwide service and support makes it the ideal solution for any manufacturing environment. The EVG6200 NT or the fully-housed EVG6200 NT Gen2 mask alignment systems are available in semi-automated or automated configuration and equipped with integrated vibration isolation to achieve excellent exposure results for a wide range of applications, such as exposure of thin and thick resists, patterning of deep cavities and comparable topographies, as well as processing of thin and fragile materials such as compound semiconductors. Furthermore, the EVG’s proprietary SmartNIL technology is supported on both semi-automated and fully automated system configurations.

Vertical stacking of semiconductor devices has become an increasingly viable approach to enabling continuous improvements in device density and performance. Wafer-to-wafer bonding is an essential process step to enable 3D stacked devices. EVG's GEMINI FB XT integrated fusion bonding system extends current standards and combines higher productivity with improved alignment and overlay accuracy for applications such as memory stacking, 3D systems on chip (SoC), backside illuminated CMOS image sensor stacking, and die partitioning. The system features the SmartView bond aligner, developed specifically for fusion and hybrid wafer bonding alignment requirements.

The fully automated temporary bonding system achieves the whole temporary bonding process – starting with temporary adhesive application, baking, alignment and bonding of the device wafer to the carrier wafer – within one automated tool. The equipment layout is modular as with all EVG’s fully automated tools, meaning it can be throughput-optimized depending on the specific process.

Because of EVG’s open platform, different types of temporary bonding adhesives can be used, such as spin coat thermoplast, thermoset materials, or tapes.

The EVG®850 DB is a fully automated debonder for the separation and cleaning of processed temporary bonding wafer stacks. The fragile device wafers are always supported either through film frame mounting or through a thin wafer handler.

The EVG610 supports a variety of standard lithography processes, such as vacuum-, hard-, soft-, and proximity exposure modes, with the option of back-side alignment. Moreover the system offers additional capabilities including bond alignment and nanoimprint lithography (NIL). The EVG610 offers quick processing and re-tooling for changing user requirements with a conversion time of less than a few minutes. Its advanced multi-user concept can be adapted from beginners to expert level, thus making it ideal for universities and R&D applications.
