  • EVG®40 NT2 offers breakthrough metrology performance to accelerate implementation of
    wafer- and die-level hybrid bonding and maskless lithography

    ST. FLORIAN, Austria, November 15, 2021—EV Group (EVG), a leading supplier of wafer bonding and lithography equipment for the MEMS, nanotechnology and semiconductor markets, today unveiled the EVG®40 NT2 automated metrology system, which provides overlay and critical dimension (CD) measurements for wafer-to-wafer (W2W), die-to-wafer (D2W) and die-to-die (D2D) bonding as well as maskless lithography applications. Designed for high-volume production with feedback loops for real-time process correction and optimization, the EVG40 NT2 helps device manufacturers, foundries and packaging houses accelerate the introduction of new 3D/heterogeneous integration products as well as improve yields and avoid scrapping of highly valuable wafers.

    EVG will showcase the EVG40 NT2 system for the first time at the SEMICON Europa tradeshow, taking place November 16-19 at the Messe München in Munich, Germany. Attendees interested in learning more can visit EVG in Hall B1, booth B1460.

    Heterogeneous Integration Roadmap Driving New Metrology Needs

    As traditional 2D silicon scaling reaches its cost limits, the semiconductor industry is turning to heterogeneous integration—the manufacturing, assembly and packaging of multiple different components or dies with different feature sizes and materials onto a single device or package—in order to increase performance on new device generations. In W2W, D2W and D2D bonding, tight alignment and overlay accuracy is required to achieve good electrical contact between the interconnected devices. As interconnect pitches become tighter with each new product generation, wafer and die bond alignment and overlay processes must also scale accordingly, with greater accuracy and more frequent measurements to identify process problems when they occur in order to provide corrective action or the possibility for rework, leading to higher production yields. Maskless exposure, an innovative lithographic approach for 3D/heterogeneous integration, requires increasingly precise pattern fidelity and pattern overlay on highly warped and distorted wafers that often incorporate shifted dies—driving the need for metrology that delivers crucial information on die position.

    “Process control is increasingly critical for leading-edge 3D and heterogeneous integration applications,” stated Dr. Thomas Glinsner, corporate technology director at EV Group. “The EVG40 NT2 represents a major breakthrough in metrology performance to meet the new demands for the advanced packaging industry. It provides not only greater overlay accuracy but also a significant boost in throughput to enable higher measurement density per wafer, giving more detailed feedback on hybrid bonding performance, for example. This new metrology solution rounds out EVG’s comprehensive portfolio of process solutions for 3D/heterogeneous integration, and complements our existing EVG40 NT system, which remains the de facto bond metrology standard for MEMS and complex photonic devices. The EVG40 NT2 is already playing a key role in several joint development projects underway at EVG’s Heterogeneous Integration Competence Center™.”



    High-Precision, High-Throughput Metrology Performance

    The EVG40 NT2 system provides highly precise measurements of critical bonding and lithography process parameters for current and future leading-edge 3D/heterogeneous integration applications. These measurements include: alignment verification and monitoring for W2W, D2W, D2D and maskless exposure processes; CD measurement; and multi-layer thickness measurement. It is a highly scalable system that features multiple measurement heads and a high-precision stage designed for high-throughput and high-accuracy (down to the low single-digit nm range) bonding and maskless exposure alignment verification. For alignment verification, the EVG40 NT2 generates an overlay model that can be used in a feedback loop for improving overall alignment. This reduces systematic errors and results in increased production yields. The system is compatible with multiple line optimization concepts for overlay feedback and die position feed-forward required by next-generation fabs supporting Industry 4.0 manufacturing.

    Product Availability

    EVG is now accepting orders for the new EVG40 NT2 automated metrology system, and offering product demonstrations at EVG’s Heterogeneous Integration Competence Center at its headquarters in Austria. For more information, please visit https://www.evgroup.com/products/metrology/.

BEWARE - Special Warning Notice about ExpoGuide and FAIRGuide

With the ongoing solicitations, SEMI would like to continue to alert you with questionable professional practices perpetrated against exhibitors by FairGuide.com (Austria) and Expo Guide (Mexico), Event Fair - The Exhibitors' Guide with their misleading directory services. There may be others that we are not aware of and are hence not named here. 

These companies provide legitimate exhibition guides aimed at exhibitors across the globe offering online listing services. They use a form which resembles and organizer's free catalogue listing service, inviting exhibitors to complete the form for an entry in an on-line directory. Unsuspecting exhibitors who sign and return the form are then contracted into a three-year, non-retractable agreement, which could cost the exhibitor a significant amount of money, with very limited foreseeable benefits. The details are often available on the form itself, but are often too small and insignificant to be noticed. It is always wise to really the small print before signing a contract, and if the information is impossible to read then the contract should not be signed. These publications have no connection with SEMI or any of our events, and it is important that all companies are made aware of this. 

Should you receive any communication from the Expo-Guide and Fairguide.com or related company, please IGNORE THEM COMPLETELY and DO NOT COMMUNICATE WITH THEM IN ANY WAY.
