PI Unveils Innovative Miniaturized Alignment Engine
Parallel piezo aligners with fly height sensors are set to revolutionize the testing process of photonic integrated circuits (PICs). This new platform promises to expedite wafer testing, thereby enhancing the overall efficiency of production.
Groundbreaking Technology for Wafer-Level Testing
PI (Physik Instrumente) has introduced a cutting-edge technology platform tailored for electro-optical wafer-level testing. This impressive system is designed to facilitate the simultaneous validation of both electrical and optical device functions, a critical aspect in high-volume production scenarios. By seamlessly integrating high-density electrical probing with automated photonic alignment, the platform showcases a compact architecture that is fully compatible with Automatic Test Equipment (ATE).
Optimizing Testing with Parallel Operations
Engineered for scalability, this innovative platform supports the parallel operation of multiple miniaturized alignment engines across a single wafer. This feature allows for simultaneous electro-optical probing at various test sites, thus significantly increasing throughput while reducing testing costs. The compact design of this architecture makes it practical to deploy several aligners within a single testing setup. This capability is essential for EPIC manufacturers aiming to transition from traditional sequential lab-style alignment to repeatable and efficient wafer-level testing.
Introducing FAU Ranging for Enhanced Accuracy
One of the standout features of this platform is the FAU ranging technology. This method employs interferometry-based fly-height measurement to accurately gauge the fiber-to-wafer distance at crucial points without necessitating additional hardware or space. This functionality is pivotal for maintaining stable probing and ensuring reliable optical coupling. The implementation of FAU ranging additionally opens avenues for future technologies like trench-based photonic edge coupling, potentially conserving wafer real estate and decreasing device costs.
Insights from PI Leadership
Dr. Markus Simon, who oversees Strategic Innovation and Technology Management at PI, expressed the significance of FAU ranging by stating, "With FAU ranging, we pave the way for trench-based photonic edge coupling, saving wafer real estate, reducing device costs, and unlocking new design freedom for EPIC manufacturers." His insights highlight the innovative potential behind this new alignment engine.
