Key Responsibilities
- Support optical interconnect integration using 2.5D and 3D advanced packaging approaches.
- Understand and generate package design layouts, process‑flow concepts, test vehicle plans, and validation strategies.
- Coordinate fabrication, assembly, and integration of optical interconnect test vehicles with internal teams and external partners.
- Develop advanced package‑level and wafer‑level optical interconnect solutions for Co‑Packaged Optics (CPO) and heterogeneous integration platforms.
- Perform optical simulation and analysis to assess coupling loss, alignment tolerance, package‑stack effects, and interface‑related optical performance.
- Design and evaluate optical coupling structures, including grating‑coupler, edge‑coupler, lens‑assisted, and fiber‑array‑based interfaces.
Requirements
- Knowledge of optical coupling mechanisms, optical loss sources, alignment tolerances, and package-induced optical performance variations.
- Familiarity with photonic integration platforms such as Silicon Photonics (SiPh), Indium Phosphide (InP), and Thin-Film Lithium Niobate (TFLN), including edge-coupler and grating-coupler interfaces.
- Knowledge of wafer-level and package-level fabrication processes, including lithography, plasma etching, wafer thinning, bonding, molding, and dicing processes.
- Familiarity with optical simulation and analysis tools for evaluating coupling efficiency, alignment sensitivity, and optical interface performance.
- Familiarity with microscope-based inspection, metrology, and laboratory characterization.
- Ability to support process integration activities, and collaboration with internal teams and external partners.
