Laser trimming is a crucial semiconductor technology that precisely adjusts photonic Integrated Circuits (PICs) directly on the wafer, where the tight tolerances are essential. This process significantly reduces performance variations before dicing and packaging, improving uniformity across devices and lowering rework rates. By permanently correcting deviations in the early wafer or die stage, laser trimming ensures PICs meet stringent performance specifications at lower operating temperatures, enhancing their quality and longevity. This proactive approach optimizes individual device performance and contributes to the robustness of entire systems. The result is increased manufacturing yields and cost-effectiveness.
