Silicon Photonics Semiconductor Testing Supply Chain Obstacles at Insertion 2 for AI Processing Systems and Advanced Optical Co Packaging High Speed Infrastructure
The semiconductor testing supply chain encounters its most significant obstacle when it tries to handle the demands of silicon photonics technology. The industry encounters a major production challenge because it faces technical difficulties during the transition to silicon photonics and optical co packaging technologies. The semiconductor testing supply chain now carries the complete responsibility for both AI processing systems and all associated power testing systems According to industry report from Digitimes. In this battle chip testing reaches its most difficult point at Insertion 2 which specialists consider to be the main challenge preventing progress from laboratory testing to manufacturing operations.
Company integration methods lead to Insertion 2 difficulties which arise from TSMC's implementation of their systems. SoIC technology vertical stacking allows electronic and photonic integrated circuits to stack vertically. A test that requires both sides of a wafer to undergo testing needs the system to function while light must remain completely turned off. The testing process now takes more time and experiences more errors because the current market lacks automated systems that can handle both signal conditions. For semiconductor manufacturers this stage has become a literal black hole which will diminish market enthusiasm unless both costs and testing efficiency reach economies of scale.
Equipment and interface manufacturers double production development work to handle their mass production requirements. Advantest and Teradyne team up with FormFactor and Hanmin Test to establish their presence in the new market according to their partnership with these interface specialists. Advantest pushes its Triton solution which was developed together with FormFactor to establish a photonic IC testing standard for Insertion 1. Insertion 1 and Insertion 3 currently have automated protocols which function at a mature level but Insertion 2 remains the only exception to this pattern.
The danger level for CPO packaging operations reaches an extremely high level according to analysts who study this field. The industry now uses shift left testing methods because defect discovery after assembly becomes unacceptably expensive. Phased verification serves as the main defense mechanism companies use to protect their profit margins against the expensive chip failure costs which these advanced chip designs generate.
Supply chain sources warn that testing companies will make dangerous equipment testing decisions if the industry fails to fix its power on testing and light off testing equipment problems. To maintain ship schedules firms might bypass the Insertion 2 phase entirely during early production runs to save time while they face increased defect rates at the final Insertion 3 stage. This tactical maneuver highlights just how critical the stability and accuracy of high speed transmission environments have become for the future of AI infrastructure.
