High-conviction AI infrastructure names that don't fit a single thematic basket: wafer-level SiC/GaN burn-in and package test (AEHR), analog and RF specialty foundry (GFS), MEMS-based precision network timing ICs (SITM), precision power sub-systems for semiconductor etch and deposition tools (AEIS), magnetic current-sensing ICs for AI rack power monitoring (ALGM), AI edge vision SoCs for cameras and robotics (AMBA), and silicon wafer supply — the critical substrate underpinning all leading-edge AI chip fabs (SUMCO/3436.T).
