Equipment (Back End) companies

25 companies in the Equipment (Back End) part of the semiconductor & AI value chain — Back-end equipment handles everything after front-end processing — testing finished wafers and individual dies, dicing, assembly, and final packaging. Automated test equipment (ATE) is led by Advantest and Teradyne, whose testers qualify every high-bandwidth memory stack and AI accelerator. Probe cards (FormFactor, Technoprobe), dicing and grinding (DISCO), and advanced assembly tools (BESI, ASMPT) round out a segment whose importance has grown sharply as advanced packaging becomes a primary performance lever.
