    Expanded Semiconductor Assembly and Test Facility Database Tracks OSAT and Integrated Device Manufacturers in 670 Facilities, SEMI and TechSearch International Report

    New edition of database tracks 33% more facilities and highlights advanced packaging and factory certifications

    The new edition of the Worldwide Assembly & Test Facility Database expands coverage to 670 facilities, 33% more than the previous release, including 500 outsourced semiconductor assembly and test (OSAT) service providers and 170 integrated device manufacturer (IDM) facilities, SEMI and TechSearch International announced today. The database is the only commercially available listing of assembly and test suppliers that provides comprehensive updates on packaging and testing services offered by the semiconductor industry.

    The updated database includes factory certifications in critical areas such as quality, environmental, security and safety as well as data reflecting automotive quality certifications obtained by each site. The new edition also highlights advanced packaging offerings by each factory, defined as flip chip bumping and assembly, fan-out and fan-in wafer-level packaging (WLP), through silicon via (TSV), 2.5D and 3D capability.

    “Understanding the location of legacy packaging as well as advanced packaging and test is essential to effective supply-base management,” said Jan Vardaman, President at TechSearch International. “The updated Worldwide Assembly & Test Facility Database is an invaluable tool in tracking the packaging and assembly ecosystem.”

    “The database increases its focus on advanced packaging while highlighting conventional packaging capabilities and new test capabilities to support innovations in key end markets including automotive,” said Clark Tseng, Senior Director of SEMI Market Intelligence.

    Combining the semiconductor industry expertise of SEMI and TechSearch International, the Worldwide Assembly & Test Facility Database update also lists revenues of the world’s top 20 OSAT companies and captures changes in technology capabilities and service offerings.

    Covering facilities in the Americas, China, Europe, Japan, Southeast Asia, South Korea and Taiwan, the database highlights new and emerging packaging offerings by manufacturing locations and companies. Details tracked include:

    • Plant site location, technology, and capability: Packaging, test, and other product specializations, such as sensor, automotive and power devices
    • Packaging assembly service offerings Ball grid array (BGA), specific leadframe types such as quad flat package (QFP), quad flat no-leads (QFN), small outline (SO), flip-chip bumping, WLP, Modules/System in Package (SIP), and sensors
    • New manufacturing sites announced, planned or under construction
