SEMI International Standards Program Forms High-Brightness LED Standards Committee

SEMI announced today the formation of a high-brightness light-emitting diode (HB-LED) Standards Committee. The SEMI International Standards Committee approved the petition for the HB-LED Standards Committee on November 4, 2010. The Committee met for the first time on November 11 and initiated standards Task Forces on wafers, carriers, assembly and automation. The Committee and Task Forces are comprised of industry leaders in HB-LED devices, sapphire wafers, MOCVD wafer processing, and key equipment and materials suppliers to the LED industry.

The overall market for HB-LEDs will grow a remarkable 68 percent this year to reach $9.1 billion, with projections of doubling in size to $18.4 billion by 2014, according to industry analysts at Strategies in Light. This high-growth phase is currently driven primarily by LED TVs, displays, mobile phones, and other portable devices. However, the next growth phase of HB-LEDs will result from increasing demand for solid-state lighting where significant cost reductions will be required to replace conventional lighting sources. Industry analysts expect a 10- to 20-fold decrease in costs over the next five years to achieve rapid penetration of solid-state lighting into commercial and residential lighting applications. To reach those aggressive cost targets, key stakeholders in the industry have initiated the SEMI HB-LED Standards Committee, which will develop manufacturing standards to eliminate unnecessary costs, and better enable equipment and process innovation.

During its inaugural meeting, the HB-LED Standards Committee agreed to form task forces in four critical areas of LED manufacturing:
Wafers:
Unlike silicon wafers used in semiconductor manufacturing, there currently are no industry standards addressing wafer geometries, surface characteristics, wafer ID, wafer orientation, and other features, resulting in costly proliferation of wafer types and styles. The objective of this Task Force will be to analyze and develop wafer standards (starting with sapphire wafers) that will reduce the proliferation of varying wafer types on the market — thereby reducing costs and enabling manufacturers to focus on true product and process innovation.
Carriers: Wafer carrier standards will enable lower cost, higher precision, and more productive wafer handling, shipping, and processing. The Task Force is expected to develop standards for shipping carriers (used to ship the virgin wafers from the wafer supplier to the customer), automation carriers (carries the wafers through the automated tools), and process carriers (used to carry wafers into and from process tools; may be subjected to aggressive environments (chemical, liquid, thermal).
Automation: The objective of the Automation Task Force is to analyze and develop industry standards that allow low-cost, common hardware and software interfaces, and other means to enable HB-LED factories to effectively utilize multiple equipment types from multiple vendors in a highly automated and integrated fashion.
Assembly: Currently, wire bonding and other assembly steps are highly varied depending on the unique optical, thermal, and electrical requirements of today’s advanced lighting applications— resulting in higher costs and lower throughput. The objective of the Assembly Task Force is to examine industry standards — relating to issues like machine vision, device orientation, handling interface, and other areas — that will enable lower-cost, higher-throughput assembly while recognizing diversity of component types in a typical HB-LED manufacturing environment.

Participation in SEMI International Standards is free to all industry stakeholders. For additional information on the HB-LED Standards Committee, or how to join the Committee, contact Paul Trio at ptrio@semi.org.

About SEMI International Standards:
The SEMI International Standards Program, established in 1973, covers all aspects of micro- and nano-manufacturing, from wafer manufacturing to test, assembly and packaging, in the semiconductor, display, PV, MEMS/MST and related industries (now including HB-LED). Currently, there are over 800 SEMI Standards and Safety Guidelines available. More than 3,000 industry experts worldwide participate in the program, which is made up of 21 global technical committees. Visit www.semi.org/standards for further details about SEMI Standards.
