New Standards Approved During the North America Fall Meetings 2024
By Laura Nguyen, SEMI
The North America Fall Standards Meetings took place from November 4-7, 2024 at SEMI HQ in Milpitas, California, where nine Technical Committees and over 40 Task Forces engaged in various standardization activities, including the adjudication of three new standards. These advancements represent a significant milestone for the SEMI Standards Program, addressing key challenges in MEMS manufacturing, semiconductor facility planning, and 300 mm wafer handling.
SEMI Draft Document 7150: Guide to MEMS Manufacturing Readiness Levels
MEMS (microelectromechanical systems), a vital technology since their introduction in the 1960s, have faced commercialization challenges due to fragmented development approaches and a lack of standardized practices. SEMI Document 7150 addresses these issues by providing a structured framework with clearly defined readiness levels to streamline MEMS development from conception to high-volume production. The guide emphasizes standardized processes and best practices to help MEMS development teams meet performance, cost, quality, and time-to-market goals. By reducing risks and promoting efficiency, it aims to accelerate innovation and commercialization in the MEMS industry. This critical standard, developed by the joint efforts of the MEMS and Sensors Industry Group (MSIG) Manufacturing Working Group and the SEMI Standards MEMS Task Forces, was reviewed and approved by the MEMS/NEMS North America TC Chapter held on November 7, 2024. Currently under Procedural Review and if approved, we can expect a newly published standard early next year.
Facility planning for semiconductor manufacturing is evolving, with digital tools like Building Information Modeling (BIM) becoming essential for optimizing fab layouts and equipment installation. SEMI Document 6628 introduces the Facilities Data Package (FDP), a standardized format for creating 3D BIM models of semiconductor equipment.
This guide specifies utility connection details, equipment dimensions, and usage data (idle, typical, and maximum), enabling fab owners, engineers, and equipment suppliers to streamline planning, design, and installation processes. By adopting this standardized approach, semiconductor manufacturers can leverage digital twins to enhance efficiency, reduce costs, and optimize facility.
The SEMI BIM for Semiconductor Capital Equipment Task Force, initially led by Applied Materials and now Arcadis by DPS Group, began over a decade ago. Seeing this standard reach completion is a significant achievement. In its final ballot, the document received no negative votes. This critical standard was reviewed and approved by the Facilities North America Technical Committee Chapter on November 5, 2024. Currently under Procedural Review and if approved, we can expect a newly published standard early next year.
SEMI Draft Document 6896: Specification for 300 mm Film Frame FOUP (FFF)
Traditionally, semiconductor back-end processing lines have relied on metal-based open cassettes for wafer film frame handling. However, as silicon devices became more sensitive to particles, the demand for sealed containers similar to those used in front-end processes grew. In 2021, the SEMI Japan 300 mm Tape Frame PI&C Task Force addressed this need, leading to the publication of SEMI E184 and SEMI E185. These standards introduced sealed containers based on the 300 mm FOUP (Front Opening Unified Pod) concept, originally outlined in SEMI E47.1.
Building on this progress, SEMI has developed a new standard, SEMI Draft Document 6896, which establishes the basic physical dimensions for the Film Frame FOUP (FFF). The FFF is a smaller, lightweight, enclosed carrier designed specifically to transport and store 300 mm film frames, as defined in SEMI G74. The FFF supports a 10 mm pitch with a 13-capacity configuration and copies many features from the wafer FOUP, ensuring compatibility with existing Automated Material Handling Systems (AMHS) and equipment designs. The carrier is also sized to allow FFF load ports to be compliant with the 300 mm BOLTS interface, making it an ideal solution for applications requiring a more compact carrier.
This advancement in wafer handling technology addresses specific industry needs by optimizing transport and ensuring compatibility across diverse systems. Recently approved by the Physical Interfaces & Carriers (PIC) North America Technical Committee Chapter on November 6, 2024, the FFF standard is now under Procedural Review. With no negative votes received, the newly published standard is expected early next year if approved.
