    Study Notes

    Micron's Memory R&D Center of Excellence in Boise

    • Micron’s memory research and development facility in Boise, Idaho, is a cutting-edge center for silicon development, fabrication, and testing.

    • The facility houses over 200,000 square feet of dedicated space, featuring a Class 100 cleanroom environment.

    • Micron has invested $15 billion in expanding the facility, with plans to add 600,000 square feet of sustainable cleanroom manufacturing space by 2025.

    • This facility focuses on researching and validating new memory technologies, with an emphasis on advanced, unreleased technologies.

    • Micron is currently deploying EUV lithography systems as part of the development of their upcoming 1-gamma and 1-delta nodes.

    • Micron uses a UF 3000 wafer probing machine to test and diagnose issues with new silicon wafers.

    • This machine allows engineers to probe individual dies with high precision through a combination of machine vision and manual input.

    Wafer Probing and Characterization

    • Micron utilizes picoprobes, which are incredibly tiny and precise tools, to test and analyze the internal functionality of dies.

    • The picoprobes allow engineers to perform detailed investigations into the inner workings of the dies, revealing insights that traditional probes cannot achieve.

    • To maximize the testing and analysis of wafers, they are often cut in half, enabling multiple engineers to inspect and diagnose issues simultaneously.

    Wafer Thinning and Slicing

    • Thinning the wafer is a crucial step in the process. Micron uses a specialized machine to thin the wafers, applying a plastic protective film and then grinding the wafer down to a specific thickness.

    • The thinned wafers are then sliced using diamond blades that are incredibly thin, akin to the width of a human finger hair.

    • This process allows for precise cutting of individual dies while adhering to the sticky backing material.

    Encapsulation and Packaging

    • Encapsulation involves packaging the dies, which involves stacking multiple dies, bonding them with exceptional precision, and attaching bond wires to facilitate soldering onto a board.

    • The encapsulated dies are then embedded within an epoxy or a mold compound to protect them during transportation and use.

    DDR5 Memory Module Production

    • After encapsulation, the dies undergo rigorous characterization testing, which verifies their functionality.

    • These tests are essential to ensure that the dies perform adequately at high speeds, meeting the demanding requirements of Micron's customers.

    • Micron utilizes a multi-stage automated PCV production line for the production of memory modules.

    • The line includes robots for pick-and-place operations, silk screening of solder paste, and various testing and inspection stages.

    • Defectively screened memory modules can undergo a manual repair process, where errors can be corrected before the next stage.

    Quality Testing and Characterization

    • Micron uses a specialized bending machine to assess the performance of packaged modules.

    • This machine simulates various environmental conditions, including hot and cold temperatures, to test the modules' durability and resilience.

    • The bending machine helps determine the variation in module performance and identify any potential problems that may arise.

    • Micron implements a multi-level quality control system to ensure the production of high-quality memory modules, with only prime-quality dies being used in their consumer Crucial branded DIMMs.

    Advanced Diagnostic Tools

    • X-ray machines are used to non-destructively diagnose potential issues in individual dies or modules.

    • Scanning electron microscopes offer an even higher level of detail, allowing engineers to scrutinize the dies at the gate and transistor level, further assisting in problem diagnosis.

    • Micron's R&D facility employs a comprehensive range of advanced testing and diagnostic tools to ensure the development and production of cutting-edge memory technologies.

    Memory Module Testing

    • Memory modules go through a heating cycle (heating, holding, cooling) before being tested
    • Modules are prepped with components on one side and tested on the other
    • Modules are tested using a CNC cutter
    • The CNC has a safety check to ensure the correct gripper is loaded for the type of module (SODIMMs, DIMMs, DDR4, DDR5)

    Long-Term Burn-In and Validation Lab

    • Micron has servers that test new memory modules for thousands of hours
    • Tests are conducted on consumer motherboards
    • They hold validation boards for various platforms to test customer complaints
    • Micron works with a range of companies, including automotive manufacturers, dishwasher manufacturers, etc. to test memory
    • Micron has a large EMI test chamber that measures radio emissions from modules to ensure regulatory compliance and limit unwanted radiation

    Module Testing

    • Micron's testing labs are often equipped with unreleased hardware, making public filming difficult.
    • The modules are tested in a test bench
    • The 24 Gigabyte modules are a "secret" and are not for sale, and the Micron representative is not allowed to provide more detail.

    Micron R&D Facility

    • Micron R&D is based in Idaho, USA.
    • It is the largest R&D facility for storage and memory products in the Western Hemisphere.
    • It has a large number of electrical panels and testing equipment.
    • The facility houses 50,000 patents related to storage and memory technologies.
    • There are "secret" 24 GB modules that were not supposed to leave the lab.
