  • AIRBORNE MOLECULAR CONTAMINANTS

    Airborne molecular contamination (AMC) impacts semiconductor fabs and cleanrooms.  It is sometimes referred to as chemical contamination. Every material introduced into a cleanroom is a potential source of airborne molecular contamination (AMC).  AMC can cause changes in a wafer’s electrical properties at the parts-per-trillion (ppt) level in air.  This contamination must be taken very seriously.  Volatile Organic Compounds (VOC) are present even in clean production environments.   Airborne contaminants reduce yield-quality, impact tools, and are costly when not monitored. 

    Our solutions also include:

    MULTI-MAX AMC MONITORING SOLUTION

    You can spend a long time looking for Airborne Molecular Contaminants (AMCs) when the catastrophic product performance or yield loss is discovered at your device final test stage; or you can deploy our Multi-Max AMC to locate and to monitor these invisible defect generators, commonly found lurking in and around equipment, personnel, wafer carriers, and cleanroom bays.

    In today’s advanced semiconductor processing, the residual gases, vapors and chemicals emanating from the various materials, accelerated processing operations, and substrate storage and transport have become a critical concern. The International Technology Roadmap for Semiconductors (ITRS) now highlights AMC contamination as a key technical challenge in achieving and sustaining low defect rates on devices.

  • ELECTRONIC GAS

    Electronic gases and semiconductor gases are process gases used in electronic manufacturing. The electronic gases include pure gases and gas mixtures which are specially configured for specific manufacturing processes.  Electronics gases must be high purity gases. Precise gas delivery is at the core of semiconductor fabrication.  Many gases must be delivered to produce critical features on silicon wafers. These are electronic specialty gases (ESG). Electronic gases are important because they create the chemical reactions needed to shape the semiconductor’s electrical properties.  These gases include nitrogen, oxygen, argon and hydrogen.

    Our TIGER OPTICS™ Cavity Ring-Down Spectroscopy trace gas analyzers have supported the semiconductor industry and other micro-electronic manufacturing sectors.  Based on their superior sensitivity, great stability and unparalleled uptime, and free of periodic maintenance, with no moving parts or consumables they are the ideal choice for semiconductor fabs. SEMI F-112 designates CRDS as the standard in determining moisture dry-down characteristics of ultra-high-purity gases and their respective delivery systems.

  • LITHOGRAPHY

    Vacuum Ultraviolet (VUV) lithography is a process used in semiconductor manufacturing to create tiny features on semiconductor wafers using extreme ultraviolet light. Quadrupole mass spectrometers can be used in VUV lithography to monitor the purity of gases used in the lithography process.

    By monitoring the gas purity with a quadrupole mass spectrometer, VUV lithography manufacturers can quickly detect any impurities that may be present in the gas stream and take corrective action to ensure the quality of the lithography process. This can help to improve the yield and quality of the final semiconductor product.

  • MOLECULAR BEAM EPITAXY (MBE) MONITORING

    Molecular Beam Epitaxy (MBE) is a technique used in materials science and semiconductor device fabrication to grow thin films of various materials with extremely precise control over thickness and composition. MBE is a type of vapor deposition process, in which the materials are evaporated in a vacuum chamber and deposited onto a substrate, typically a single crystal wafer, to create a thin film.

    Our EXTREL™ Quadrupole Mass Spectrometer are commonly used in Molecular Beam Epitaxy (MBE) to monitor and control the quality of the deposited films. The high vacuum environment of the MBE chamber, along with the controlled deposition rate and composition, ensure that the deposited films have high purity and are free from contamination.  However, it is still important to monitor the gas-phase environment in the MBE chamber during the deposition process to ensure that the deposited films have the desired composition and properties. This is where quadrupole mass spectrometry comes into play.

  • PROCESS CONTROL

    It’s one thing to be monitoring and have high confidence in your high purity bulk and specialty gases at the post-purifier stage but a lot can change as that same gas then travels through the various fab distribution systems and arrives at the equipment or process chamber. Unless you are monitoring close to the substrate or in the process chamber exhaust, there is risk that high partial pressures of moisture are present during processing, resulting in defects causing yield loss and reliability issues. 

    Hydrogen fluoride is essential to the semiconductor process. Able to operate in a pressure range from 50 Torr to 15 psig, the TIGER OPTICS™ HALO™ RP trace level analyzer provides users with the unmatched accuracy, reliability, speed of response and ease of operation.  The Halo RP is available for two different analytes, H2O and HF, to ensure that your product is protected from all harmful molecules.  Ideal for gas quality control, research & development, semiconductor process tools, and UHP ammonia and high-brightness LED.

    • CRDS Trace-Level, Low-Pressure Moisture Analyzer TIGER OPTICS™ HALO QRP™
    • CRDS Reduced-Pressure, Trace-Level Analyzer TIGER OPTICS™ HALO RP™
  • PLASMA AND CVD PROCESS MONITORING

    Plasma Etch, Chemical Vapor Deposition (CVD) and Plasma-Enhanced Chemical Vapor Deposition (PECVD) applications require a thorough understanding of the complex chemistries involved in the processes. Also critical to the processes is the ability to monitor low-level components.

    Our EXTREL™ Quadrupole Mass Spectrometer can be used in PECVD to monitor the gas-phase environment in the plasma reactor during the deposition process. This is important because the gas-phase environment can affect the composition and quality of the deposited thin films. By measuring the partial pressure of various gases in the plasma reactor, the quadrupole mass spectrometer can provide information on the composition of the gas-phase environment and can be used to adjust the deposition conditions to ensure the desired film properties.
