  • Using VPD ICP-MS to monitor trace metals on unpatterned wafer surfaces
    . The analyst must be skillful in order to achieve proper collection and complete wafer surface coverage. Inherent problems include sample preparation precision, total surface coverage, wafer-edge contamination, and actual sample loss. With the advent of 300-mm wafers, manual scanning of the wafer...
  • Characterizing organic impurities in semiconductor-grade hydrogen peroxide
    of organic impurities in high-purity hydrogen peroxide used in wet cleaning processes. The amount of organic contaminants in hydrogen peroxide is well within the parts-per-million concentration range, and total organic carbon (TOC) values around 15 ppm are considered acceptable by many users. Organic...
  • Characterizing effluents from PECVD, plasma etch processes
    standard liters, are as follows: Total equivalent Cl emit-ted 0.7263 +- 0.0063. Total equivalent Br emit-ted 0.1797 +- 0.0021. Total equivalent Cl in 0.9000. Total equivalent Br in 0.2000. Cl closure 81 +- 1%. Br closure 90 +- 1%. As in the case of the CVD process discussed above, the loss...
  • TA-MS Connection Optimisation and Improved Data Interpretation (.pdf)
    . TA equipment can control the mass spectrometer and reads the mass. spectrometer data through an RS232 connection. Or. The mass spectrometer can read the TA equipment data, sample. temperature and weight loss for example. For detailed mass spectrometer studies it is recommended to read the. TA...
  • Is fungal treatment beneficial?
    chips are above 97%. It is evident that there was minimal fibre weight loss induced by fungal treatment, aging the chips or their chemical treatment. TABLE I. Chemithermomechanical pulping yield. Aging Period (weeks) Control Untreated Chips Cartapip 97(R) Treated Chips 0 98.2±2.2%...
