Semiconductor Production: Overview of Analytical Methods for Monitoring Critical QC Parameters
Metrohm is pleased to present a free overview of analytical methods that are used for monitoring critical QC parameters in semiconductor production.
The methods presented in this overview are used for monitoring water purity, acids in etching baths, concentration of metal salts in plating baths, and ionic impurities. Hyperlinks to numerous
Application Notes and several White Papers are embedded in this document making detailed information about most of these applications available at a single mouse click.
For easier access, the methods are structured according to the different stages in the manufacturing process from monitoring the purity of raw materials to etching, plating, wafer level packaging, encapsulation and lamination of PCBs, and finally monitoring recovery of chemicals and wastewater treatment.
The document can be downloaded free of charge from the Metrohm website.

High-speed, Sensitive,
Two-in-One Spectroscopy Due to its long history at the forefront of high- performance fluorescence research instrumentation, Horiba recognised the need for a cost- effective yet highly sensitive, workhorse instrument for spectroscopy applications across a wide variety of fields. Taking advantage of its decades of experience in fluorescence, Horiba developed a unique spectrofluorometer, the Duetta™ fluorescence and absorbance spectrometer.
As a two-in-one system simultaneously performing both fluorescence and absorbance measurements, Duetta removes the need for multiple scanning instruments. This makes high-performance spectroscopy affordable and saves valuable laboratory space. Its dual analysis also enables Duetta to automatically correct spectra for Inner Filter Effects (IFE) to ensure complete results accuracy, which is notoriously challenging with fluorescence data. Duetta can deliver true molecular fingerprints, not possible with standard spectrofluorometers.

Detect Mercury, Arsenic, and Selenium in
Environmental and Food Samples P S Analytical (PSA) provides niche analytical instruments for the determination of mercury, arsenic, selenium, antimony and bismuth in many sample matrices including environmental and food and beverage samples.
The presence of these toxic metals in their various forms is of real concern. Increasingly the determination of both total and speciated chemical forms is required and this requirement generates further analytical challenges of sensitivity, selectivity and freedom for interferences.
In addition to analytical considerations operation issues such as; ease of use, reliability and robustness as well as very affordable running costs are all important and are recognised hallmarks or the PSA brand.
Coupling Atomic Fluorescence Spectroscopy (AFS) with either cold vapour generation or hydride generation has been PSA’s core competency for over 30 years. With the addition of analyte separation capability which allows for speciation studies, PSA offers some powerful tools to help with these endeavours.
For example, the separation of; methyl mercury from inorganic mercury in water, shellfish, seaweed, dairy products, vegetables and grains; the determination inorganic arsenic from less toxic organo arsenic species in water, rice, seaweed are examples of routine applications developed for this growing area of concern.
The team is constantly developing new methods and applications to address market concerns and so if you have a sample you are interested to know more about with, PSA would love to hear from you.
With literally thousands of systems in the field today, and support networks in Europe, USA and SE Asia, PSA offers the ideal package of performance, reliability and support.
