Project Overview
Joseph Sabol, PhD
Chemical Consulting Portfolio 2
Silicon Purification - North America
A North American manufacturer of semiconductor processing technology (purification of silicon for downstream semiconductor wafers) sought help on the rate at which metal coatings would be corroded when exposed to chlorosilane gas mixtures at 350 degrees Celsius. Sabol provided thermodynamic information on estimation of free energy of reaction ΔG for various systems, identified a European laboratory to perform physical testing (to confirm corrosion/passivation predictions), and interpreted the test results.

Semiconductor Capital Equipment - North America
A North American manufacturer of capital equipment used in semiconductor wafer fabrication sought help on cleaning wafers during photoresist and etching. Sabol modeled the clean and etch bath (mixture of HF/NH3/HCl/H2O) chemistries with rigorous simultaneous equilibrium analysis (nine independent aqueous species, including activity coefficients.) Sabol also provided insight on the temperature dependence, application of Pourbaix diagrams, and use of non-aqueous solvent systems for wafer cleaning and etching.

Metal Processing - North America
A North American manufacturer of stainless steel products sought help on understanding the chemistry of mixtures of concentrated sulfuric and chromic acids, pH < −2. Sabol modeled the system with rigorous simultaneous equilibrium analysis (nine independent aqueous species, including activity coefficients) and recommended adjustment of acid input and waste output streams to produce more consistent metal product and technology for process monitoring. Sabol also supervised installation of an acetylene flame Atomic Absorption Spectrometer and operator training.

Electronic Components - North America
A North American electronics component manufacturer was experiencing product defects (crystalline oxides) and suspected impurities in its tantalum input stream. Sabol provided information on amorphous and crystalline oxide formation, characteristics of defects, possible contamination routes (e.g., iron, organic compounds, etc), analytical methodology, and raw material sourcing.

Polymer Automobile Parts - North America
A North American manufacturer of automobile parts sought help on bending and forming polymeric parts via methods other than thermal heating. Sabol provided information on the electromagnetic spectrum, absorption cross sections and their frequency and temperature dependence, other relevant molecular physical properties, polymer blends and co-polymers, cross-linking, and additives. ASTM test specifications were observed.

3-D Printing Materials - Asia
An Asian investor sought information about 2-D and/or 3-D advanced printing materials and specialty chemical technologies open and available for license, joint development, and/or investment. Sabol provided third-party leads on UV curable materials, high-performance ceramics, metal oxides and semiconductors, and multi-element/layer thin films.

Cleaning Products - North America
A North American manufacturer of cleaning products sought help on additives that would appear “invisible” to the naked eye, but that would leave a residue after a cleaning application and appear when exposed to light outside the visible spectrum (400-700 nm). Sabol provided information on dyes and dye photophysics, solubility, sourcing, and other relevant information in developing a cleaning product formulation.

Spot Test Paper - Asia
An Asian company desired entry into the aqueous ion spot-test market and sought help on the chemistry of dyes and suitable substances that would change color when exposed to the species of interest. Sabol provided information on the chemistry of ion-selective dyes, technology by which these dyes could be incorporated on to the surface of paper and other substrates, and papermaking and finishing into a marketable product.

Consumer Products - North America
A North American manufacturer of foods and over-the-counter pharmaceuticals sought help during of licencing a novel veterinary formulation (which included various amino acids) to a multi-national consumer products company, but also potentially for human topical applications. Sabol reviewed the client’s records, developed marketing materials, and prepared and lead a presentation for the licencee’s personnel.
