Process technology for production lines.
Independent technical consulting for wet-chemical processes and production equipment in semiconductor, IC substrate and PCB, solar and energy storage manufacturing.
What I work on
Open a layer to see the work behind it and what you get at the end.
The work
Development of SC1, SC2, DHF and RCA-type cleans, HF, HNO3 and KOH etching, and ozone-based treatment of etched surfaces. Process control from lab recipe to pilot line. Additive chemistry for flow batteries and texturing.
What you get
A documented process that holds its window in production.
The work
Tracing particles, metals and defects across chemistry, tool and cleanroom environment. Surface analysis with AFM, XPS, Raman spectroscopy, ellipsometry and four-point probe. Safety (EHS) management under the EU REACH Regulation.
What you get
The cause identified, the evidence documented and corrective actions defined.
The work
Line specification, functional and equipment testing, safety sign-offs for HF, HNO3 and KOH chemistry, integration of facilities and automation, and ramp-up of turnkey production lines.
What you get
A line that runs to specification, with a documented handover.
The work
Transfer from pilot to turnkey production, training of engineers on process and operation, and process documentation with ISO-aligned standardization.
What you get
A team that runs the process without me.
The work
Portfolio and roadmap definition for industrial equipment and process technology, based on market analysis and customer requirements. Specifications, product lifecycle management and OPEX/CAPEX planning.
What you get
A prioritized roadmap and specifications your development team can build on.
The work
Global product strategies and market entry, key account management and technical customer support in EMEA, India, the Middle East and China, from proposal and contract negotiation to project hand-over.
What you get
A market entry plan and qualified customer relationships.
The work
Technical and economic evaluation of turnkey and energy storage projects, make-or-buy analyses and business cases for investors.
What you get
A decision basis you can defend.
Dr. Maher Izaaryene
PhD chemist, wet-clean and surface-process development
For more than 15 years I have developed, scaled and commissioned wet-chemical cleaning, etching and surface-treatment processes for semiconductor, wafer and advanced-materials manufacturing. I led an international R&D team at Schmid Group, took processes from concept through pilot to turnkey production, and ran global commissioning and ramp-up of production lines.
As product manager I shaped equipment and technology portfolios at Singulus (solar and semiconductor), Bischof + Klein (technical films), Balluff (optical sensors) and SAS Softec (wet-chemical and plating processes for IC substrates).
I am an inventor on several patents, including alkaline wafer texturing and ozone-based cleaning of silicon wafers after etching. With a PhD in inorganic chemistry and working in German, English, French and Arabic, I advise producers, equipment makers and investors on process, equipment and technology decisions.
