The partner client is NANO PRECISION GmbH, a high-end semiconductor precursor group headquartered in Munich, Germany. The company specializes in R&D and production of noble metal organic precursors for semiconductor ALD (Atomic Layer Deposition), OLED panels and high-end sensors. It serves Europe’s three major semiconductor giants and world-leading panel manufacturers, complying with SEMI F57 electronic-grade standards and EU REACH regulations requiring zero detection of Substances of Very High Concern (SVHC). It is a typical tech-driven mid-to-high-end overseas client.
The client purchases 15 kg of ultra-high-purity platinum(II) acetylacetonate (Pt(acac)₂) annually as the core precursor for platinum thin-film deposition in semiconductors. Its requirements include: purity ≥99.995% (5N grade), metallic impurities ≤0.5 ppm, moisture ≤30 ppm, narrow particle size distribution (D50=5–8 μm), and zero chloride residue. Previously, the client sourced products from Johnson Matthey Germany at a unit price of RMB 380,000 per kilogram, with long lead times (8–12 weeks) and high minimum order quantities (5 kg per batch). Faced with cost pressure and supply chain security risks, the client shifted to Chinese customized suppliers. However, three contacted domestic manufacturers failed to simultaneously meet four core customized indicators: ultra-high purity, precise particle size control, chloride-free residue, and export control compliance. The client ultimately entrusted HiSiaddi with full responsibility for customized R&D, process implementation and compliant export.
1.
High Purity Barrier: Difficult to achieve stable 5N-grade purity with high risk of excessive impurities Conventional industrial-grade platinum(II) acetylacetonate only reaches 99.9%–99.95% purity, with metallic impurities (Fe, Cu, Ni, Cr) generally ≥2 ppm. The client mandates 5N-grade purity (99.995%) and impurities ≤0.5 ppm. Domestic manufacturers lack mature high-purity purification processes integrating multi-stage recrystallization, ion exchange and inert gas protection, making stable compliance unachievable.

3.
Difficult Particle Size Control: No mature solutions for customized microcrystals with narrow distribution The client requires uniform microcrystals with D50=5–8 μm and span <1.2 to support precise ALD deposition. Domestic manufacturers mostly adopt crude crystallization processes, yielding particles of 10–30 μm with wide distribution and severe agglomeration, failing to meet precise feeding requirements of semiconductor equipment.
4.
5.
Stringent Chloride-Free Requirement: Conventional processes cannot fully eliminate chloride to below 10 ppm Chloroplatinic acid is used as the raw material for synthesizing platinum(II) acetylacetonate. Conventional water washing leaves chloride residues ≥50 ppm, while the client’s threshold is <10 ppm to prevent chloride-induced wafer corrosion. Domestic manufacturers lack core technologies including deep complexation dechlorination and vacuum pyrolysis.

7.
Export Control Compliance: Dual-use item license & end-user review Since 2023, platinum(II) acetylacetonate with purity ≥99.99% has been included in the Catalogue of Controlled Dual-Use Items and Technologies Requiring Export Licenses. Export procedures require an export license plus End-User/End-Use Declaration (EUD), together with end-user review by the Ministry of Commerce. Ordinary factories lack precious metal export qualifications and experience in dual-use item declaration, making compliant export impossible.

9.
Contradiction Between Customization & Mass Production: Low volume (15 kg/year) with stringent requirements discourages factory investment The client’s annual demand of only 15 kg falls under low-volume ultra-precision customization, requiring dedicated high-purity production lines, cleanrooms and precision testing equipment with heavy upfront investment. Domestic manufacturers prioritize mass production of standard products, resulting in low enthusiasm for small-batch customization, high quotations and extended lead times.

HiSiaddi assembled a team of PhDs specializing in noble metal organic synthesis, semiconductor material engineers, high-purity process specialists and dual-use item compliance officers. It collaborated with Sino-Platinum Metals Co., Ltd., a leading domestic high-purity precious metal enterprise, to conduct customized R&D, completing full-process customized delivery within 3 months via a five-step workflow: Technical Breakthrough → Process Optimization → Pilot Verification → Mass Production Implementation → Compliant Export.
1. Reconstructed High-Purity Synthesis Process: 5N-grade purity & impurities ≤0.5 ppm
· Raw material selection: Adopt 99.999% ultra-high-purity platinum powder to prepare chloroplatinic acid and reduce impurities at the source.
· Optimized complexation-reduction: Precisely control pH=8.5±0.2 and temperature at 75°C under nitrogen inert protection to avoid doping of metallic ions.
· Multi-stage recrystallization: Adopt mixed anhydrous ethanol and acetonitrile solvents with three rounds of low-temperature (-10°C) recrystallization to remove trace organic impurities.
· Deep impurity removal via ion exchange: Strong acid cation exchange resin reduces metallic impurities from 2 ppm to ≤0.5 ppm, attaining 5N-grade purity.
1. Precise Microcrystal Particle Size Control: D50=5–8 μm, narrow distribution without agglomeration
· Crystallization kinetic regulation: Add trace surfactant (0.1%) to control nucleation rate.
· Gradient cooling crystallization: Cool uniformly from 60°C to 25°C at a rate of 1°C/h to avoid oversized particles and agglomeration from rapid crystallization.
· Aseptic gas flow crushing & sieving: Post-crystallization crushing under nitrogen protection to target particle size, followed by sieving through a 2000-mesh sterile screen. Final D50 reaches 6.2 μm with span of 1.08, fully matching ALD process requirements.
1. Deep Dechlorination Technology: Chloride ≤8 ppm with zero residual risk
· Complexation dechlorination: Add acetylacetone at 1.2 times the equivalent to form soluble chloride complexes.
· Vacuum pyrolysis dechlorination: Treat at 120°C under high vacuum (-0.09 MPa) for 4 hours to thoroughly eliminate residual chloride.
· Closed-loop ion detection: Test each batch via ion chromatography to guarantee chloride ≤8 ppm, well below the client’s 10 ppm limit.
1. Full-Process Compliance Handling for Dual-Use Items
· Qualification coordination: Engage Sino-Platinum Metals to provide precious metal export qualifications and dual-use item production filings.
· License application: Prepare technical specifications, purity test reports, End-User Declaration (EUD) and end-use certifications to submit an export license application to the Ministry of Commerce.
· End-user review assistance: Support the client in submitting corporate qualification documents of NANO PRECISION GmbH, semiconductor use certifications and non-military use commitments, successfully passing the Ministry of Commerce’s end-user review.
