I. Client Background

The client is Elektron Chemie GmbH, a high-end electronic chemical enterprise headquartered in Munich, Germany, focused on R&D and production of high-purity solvents for semiconductor wafer cleaning, photoresist stripping and premium electronic slurry manufacturing. Its products are supplied to top European semiconductor and precision electronics firms, complying with SEMIC4, ISO 14644, REACH and German electronic chemical standards. It requires electronic high-purity DMI with low metal content, low particulate matter, strong batch consistency and complete compliance documentation, with an annual procurement volume of 50 tons, representing a typical high-end overseas client.

Client Pain Points: First-time procurement of Chinese DMI with zero familiarity with mainstream domestic brands, product tiers, performance differences and application scenarios. Four contacted manufacturers only promoted their own products, avoiding objective comparisons and competitor advantages, leaving the client unable to judge optimal matching products for semiconductor processes. Fearing incorrect material selection would reduce high-end product yield, the client entrusted HiSiaddi to complete research, objective evaluation and targeted recommendations for five major brands within 10 days.

II. Survey of Mainstream Domestic DMI Brands (5 Manufacturers Covering Low, Mid & High-End Tiers)
