National and industry standards covering gallium arsenide, silicon carbide, and indium phosphide substrates, along with epitaxial materials, are being published in a concentrated wave, laying the foundation for scaled and orderly growth of the industry.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/zkmsemi.com\/wp-content\/uploads\/2026\/10\/inp_base.jpg\" alt=\"Indium phosphide single crystal substrate\"><\/p>\n<h2>The Industry Context for Concentrated Standards<\/h2>\n<p>Compound semiconductors cover GaAs, InP, SiC, GaN, and other materials used widely in RF, optoelectronics, and power devices. As the domestic industry scales fast, unified terminology, substrate parameter test methods, epitaxy quality evaluation, and reliability test methods are becoming urgent. The recently published standards cover substrate crystal orientation, doping type, dislocation density, and surface particles, helping Chinese makers align internationally, improve product consistency, and ease upstream and downstream procurement and acceptance.<\/p>\n<h2>Standards Drive Substrate Quality Up<\/h2>\n<p>Guided by standards, domestic GaAs, SiC, and InP substrate makers are tightening quality control across boule growth, slicing, polishing, and cleaning. Metrics such as dislocation density, micropipe density, flatness, and metal contamination now have agreed test bases, making customer qualification and trade acceptance smoother. This in turn pushes growth furnaces and back-end processing equipment toward higher precision and cleanliness, promoting quality progress across the whole chain.<\/p>\n<h2>Standards Order the Industry<\/h2>\n<p>Unified standards have a clear ordering effect on the industry. Without agreed test methods, different makers\u2019 dislocation density and flatness results differed widely, making downstream comparison difficult. After standards, substrate parameters have accepted test bases, procurement acceptance and quality arbitration are smoother, and low-price, low-quality products are kept from disrupting the market. Standards also push makers to benchmark key metrics against international leaders, forcing upgrades in growth, dicing, polishing, and cleaning equipment. A mature standards system marks the industry\u2019s shift from fragmentation to concentration and from scale to quality.<\/p>\n<h2>What the Standards Cover<\/h2>\n<p>The newly released standards address a broad range of substrate attributes: crystal orientation and off-angle, conductivity type and doping specification, carrier concentration, dislocation and micropipe density, surface roughness and particle counts, and packaging and handling rules. They also define standardized test methods so that measurements taken at different producers are comparable. For epitaxy, standards cover layer thickness, doping profile, interfacial defect levels, and surface morphology. When buyers and suppliers all reference the same test method, negotiations over lot acceptance become faster and less contentious, which in turn reduces transaction costs across the supply chain.<\/p>\n<h2>Global Alignment and Trade Implications<\/h2>\n<p>As Chinese compound semiconductor production scales, alignment with international standards matters for export and for supplying multinational device customers. National standards that mirror widely accepted test methods reduce the friction of cross-border qualification, while also giving domestic producers a common baseline on which to build higher-grade specifications. Over time, participation in international standard-setting allows Chinese industry to contribute to global technical consensus rather than simply following it. For equipment makers, standards also signal which process capabilities customers will expect, guiding investment in cleaning, drying, and inspection systems that meet the new cleanliness and repeatability requirements.<\/p>\n<h2>Outlook for Standardization<\/h2>\n<p>Looking ahead, the compound semiconductor standards system will continue to mature, covering materials, epitaxy, devices, and reliability across the whole chain. Unified standards help domestic firms standardize production, improve consistency, and enter international markets more easily. As standards land, wafer cleaning, inspection, and other supporting equipment must meet higher cleanliness and repeatability requirements. Domestic equipment firms that actively participate in standard and reliability validation will strengthen their position in the domestic supply chain and grow alongside material producers, turning standards into a driver rather than a barrier. When test methods are harmonized, smaller domestic producers can compete on real quality rather than on opaque specifications, and buyers can consolidate their supplier lists with confidence. Over time, this reduces transaction costs across the industry and encourages investment in higher-grade production. For equipment makers, the tightening of cleanliness and repeatability requirements inside the standards creates a clear roadmap for product development and qualification. In practical terms, this means substrate and equipment makers can invest with confidence, because they know the specifications their products must meet. Over time, a mature standards environment also reduces the risk of trade disputes and technical barriers, since Chinese products are measured against the same methods used globally, making it easier to enter overseas supply chains alongside domestic ones. For smaller producers, common standards level the playing field because quality can be demonstrated objectively, reducing the advantage of larger incumbents and allowing innovative new entrants to compete on measurable performance. As the compound semiconductor industry continues to scale, a stable standards framework will be one of the quiet enablers that allows domestic supply chains to operate efficiently and to trade with confidence. For the equipment sector, this clarity reduces development risk and accelerates time-to-market for new cleaning, drying, and inspection tools.<\/p>\n<h2>Who Writes the Standards and Why<\/h2>\n<p>Compound semiconductor standards are typically developed by national standardization bodies, industry associations, and working groups that bring together substrate makers, device manufacturers, and research institutes. The process is deliberate: proposed methods are tested in multiple labs to ensure reproducibility before being published. For buyers, this means they can specify materials with confidence that two suppliers\u2019 measured dislocation densities are comparable. For smaller domestic producers, common standards also level the playing field, because quality can be demonstrated objectively rather than through marketing alone. As the industry matures, standards increasingly move from material properties toward device reliability and application-specific requirements, which further professionalizes the supply chain.<\/p>\n<h2>Opportunities for Equipment Suppliers<\/h2>\n<p>The maturing standards system sets clearer cleanliness and repeatability requirements for wafer cleaning, spin drying, and inspection equipment. As a domestic semiconductor equipment company, Hebei Zhongke Microelectronics Co., Ltd. offers a VGF crystal growth furnace, a wafer unloading table, a fully automatic single-wafer cleaning machine, an InP cleaning machine (SQX-150-5Y1D), and wafer inspection lamps (QG-150\/QG-250). These help compound substrate makers organize production to the new standards, improving wafer appearance and cleanliness consistency and accelerating the entry of domestic substrates into high-end supply chains.<\/p>\n<p>A mature compound semiconductor standards system is an important sign of an industry coming of age.
