Thin wafer market seen topping $19 billion by 2030

The Business Research Company says the thin wafer market is on track to exceed $19 billion by 2030, driven by demand for smaller consumer electronics, advanced semiconductor packaging, and chips used in automotive, AI and 5G systems. Asia-Pacific and China are set to lead growth, while Shin-Etsu Chemical is projected to remain the top supplier in 2025.

Why it matters: - Thin wafers are becoming a core enabling technology for smaller, faster and more power-efficient chips across consumer devices, vehicles, AI systems and telecom networks. - The market’s growth points to rising demand for advanced semiconductor manufacturing capacity and packaging technologies. - The segment is expected to move from a niche slice of the semiconductor industry to a market worth more than $19 billion by 2030.

What happened: - The Business Research Company published its Thin Wafer Market Global Market Report 2026 – Market Size, Trends, and Forecast 2026-2035. - The report projects the thin wafer market will exceed $19 billion by 2030. - The market is forecast to grow at a 9% compound annual growth rate through 2030. - Asia-Pacific is projected to be the largest regional market in 2030. - Shin-Etsu Chemical Co. Ltd. is forecast to lead the market in 2025 with about 4% share. - The top 10 players are expected to hold 22% of the market in 2025.

The details: - Thin wafers account for about 2% of the broader semiconductor and related devices market, which is projected to reach about $950 billion by 2030. - Thin wafers represent about 0.3% of the wider electrical and electronics industry, which is projected to reach $5,579 billion by 2030. - Demand for compact consumer electronics is a major growth driver. - Smartphones, wearables, tablets and AR/VR headsets need chips that are thinner and more powerful. - Thin wafers support lighter device designs, better heat dissipation and denser component integration. - This demand is expected to add about 2.4% annual growth to the market. - Advanced semiconductor packaging and 3D integration are another key driver. - 3D integrated circuits, wafer-level packaging and chiplet architectures depend heavily on ultra-thin wafers. - This trend is expected to add about 2.2% annual growth. - Semiconductor demand from automotive, artificial intelligence and 5G is also expanding the market. - Electric and autonomous vehicles, AI processors, industrial IoT and next-generation telecom networks are pushing adoption. - This demand is expected to add about 2.0% yearly growth. - By wafer diameter, the market includes 125 mm, 200 mm and 300 mm wafers. - The 300 mm segment is projected to dominate in 2030 with about $10 billion in value, or half the market. - Growth in 300 mm wafers is tied to specialized semiconductor manufacturing, cost-effective production for analog and power devices, and better wafer thinning methods. - By process type, the market includes temporary bonding and debonding, and carrier-less or taiko processes. - By technology, the market includes wafer grinding, polishing and dicing. - By application, thin wafers are used in MEMS, CMOS image sensors, RF devices, LEDs, interposers, logic circuits and other uses. - Asia-Pacific is projected to reach $9 billion in 2030, up from $6 billion in 2025, equal to a 10% CAGR. - China is projected to be the largest single-country market in 2030 at $4 billion, up from $3 billion in 2025, for an 8% CAGR. - China’s growth is linked to semiconductor self-sufficiency efforts, rising integrated circuit output and demand from automotive and telecom markets.

Between the lines: - The market is moderately fragmented, with high capital costs and precision manufacturing requirements limiting new entrants. - Competitive advantage depends on wafer flatness, mechanical strength, low defect rates, packaging compatibility and high-volume manufacturing efficiency. - The report’s company rankings show a crowded field, but no single player dominates the market. - Shin-Etsu Chemical’s lead reflects strength in ultra-thin, polished and epitaxial silicon wafers and engineered substrates. - Infineon Technologies AG introduced what it called the world’s thinnest silicon power wafer in October 2024, at 20 micrometers. - That development signals how ultra-thin wafers are being pushed further for power efficiency, AI-focused power delivery and high-volume production. - The report identifies silicon carbide and gallium nitride thin wafers as an important growth area for power electronics.

What's next: - The 300 mm, 200 mm and 125 mm wafer segments are expected to add more than $6 billion combined by 2030. - The 300 mm segment is projected to add $3 billion, the 200 mm segment $2 billion and the 125 mm segment $1 billion from 2025 levels. - Future growth is expected to come from advanced fabrication plants, high-density chip manufacturing, wafer-level packaging and heterogeneous integration. - Companies are likely to keep investing in precision thinning, temporary bonding and debonding, and automation to improve yield and efficiency. - The report highlights continued opportunity for suppliers tied to AI, high-performance computing and advanced packaging.

The bottom line: - Thin wafers are moving from a specialist input to a strategic layer in the semiconductor supply chain, with Asia-Pacific and China set to capture much of the next wave of demand.
