According to our (Global Info Research) latest study, the global Ultra Low-K Film market size was valued at US$ 106 million in 2025 and is forecast to a readjusted size of US$ 201 million by 2032 with a CAGR of 9.6% during review period.
In 2025, sales of ultra-low-k films reached 826,000 units, with an average price of $125 per unit.
Ultra-low-k (k < 2.5) films typically refer to nanoporous SiCOH or organic polymer materials, primarily used in back-end processes (BEOL) of advanced integrated circuits (ICs) as interlayer insulators (ILDs) to reduce interconnect delay, power consumption, and crosstalk. They are used in nanoscale chips, introducing micropores between copper lines to approximate the dielectric constant of air.
The core raw material for ultra-low dielectric constant (ULK) films is organosilane precursors (such as diethoxymethylsilane (DEMS), trimethylsilane (TMCTS), and tetraethoxysilane (TEOS). These precursors are prepared from high-purity silicon powder, methanol/ethanol, etc., via Grignard reactions or direct synthesis methods. The technology has extremely high barriers to entry, and currently, the supply is mainly monopolized by a few companies such as Merck (Germany), DuPont/Dow (USA), and Shin-Etsu Chemical (Japan). Pore-forming agents are another key raw material, typically thermally unstable organic polymers (such as norbornene and acrylates). They need to decompose and volatilize at specific temperatures to form nanopores, and their molecular structure design directly affects porosity and pore size distribution. In addition, high-purity carrier gases (helium, nitrogen), catalysts, and UV curing equipment are also indispensable. Domestically produced precursors still lag behind imported products in terms of purity and stability, leading to a reliance on imports for high-end ULK materials.
In the cost structure of ultra-low dielectric constant films, raw material costs account for the largest proportion (approximately 50-60%), with organosilane precursors accounting for over 70% and pore-forming agents accounting for 20-30%. Equipment depreciation and maintenance costs account for approximately 20-25%, as PECVD and UV curing equipment must be imported from international equipment manufacturers such as Applied Materials (AMAT) and Lam Research, with each unit costing millions of US dollars. R&D and technology licensing fees account for approximately 10-15%, including patent licensing (such as the patent pools of Applied Materials' Black Diamond and Dow SiLK) and process development costs. Production and operating costs (cleanroom, energy consumption, and labor) account for approximately 10%. Due to technological monopolies and patent barriers, the gross profit margin of ultra-low dielectric constant films is extremely high (approximately 60-80%), but R&D investment is enormous, with a single production line investment reaching hundreds of millions of RMB.
