Photoresist and Photoresist Ancillaries are materials used in the fabrication of semiconductor devices. A photoresist is a light-sensitive material that is used in the photolithography process to selectively create patterns on a surface. Photoresist Ancillaries are materials used in conjunction with the photoresist to improve the performance and yield of the process. These include developers, solvents, and strippers. Photoresist and Photoresist Ancillaries are in high demand due to the ever-increasing demand for semiconductor devices such as processors, memory chips, and other electronics. They are also used in the production of solar cells, medical devices, and other industrial processes.

The global photoresist and photoresist ancillaries market size is estimated to be USD 3.3 billion in 2020 and projected to reach USD 4.2 billion by 2025, at a CAGR of 4.8%. A photoresist is a light-sensitive chemical used to create the desired pattern on the substrate during photolithography or photoengraving. In a positive resist, the portion of the photoresist that is exposed to light becomes soluble in the photoresist developer. The unexposed portion of the photoresist remains insoluble in the photoresist developer. A negative photoresist is a type of photoresist in which the portion that is exposed to light becomes insoluble in the photoresist developer. The photoresist developer dissolves the unexposed portion of the photoresist.

Photoresists are classified broadly based on their response to a specific wavelength of light. These materials are sensitive to wavelengths 193 nm (ArF), 248 nm (KrF), 365 nm (I-line), and 436 nm (G-line). Among the mentioned photoresists, ArF is the most widely used as it provides superior resolution with low defect levels, owing to its narrow wavelength and ability to break through a 10 nm level. Antireflective coating, developer, and remover are some of the types of photoresist ancillaries that are majorly used during photolithography.

The photoresist and photoresist ancillaries market is classified based on the application as semiconductor &ICs, LCD, printed circuit boards, and others (NEMS, MEMS, sensors). Among them, semiconductor & ICs is the largest application due to the production of huge volumes of integrated circuits or chips due to the growing demand.

The photoresist and photoresist ancillaries market is studied for five regions, namely APAC, North America, Europe, South America, and Middle East & Africa. APAC is expected to be the fastest-growing regional market due to the growing chip production in Taiwan, China, Japan, and South Korea.
