What Kempur Microelectronics does

Kempur Microelectronics (北京科华微电子材料有限公司) is a Chinese photoresist manufacturer founded in August 2004 as a Sino-US joint venture by Chen Xin, a semiconductor materials veteran returning from a US photoresist firm. The company develops and produces advanced photoresists — including KrF deep UV (248nm), I-line, G-line, UV wide-spectrum, thick film, lift-off, BP, and discrete-device negative series — alongside supporting reagents such as developers and strippers. These materials are consumed in lithography processes for integrated circuits (IC), LEDs, discrete devices, advanced packaging (TSV, RDL, Bumping), and MEMS. The company operates production lines with stated capacities of 500 tons/year for G/I-line positive photoresist, 100 tons/year for 248nm photoresist, and 1,000 tons/year for supporting reagents, all concentrated at a single headquarters site in Beijing's Tianzhu Comprehensive Bonded Zone, Shunyi District.

Kempur's business model is direct enterprise B2B sales to semiconductor fabs with deep technical collaboration on product qualification and validation. Customers include most of China's leading chipmakers — SMIC, Shanghai Hualong Microelectronics, Yangtze Memory, Hua Hong Group, Huarun Microelectronics — as well as LED manufacturers such as San'an Optoelectronics and HC SemiTek. Seven KrF products are reportedly in mass production at customer fabs and five additional products are in customer validation, including for Contact/Hole and Metal layer applications at 0.13μm and below. The company's R&D infrastructure includes two mini FAB facilities equipped with ASML PAS5500/850 scanning exposure machines (0.11μm resolution), Nikon steppers, TEL ACT8 coating/development tracks, and Hitachi S9220 CD SEM for formulation development and product evaluation. Quality and safety frameworks include ISO 9001 (since 2006), ISO 14001, ISO 45001, and IECQ QC080000 hazardous-substance management certification (since 2013).

Since 2020, Kempur has been a controlled subsidiary of Tongcheng New Materials (彤程新材, Shanghai Stock Exchange: 603650), which acquired a majority stake through Tongcheng Electronics, directly holding 56.56% of equity and over 70% of voting rights. In November 2021, Kempur announced a strategic cooperation with DuPont at the China International Import Expo to provide high-performance photoresist materials to Chinese IC chip manufacturers, leveraging DuPont's global semiconductor materials portfolio alongside Kempur's local market access and customer relationships. Revenue figures are not publicly disclosed.

Direct peers

• JSR Corporation: Japan-based global leader in photoresists (ArF immersion, EUV, KrF, I/G-line) and semiconductor materials. Most directly comparable to Kempur across the same resist chemistry family and IC customer base, but with substantially broader technology depth.
• Tokyo Ohka Kogyo (TOK): One of the 'Big Four' global photoresist manufacturers, with deep coverage in KrF, ArF and EUV resists for logic and memory fabs. Directly comparable product overlap to Kempur's KrF and I/G-line portfolio.
• Shin-Etsu Chemical: Major Japanese photoresist and silicon wafer producer, with leading positions in KrF, ArF and EUV materials. Comparable because it sells into the same fab customer base and offers overlapping lithography chemistry.
• DuPont Electronics & Industrial: Global photoresist and electronic materials supplier; signed a 2021 strategic cooperation with Kempur to serve Chinese IC customers. Direct competitor in KrF/I-line and specialtys, and Kempur's named strategic partner.
• Merck KGaA (Performance Materials / AZ Electronic Materials): Supplies photoresists and patterning materials to global semiconductor fabs through its AZ Electronic Materials franchise. Overlaps with Kempur in KrF, I/G-line and specialty resists for logic and memory manufacturing.
• Fujifilm Electronic Materials: Subsidiary of Fujifilm producing photoresists, chemicals and packaging materials for semiconductor and display customers. Comparable product set in KrF and I/G-line resists serving Asian fabs.

Broad incumbents

• Sumitomo Chemical: Diversified Japanese chemicals group with a semiconductor materials segment including photoresists (notably EUV). A broader incumbent that overlaps with Kempur in IC patterning chemistry but competes primarily through ArF/EUV rather than KrF.

Emerging players

• Resonac (formerly Showa Denko): Japanese materials supplier expanding into EUV and advanced patterning chemistry. Partial overlap with Kempur in advanced lithography R&D trajectories, though primarily serving global rather than Chinese fabs.

Regional players

• Shanghai Sinyang Semiconductor Materials: Chinese producer of photoresists and wet chemicals used in semiconductor and display manufacturing. A domestic regional peer competing with Kempur primarily inside China on I/G-line and supporting reagents.
• Anji Microelectronics Technology (安集科技): Chinese semiconductor materials company specializing in CMP polishing slurries and functional wet chemicals, listed on the STAR Market. Comparable as a domestic Chinese semiconductor materials supplier targeting the same fab customers, though in adjacent chemistry rather than photoresists.
