Hubei Dinglong’s Growth Accelerated by china’s Semiconductor Independence Strategy
China’s persistent push to establish self-sufficiency in semiconductor manufacturing has opened significant avenues for industry players.Among the prominent beneficiaries is Hubei Dinglong, a vital provider of essential materials used in chip fabrication. Over the last twelve months, its Shenzhen-listed shares have surged nearly 116%, propelling cofounders Zhu Shuangquan and Zhu Shunquan into billionaire ranks.
The Founding Brothers Steering a Semiconductor Materials Leader
Zhu Shuangquan, 61, who serves as chairman, and his younger brother Zhu Shunquan, 57 and CEO of the company, each control close to 15% equity. with recent share prices closing at 64.19 yuan apiece, their net worth is estimated at approximately $1.3 billion each. The Wuhan-based enterprise has not publicly commented on these valuations.
Expertise in Chemical Mechanical Polishing: A Strategic Advantage
Dinglong holds a crucial position within China’s semiconductor supply chain through its mastery of chemical mechanical polishing (CMP). This process refines silicon wafer surfaces to enable ultra-precise circuit patterning and chip stacking-an indispensable step for producing advanced microchips. Notably, Dinglong stands out as the sole Chinese company offering a thorough range of CMP materials domestically-including both polishing slurries that smooth wafers and cleaning agents that eliminate residues after processing.
Broadening Horizons with Lithography Materials Amid Export Controls
In response to U.S.-imposed export restrictions targeting china’s chip sector since 2022, Dinglong expanded its portfolio to include lithography chemicals-a critical bottleneck for achieving domestic semiconductor autonomy. The firm produces photoresist compounds that capture intricate circuit designs during ultraviolet exposure; however, these products currently serve only lower-tier chip manufacturing processes.
Diversification into Cutting-Edge Packaging Adhesives
The company has also ventured into specialized adhesives essential for modern semiconductor packaging technologies. As an example, temporary bonding adhesives secure silicon wafers onto glass carriers so they can be thinned below human hair thickness before stacking-an critically important technique used in high-bandwidth memory chips powering today’s data centers worldwide.
Robust Financial results Reflect Growing Market Demand
During Q1 2026 alone, Dinglong posted an remarkable net profit increase of 78% year-over-year reaching 251 million yuan ($36.9 million), alongside revenue growth of 24% totaling one billion yuan-primarily fueled by CMP material sales. Although production volumes remain modest for advanced packaging supplies and photoresists at this stage, output levels have stabilized steadily.
A detailed breakdown from early 2026 remains unavailable; however last year over half of Dinglong’s total revenue exceeding 3.7 billion yuan originated from semiconductor-related segments such as CMP chemicals, lithography substances, and packaging materials. Additionally notable is their role supplying OLED display components while gradually divesting printer-related businesses like toner manufacturing to sharpen focus on semiconductors-with roughly seventy percent of sales generated domestically within china.
A Legacy Rooted in Reducing Import Reliance
the brothers’ professional journeys began with managerial roles at state-owned foreign trade enterprises before founding Dinglong about twenty years ago with ambitions centered on decreasing China’s dependence on imported technology inputs.
Their initial market entry focused on chemical products primarily used as printer toners-a sector then dominated by Japanese and Western multinational corporations-and later expanded across various printing consumables becoming one of China’s leading suppliers for color printing chemicals.
Pioneering Transition Toward Semiconductor Material Production
Dinglong went public via Shenzhen’s ChiNext board tech IPO raising approximately 458 million yuan back in 2010; two years later they strategically shifted toward developing CMP materials aiming to challenge foreign incumbents’ dominance much like their earlier success disrupting printer chemical markets.This pivot was inspired when team members identified overlapping chemical properties between toner formulations and CMP slurries enabling smoother R&D adaptation efforts.
Nurturing Entrepreneurial Resolve Through Challenges
“At our inception,” reflected Zhu Shuangquan about those early days,”beyond ideas or market insights Chinese private firms had little else but sheer determination-a ‘burn the boats’ mentality propelling us forward relentlessly.” He emphasized this relentless ambition remains core today as they pursue new frontiers globally.”
A Reflection of China’s Broader Technological Sovereignty Ambitions
Dinglong exemplifies how targeted innovation combined with strategic diversification empowers Chinese companies not only to thrive amid geopolitical headwinds but also contribute considerably toward national objectives surrounding technological sovereignty-especially within semiconductors where global competition intensifies annually alongside rising demand projected beyond $600 billion worldwide by mid-decade according to industry forecasts.
