10 Ways These Two Brothers Hit the Billionaire Ranks Fueling China’s Tech Boom
When people talk about China’s tech boom, the focus usually lands on chipmakers and big-name technology companies. But some of the biggest winners have come from behind the scenes. Brothers Zhu Shuangquan and Zhu Shunquan built Hubei Dinglong into an important supplier as China worked to rely less on foreign technology. The company’s growth has made both brothers billionaires and shows how fortunes are being built throughout the broader tech supply chain.

The Zhu brothers did not take the usual route into the semiconductor industry. Instead of focusing on chips themselves, they built a business around the materials used to make them. Hubei Dinglong became a major supplier of chemical-mechanical polishing products that help create smooth silicon wafer surfaces. It is highly specialized work that rarely makes headlines, but it plays a critical role in the chipmaking process.

China’s effort to strengthen domestic semiconductor production increased demand for local suppliers capable of replacing imports. Dinglong positioned itself at the center of that trend. As chip manufacturers searched for Chinese alternatives, the company already had products ready for commercial use.
Their Expansion Went Beyond One Product Line

The company moved into polishing slurries, cleaning fluids, photoresists, and packaging materials. That broad lineup reduced dependence on any single market segment. It also made Dinglong more useful to customers looking for suppliers capable of serving multiple stages of the manufacturing process.

The business originally focused on chemicals used in printer toners and other printing supplies. After building expertise in specialty chemicals, management spotted similarities between toner materials and semiconductor polishing materials. That observation led to a major strategic shift.
A Public Listing Opened New Doors

Going public gave the company more than visibility. Dinglong raised 458 million yuan through its 2010 listing on Shenzhen’s ChiNext market. Access to capital allowed the business to fund research projects that often require years before producing meaningful revenue. Public-market funding helped provide the resources needed to compete against larger international rivals.
They Chose Patience Over Quick Wins

Products often spend years undergoing testing before customers approve them for production use. The company accepted that timeline and continued investing. Recent financial results suggest the patience paid off. New business segments such as photoresists and advanced packaging materials are still developing, yet have already entered commercial supply chains.
Advanced Packaging Became A Smart Bet

As chips become more powerful, packaging technology has grown increasingly important. Dinglong entered this segment by developing temporary bonding adhesives used during wafer thinning and stacking processes. These materials play a role in creating advanced memory products and other high-performance components.
Domestic Revenue Provided A Strong Foundation

About 70 percent of Dinglong’s revenue has come from customers inside China. That concentration proved helpful during a period when many Chinese technology companies prioritized local supply chains. A large domestic market gave the company room to scale products before seeking broader opportunities.
Their Backgrounds Prepared Them For The Challenge

Before launching Dinglong in 2000, both brothers worked in state-owned enterprises involved in international trade and economic cooperation. Those roles exposed them to manufacturing, imports, and business operations. The experience likely shaped their understanding of where China relied heavily on foreign suppliers.
Investors Rewarded Years Of Preparation

The billionaire status of the Zhu brothers did not appear overnight. Shares of Hubei Dinglong more than doubled within a year as investors gained confidence in its semiconductor business. Market value often reflects expectations about the future rather than the past. In Dinglong’s case, investors appear to believe the company still has room to expand alongside China’s technology ambitions.
