CUSTOMERS
Founded in 2008, HGD is a nationally recognized high-tech enterprise with over 17 plus years of focused development in advanced ceramic materials. The company has built a global footprint, serving customers across four continents in the semiconductor, energy, and communications industries.
HGD’s R&D team has overcome critical technical barriers in ceramic material performance — including thermal conductivity uniformity in AlN systems, high-resistivity control for Coulomb-type ESC applications, and structural reliability in high-stress Si₃N₄ components.
Every product is engineered to meet application-specific performance targets. HGD’s full-spectrum capability — from material formulation to final inspection — means customers work with a single, accountable partner from specification to qualification.
