Electrostatic chucks (ESCs) are critical components in semiconductor and display manufacturing, providing contact handling of delicate substrates. However, optimizing their performance requires precise control of material properties and structural design, particularly the dielectric layer and ESC body. In this study, we fabricated ESCs using a dual-material design, in which the dielectric layers were printed from BaTiO3-resin inks, while the bodies were printed using Al2O3-resin ink via digital light-processing (DLP) three-dimensional printing. The rheological properties of both Al2O3- and BaTiO3-resin inks were systematically characterized to determine their suitability for DLP printing, and the dielectric properties of the corresponding cured composites were evaluated to guide ESC performance optimization. ESC bodies and dielectric layers could be printed using Al2O3-resin ink reliably. The ESC body exhibited high breakdown strength, whereas the dielectric layers exhibited high dielectric constants. The fabricated ESCs exhibited excellent structural fidelity and enabled the reliable integration of internal electrodes via liquid-metal injection. Finite element analysis simulations indicated that the dielectric constant primarily governed the chucking force and was highly localized near the edges of the embedded electrodes. Experimental results confirmed that ESCs with BaTiO3-based dielectrics consistently outperformed those with Al2O3-based dielectrics. This finding is consistent with the simulation results. Overall, the combination of material selection, additive manufacturing, and electrostatic modeling provides a comprehensive and robust strategy for developing next-generation ESCs with tunable performance and complex geometries. These ESCs are suitable for advanced precision handling in the semiconductor and display industries.
