BaTiO 3 –resin hybrid composite is one of the most promising candidates for the embedded capacitors. We utilized the inkjet printing to prepare BaTiO 3 –resin hybrid film. In order to extract the maximum relative permittivity from the hybrid films, the following aspects were investigated: (1) the effect of BaTiO 3 powder size on the relative permittivity of inkjet‐printed films and (2) the improvement of the packing density by using two different sizes of BaTiO 3 powders resulting in the increase in relative permittivity. The microstructures of the films were investigated to confirm the improvement on the packing density and their effects on the relative permittivity.
