Abstract

In this paper, we review three material options for embedded capacitors: thin FR4 epoxy-glass laminate, adhesiveless copper on polyimide substrate, and unsupported epoxy filled with high dielectric constant ceramic powder. Characteristics including material components and construction, dielectric constant and loss, and topography at metal-dielectric interfaces are compared. Attention is given to frequency dependence of the different material properties. Effects of the material characteristics on electrical performance, including capacitance and power and ground plane impedance, are examined. Finally, processing and fabrication issues are discussed.
