    Abstract: A method of forming a buried resistor within a cavity for use in electronic packages using two glass impregnated dielectric layers, one with a clearance hole, the second with a resistor core, the clearance hole being placed over the resistor core and the assembly fusion bonded. The space remaining around the resistor core is filled with a soldermask material and the assembly is coated with metal. Thru-holes are drilled, cleaned, and plated and then the metal coating is etched and partially removed. The soldermask is then removed and a layer of gold plating is applied to the exposed metal surfaces. The use of glass impregnated dielectric layers and fusion bonding eliminates the fluorinated ethylene propylene resin (FEP) bleed problem associated with previous buried resistor cavity assemblies.

    Abstract: Via holes are formed in an electrically conductive power plane. Photo-imageable dielectric (PID) material is applied to one side of the power plane filling the via holes. The power plane side with no PID material is exposed to light energy to cure the PID material in the via holes. A developer is used to remove any uncured PID material. Signal plane assemblies comprising a conductive signal plane and a dielectric layer are laminated onto the filled power plane forming a two signal and one power plane (2S1P) structure. In another embodiment, the power plane has PID material applied from both sides. A photo-mask is applied to the power plane and the PID material in the via holes is cured with light energy. A developer is used to remove uncured PID material. Signal plane assemblies, as described above, are laminated onto the filled power plane forming a 2S1P structure.
