This invention relates in general to capacitors including one or more layers of dielectric material wherein at least one of the layers including a multiaxially oriented lyotropic liquid crystalline polymer (LCP) film. The present invention also provides lyotropic LCPs films having less than 0.5% residual ionic contaminants and a method of preparing such films and capacitors including such films. In preferred embodiments, the invention further provides a capacitor wherein the liquid crystalline polymer film has less than 0.5% residual ionic contaminants.

Liquid crystalline polymer capacitors

The invention is for the formation of multilayer circuit boards where layers are formed sequentially using selective plating techniques and imaging of dielectric materials to achieve fine line resolution and interconnections between circuits. The invention permits the sequential formation of multilayers of higher density using imaging techniques. The method may also be used in single-sided and double-sided circuit board fabrication and for inner layers used in multilayer circuit boards.
