EMBEDDED TOROIDAL TRANSFORMERS IN CERAMIC SUBSTRATES

摘要

Method for forming a transformer ( 118 ) in a ceramic substrate. The method can include the steps of forming at least one conductive coil ( 119 a , 119 b) comprising a plurality of turns about an unfired ceramic toroidal core region ( 120 a , 120 b) defined within an unfired ceramic substrate ( 100 ). The method can also include the step of co-firing the unfired ceramic toroidal core region ( 120 a , 120 b), the unfired ceramic substrate ( 100 ), and the conductive coil ( 119 a , 119 b) to form an integral ceramic substrate structure with the conductive coil at least partially embedded therein.
