Abstract
A filter can include a monolithic substrate and at least one conductive layer formed over a top surface of the monolithic substrate and along at least a portion of one or more of a first top edge of the monolithic substrate or a second top edge of the monolithic substrate. A cover layer can be arranged over the top surface of the monolithic substrate. A shield layer can connect with one or more of the conductive layer(s) at the first top edge or the second top edge of the monolithic substrate. The shield layer can include a first portion formed over the first side surface of the cover layer, a second portion formed over the top surface of the cover layer, and a third portion formed over the second side surface of the cover layer.
Claims17
A filter comprising:
- a monolithic substrate having a top surface, a first side surface perpendicular to the top surface, a second side surface perpendicular to the top surface, a first top edge along an intersection between the top surface and the first side surface, and a second top edge opposite the first top edge and along an intersection between the top surface and the second side surface;
- at least one conductive layer formed over the top surface of the monolithic substrate and along at least a portion of one or more of the first top edge of the monolithic substrate or the second top edge of the monolithic substrate;
- a cover layer arranged over the top surface of the monolithic substrate, the cover layer having a top surface parallel with the top surface of the monolithic substrate, the cover layer having a first side surface and a second side surface opposite the first side surface, and wherein the first side surface of the cover layer is parallel with the first side surface of the monolithic substrate, and the second side surface of the cover layer is parallel with the second side surface of the monolithic substrate;
- and
- a shield layer that connects with one or more of the at least one conductive layer at one or more of the first top edge or the second top edge of the monolithic substrate, and wherein the shield layer comprises a first portion formed over the first side surface of the cover layer, a second portion formed over the top surface of the cover layer, and a third portion formed over the second side surface of the cover layer.
A method of forming a filter, the method comprising:
- providing a monolithic substrate having a top surface, a first side surface perpendicular to the top surface, a second side surface perpendicular to the top surface, a first top edge along an intersection between the top surface and the first side surface, and a second top edge opposite the first top edge and along an intersection between the top surface and the second side surface;
- forming at least one conductive layer over the top surface of the monolithic substrate and along at least a portion of one or more of the first top edge of the monolithic substrate or the second top edge of the monolithic substrate;
- arranging a cover layer over the top surface of the monolithic substrate, the cover layer having a top surface parallel with the top surface of the monolithic substrate, the cover layer having a first side surface and a second side surface opposite the first side surface, and wherein the first side surface of the cover layer is parallel with the first side surface of the monolithic substrate, and the second side surface of the cover layer is parallel with the second side surface of the monolithic substrate;
- and
- forming a shield layer that connects with one or more of the at least one conductive layer at one or more of the first top edge or the second top edge of the monolithic substrate, and wherein the shield layer comprises a first portion formed over the first side surface of the cover layer, a second portion formed over the top surface of the cover layer, and a third portion formed over the second side surface of the cover layer.
