Abstract
An antenna device includes a first substrate, a second substrate, an antenna layer, and a redistribution layer. The first substrate has a first surface, a second surface opposite to the first surface, and an inclined sidewall adjoining the first and second surfaces. The second substrate is below the first substrate. The first surface of the first substrate faces toward the second substrate. The antenna layer is located on the first surface of the first substrate. The redistribution layer extends from the second surface of the first substrate to the second substrate along the inclined sidewall of the first substrate, and the redistribution layer has a first section in contact with an end of the antenna layer.
Claims18
An antenna device, comprising:
- a first substrate having a first surface, a second surface opposite to the first surface, and an inclined sidewall adjoining the first and second surfaces;
- a second substrate below the first substrate, wherein the first surface of the first substrate faces toward the second substrate;
- an antenna layer located on the first surface of the first substrate;
- and
- a redistribution layer extending from the second surface of the first substrate to the second substrate along the inclined sidewall of the first substrate, wherein the redistribution layer has a first section in contact with an end of the antenna layer.
A manufacturing method of an antenna device, comprising:
- forming an antenna layer on a first surface of a first substrate, wherein the first substrate has a first surface and a second surface opposite to the first surface;
- bonding a second substrate to the first substrate, wherein the first surface of the first substrate faces toward the second substrate;
- removing an edge portion of the first substrate to form a groove such that an end of the antenna layer is exposed, wherein the first substrate forms an inclined sidewall adjoining the first and second surfaces;
- and
- forming a redistribution layer extending from the second surface of the first substrate to the second substrate along the inclined sidewall, wherein the redistribution layer has a first section in contact with the end of the antenna layer.
