Circuit board with embedded passive component and manufacturing method thereof

摘要

The present disclosure relates to a semiconductor device substrate and a method for making the same. The semiconductor device substrate includes a first dielectric layer, a second dielectric layer and an electronic component. The first dielectric layer includes a body portion, and a wall portion protruded from a first surface of the body portion. The wall portion has an end. The second dielectric layer has a first surface and an opposing second surface. The first surface of the second dielectric layer is adjacent to the first surface of the body portion. The second dielectric layer surrounds the wall portion. The end of the wall portion extends beyond the second surface of the second dielectric layer. The electronic component includes a first electrical contact and a second electrical contact. At least a part of the electronic component is surrounded by the wall portion.
