Abstract
A semiconductor substrate is provided, including a substrate body, a plurality of conductive through holes penetrating the substrate body, and at least one pillar disposed in the substrate body with the at least one pillar being free from penetrating the substrate body. When the semiconductor substrate is heated, the at least one pillar adjusts the expansion of upper and lower sides of the substrate body. Therefore, the upper and lower sides of the substrate body have substantially the same thermal deformation, and the substrate body is prevented from warpage.
