A semiconductor device package includes a first conductive base, a first insulation layer and a second insulation layer. The first conductive base has a first surface, a second surface opposite to the first surface and a lateral surface extended between the first surface and the second surface. The lateral surface includes a first portion adjacent to the first surface and a second portion adjacent to the second surface. The first insulation layer comprises a first insulation material. The first insulation layer has a first surface and a second surface opposite to the first surface. The first insulation layer covers the first portion of the lateral surface of the first conductive base. The second insulation layer comprises a second insulation material and covers the second portion of the lateral surface of the first conductive base. The first insulation material is different from the second insulation material.
