A device is disclosed. The device includes a carrier substrate having first and second major surfaces. The first surface includes a die region and contact pads and the second surface includes package contacts. The carrier substrate includes a patterned lead frame which defines a line level with conductive traces and a via level with via contacts. The patterned lead frame provides interconnections between the contact pads and package contacts. The carrier substrate further includes a dielectric layer isolating the conductive traces and via contacts. The device includes a die mounted on the die region of the first surface.

Semiconductor packages and methods of packaging semiconductor devices

Semiconductor packages and methods of forming a semiconductor package are disclosed. The method includes providing at least one die having first and second surfaces. The second surface of the die includes a plurality of conductive pads. A permanent carrier is provided and the at least one die is attached to the permanent carrier. The first surface of the at least one die is facing the permanent carrier. A cap having first and second surfaces is formed to encapsulate the at least one die. The first surface of the cap contacts the permanent carrier and the second surface of the cap is disposed at a different plane than the second surface of the die.

Semiconductor packages and methods of forming a semiconductor package are disclosed. The method includes providing at least one die having first and second surfaces. The second surface of the die includes a plurality of conductive pads. A support carrier is provided and the at least one die is attached to the support carrier.
