Claim 4:
5. An electronic device, comprising:
a substrate including:
a first face and a second face opposite to the first face; and
a first sidewall and a second sidewall transverse to the first sidewall, the first and second sidewalls extend from the first face to the second face;

a first wedging element made of a mask resin layer on the second face and including a first insulated portion extending outward from the second face, the first wedging element including:
a first end and a second end spaced apart from the first end in a first direction;
a first dimension extending from the first end to the second end in the first direction;
a third end and a fourth end spaced apart from the third end in a second direction transverse to the first direction; and
a second dimension extending from the third end to the fourth end in the second direction, the second dimension is greater than the first dimension;

a second wedging element on the second face made of a mask resin layer and including a second insulated portion extending outward from the second face, the second wedging element including:
a fifth end and a sixth end spaced apart from the fifth end in the second direction;
a third dimension extending from the fifth end to the sixth end in the second direction;
a seventh end and an eighth end spaced apart from the seventh end in the first direction; and
a fourth dimension extending from the seventh end to the eighth end in the first direction, the fourth dimension being less than the third dimension;

a die in contact with a first surface of the first insulated portion of the first wedging element spaced apart from the second face and in contact with a second surface of the second insulated portion spaced apart from the second face; and
an adhesive coupling the die to the second face of the substrate.
