1. A compound metal lid for a semiconductor chip package, comprising:
a first cover including a first frame body, a plurality of riveting holes, and an upper opening, wherein the riveting holes penetrate through the first frame body and are symmetrically distributed on the first frame body, the upper opening is formed at an inner part of the first frame body, and the riveting holes surround the upper opening; and
a second cover including a second frame body, a plurality of riveting protrusions, and a lower opening, wherein the plurality of the riveting protrusions are distributed on an upper surface of the second frame body, and the lower opening penetrates through an inner part of the second frame body;
wherein the first frame body of the first cover is disposed on the upper surface of the second frame body, and the plurality of the riveting protrusions are correspondingly riveted in the plurality of the riveting holes;
wherein each of the riveting holes has an upper half-hole and a lower half-hole spatially connected to the upper half-hole, the upper half-hole has a diameter identical throughout the upper half-hole, the lower half-hole tapers downward from the upper half-hole, each of the riveting protrusions is shaped as a cylinder and has a diameter identical throughout the riveting protrusion, and a diameter of each of the riveting protrusions is smaller than or equal to a minimum diameter of any of the lower half-holes.
