Abstract: A method includes forming a metallic feature, forming an etch stop layer over the metallic feature, implanting the metallic feature with a dopant, forming a dielectric layer over the etch stop layer, performing a first etching process to etch the dielectric layer and the etch stop layer to form a first opening, performing a second etching process to etch the metallic feature and to form a second opening in the metallic feature, wherein the second opening is joined with the first opening, and filling the first opening and the second opening with a metallic material to form a contact plug.

Abstract: The present disclosure provides a semiconductor package structure. The semiconductor package structure includes a substrate, a first electronic component and a support component. The first electronic component is disposed on the substrate. The first electronic component has a backside surface facing a first surface of the substrate. The support component is disposed between the backside surface of the first electronic component and the first surface of the substrate. The backside surface of the first electronic component has a first portion connected to the support component and a second portion exposed from the support component.

Abstract: The tool connector includes a socket having a receiving space and a through hole communicating the receiving space, a sliding member slidably received in the receiving space, a positioning member received in the receiving space, and a hook member. A funnel-shaped opening is formed at an end of the receiving space. The sliding member is connected to the socket with an end via a first elastic member, and the other end is for a tool bit to abut against. The positioning member is selectively inserted into the through hole. An end of the hook member is connected to the sliding member, and the other end has a hook portion for grasp the tool bit. When the positioning member is moved inward and the sliding member is moved toward the funnel-shaped opening, the hook portion is swingable in the funnel-shaped opening to release the tool bit.
