Abstract: The present disclosure describes a method for forming liner-free or barrier-free conductive structures. The method includes depositing an etch stop layer on a cobalt contact disposed on a substrate, depositing a dielectric on the etch stop layer, etching the dielectric and the etch stop layer to form an opening that exposes a top surface of the cobalt contact, and etching the exposed top surface of the cobalt contact to form a recess in the cobalt contact extending laterally under the etch stop layer. The method further includes depositing a ruthenium metal to substantially fill the recess and the opening, and annealing the ruthenium metal to form an oxide layer between the ruthenium metal and the dielectric.

Abstract: An electrical connector with extension terminals includes an insulating housing, a movable terminal, a spring and a conductive reed terminal. The insulating housing has terminal axial holes each having a ridge. The insulating housing has reed sockets arranged around and communicated with the terminal axial holes. The movable terminal accommodates therein a spring. The movable terminal has a groove. The movable terminal is such inserted into the terminal axial hole of the insulating housing that the groove fittingly receives the ridge, thereby limiting the movable terminal to move in the terminal axial hole but preventing the movable terminal from leaving from and rotating in the terminal axial hole. The conductive reed terminal has inserts and a weld leg. The insert has a reed. When the insert is inserted into the reed socket, the reed abuts against the movable terminal, thereby establishing conductivity therebetween.

Abstract: An LED lamp holder includes a frame ring that has slits for fittingly receiving retaining portions of some inserts; the inserts, each including the retaining portion, a top piece that has a hook, a positioning hole and a bore, and a bottom piece that has a hook and a bore, wherein the hooks of one insert are to be combined with the bores another insert, so that all the inserts are connected as a series; and a locking seat that has notches for receiving the retaining portions of the inserts, and has pins corresponding to the positioning holes of the inserts. After the pins are inserted into the positioning holes of the inserts, stamping is performed on the pins to fix the frame ring, the inserts and the locking seat as an unity, so as to form the LED lamp holder.

Abstract: A connector locking base structure of an LED lamp includes a connector locking base having a conventional lamp connector and a locking base coupled together such that a threaded end of a cap of the LED lamp can be screwed to the locking base of the connector locking base. The conventional lamp connector of the connector locking base can be inserted into a socket for use with a conventional lamp, thereby allowing power to be supplied to the LED lamp for emission of light. Grooves formed in a casing of the conventional lamp connector are engaged with hooks of the locking base. A screw hole is centrally formed in the locking base. The hooks are provided on the inner side of the locking base and engaged with the grooves of the conventional lamp connector, respectively, to thereby form the connector locking base.
