The method includes forming a low-k dielectric layer; form an opening in the low-k dielectric layer; forming a barrier layer covering a bottom and sidewalls of the low-k dielectric layer; performing a treatment to the barrier layer in an environment comprising a treatment gas; and filling the opening with a conductive material, wherein the conductive material is on the barrier layer.
Abstract:
A durable golf tee construction to prevent the loss of or damage to golf tees, allowing golf players to play many rounds of golf using only one golf tee. Breakable but connected tee prevents the tee to be damaged upon striking; a string connected two tees allowing the easy location of tee, and thus preventing loss of tee.
Abstract:
A semiconductor device having a nonconductive cap layer comprising a first metal element. The nonconductive cap layer comprises a first metal nitride, a first metal oxide, or a first metal oxynitride over conductive lines and an insulating material between the conductive lines. An interface region may be formed over the top surface of the conductive lines, the interface region including the metal element of the cap layer. The cap layer prevents the conductive material in the conductive lines from migrating or diffusing into adjacent subsequently formed insulating material layers. The cap layer may also function as an etch stop layer.

Abstract:
A signal transmission module is provided. The signal transmission module includes an electrical connector, a linked unit, a data connector, a sliding block, a link and a lock block. The data connector rotates and expands according to a first shaft and a first elastomer of the linked unit, and electrically connects to the electrical connector. During retraction of the data connector, the data connector pushes the sliding block. Then the sliding block moves against the lock block so that the lock block rotates. The lock block rotates to lock and secure the data connector by the lock piece, while a cam of the link moves to a secure location along an incline plane of a track of the sliding block.
Abstract:
The present invention is directed to a waterproof electronic device with a test structure, including a test opening, a sealing structure and a fixation structure. The test opening is arranged on a housing of the waterproof electronic device, and is used for injecting a test fluid for detecting water leak. The sealing structure is arranged on the housing or a test fixture, and is used for holding a sealing element such that the waterproof electronic device and the test fixture may be sealed to each other when performing a leak test. The fixation structure is used for fixing the test fixture on the waterproof electronic device.
Abstract:
A composite barrier layer provides superior barrier qualities and superior adhesion properties to both dielectric materials and conductive materials as the composite barrier layer extends throughout the semiconductor device. The composite barrier layer may be formed in regions where it is disposed between two conductive layers and in regions where it is disposed between a conductive layer and a dielectric material. The composite barrier layer may consist of various pluralities of layers and the arrangement of layers that form the composite barrier layer may differ as the barrier layer extends throughout different sections of the device. Amorphous layers of the composite barrier layer are generally disposed to form boundaries with dielectric materials and crystalline layers are generally disposed to form boundaries with conductive materials such as interconnect materials.

An opening in a dielectric layer having a unique barrier layer structure is provided. In an embodiment, the opening is a via and a trench. The barrier layer, which may comprise one or more barrier layers, is formed such that the ratio of the thickness of the barrier layers along a sidewall approximately midway between the bottom of the trench and the top of the dielectric layer to the thickness of the barrier layers along the bottom of the trench is greater than about 0.55. In another embodiment, the ratio of the thickness of the barrier layers along a sidewall approximately midway between the bottom of the trench and the top of the dielectric layer to the thickness of the barrier layers along the bottom of the via is greater than about 1.0. An underlying conductive layer may be recessed.
