摘要:
A method for manufacturing a metal plug is described. A substrate with an opening is provided. Then, a barrier layer is formed on a surface of the opening. Thereafter, a metallic layer is formed over the substrate so that the opening is also filled. Next, a planarization process is performed to remove the metallic layer outside the opening. One main feature of the present invention is the performance of at least a high temperature treatment after the metallic layer is formed. Due to the high temperature treatment, internal stress between different layers is released.

A method of forming a plug is provided. First, a substrate comprising at least a dielectric layer is provided, and a patterned hard mask is formed on the dielectric layer to define a position of at least a plug hole. Subsequently, the dielectric layer is etched for forming the plug hole. A barrier layer and a conductive layer are formed on the substrate, and the plug hole is filled by the conductive layer. Thereafter, first, second, and third chemical mechanical polishing processes are performed in turn. Finally, a fourth chemical mechanical polishing process is performed to remove portions of the conductive layer.

A method of forming a semiconductor structure having a metal gate. Firstly, a semiconductor substrate is provided. Subsequently, at least a gate structure is formed on the semiconductor substrate. Afterwards, a spacer structure is formed to surround the gate structure. Then, an interlayer dielectric is formed. Afterwards, a planarization process is performed for the interlayer dielectric. Then, a portion of the sacrificial layer is removed to form an initial etching depth, such that an opening is formed to expose a portion of the spacer structure. The portion of the spacer structure exposed to the opening is removed so as to broaden the opening. Afterwards, remove the sacrificial layer completely via the opening. Finally, a gate conductive layer is formed to fill the opening.

Techniques are described for facilitating transactions involving items and users in various ways. In some situations, item transactions are coordinated by an automated Item Transaction (or “IT”) system provided via one or more computing systems, such that users of the IT system who have available items are matched with other users of the IT system who desire those items. The types of items being involved in transactions via the IT system may vary, and in some situations may include items such as music CDs, video DVDs, computer games, computer software, etc. The operation of the IT system may be enhanced in various ways, including by selecting appropriate users to receive opportunities to sell items available from those users, such as in a manner to balance supply and demand for items, and by notifying the selected users of those opportunities.

In a method of the present invention during a salicide process, before a second thermal process, a dopant is implanted at a place located in a region ranging from a NixSi layer at meddle height down to a front thereof, or before formation of the NixSi layer, located in a region ranging from a silicon layer at a depth ranging from a half of a predetermined thickness of a NiSi layer down to a depth where is a predetermined front of the NiSi layer. The dopant is allowed to be heated with the NixSi layer together during the second thermal process to form a Si/NiSi2/NiSi interface which may reduce SBH and improve series resistance to obtain a semiconductor device having an excellent performance.
