Abstract:
A method for fabricating strained silicon transistors is disclosed. First, a semiconductor substrate is provided, in which the semiconductor substrate includes a gate, at least a spacer, and a source/drain region formed thereon. Next, a precursor, silane, and ammonia are injected, in which the precursor is reacted with silane and ammonia to form a high compressive stress film on the surface of the gate, the spacer, and the source/drain region. Preferably, the high compressive stress film can be utilized in the fabrication of a poly stressor, a contact etch stop layer, and dual contact etch stop layers.

A method of forming a contact is provided. A substrate having at least two conductive devices is provided. A spacing is located between the two conductive devices. A first dielectric layer is formed over the substrate to cover the two conductive devices and the spacing. A seam is formed in the first dielectric layer within the spacing. Then, a portion of the first dielectric layer is removed to form an opening so that the width of the seam is expanded. A second dielectric layer is formed over the first dielectric layer to fill the opening. A portion of the second dielectric layer and a portion of the first dielectric layer within the spacing are removed until a portion of the surface of the substrate is exposed and a contact opening is formed in the location for forming the contact. Finally, conductive material is deposited to fill the contact opening.
Abstract:
A barrier layer structure includes a first dielectric layer forming on a conductive layer and having a via being formed in the first dielectric layer, wherein the via in the first dielectric layer is connected to the conductive layer. A first metal layer is steppedly covered on the first dielectric layer. A layer of metallized materials is steppedly covered on the first metal layer, but the layer of metallized materials does not cover the first metal layer above the via bottom connected to the conductive layer in the dielectric layer. A second metal layer is steppedly covered on the layer of metallized materials, and the second metal layer is covered the first metal layer above the via bottom connected to the conductive layer in the dielectric layer. The barrier layer structure will have lower resistivity in the bottom via of the first dielectric layer and it is capable of preventing copper atoms from diffusing into the dielectric layer.

Abstract:
A method of forming silicide is described. A layer of refractory metal is deposited on a substrate, and then a first annealing process is performed to form silicide, followed by removal of unreacted metal. Next, a species implanting process is carried out to implant species of neutral atoms into the silicide to break up lattice structure of the silicide, so that the problem of junction leakage induced by spiking and piping diffusion under high temperature during a subsequent second annealing process is avoided.

The mail agent assesses the flag, and performs a predefined process including storing mail content of the email message in a database, generating a new email message comprising a link to the mail content of the email message in the database, and forwarding the new email message to recipients of the email message if the flag is a predefined value.
Abstract:
A method of problem case packaging handling consists collecting manufacturing problem information from entities associated with fabrication of a semiconductor product; and distributing the manufacturing problem information into problem cases which are stored in a problem database, each problem case representing a respective manufacturing problem and being associated with manufacturing problem information related to that problem case.
Abstract:
A process of metal interconnects and a structure of metal interconnect produced therefrom are provided. An opening is formed in a dielectric layer. A metal layer is formed over the dielectric layer filling the opening. A film layer is formed on the metal layer and the dielectric layer. The film layer is reacted with the metal layer during a thermal process, and a protective layer is formed on the surface of the metal layer. The portion of the film layer not reacted with the metal layer is removed to avoid short between the metal layers. The protective layer can protect the surface of the metal layer from being oxidized and thus the stability and the reliability of the semiconductor device can be effectively promoted.
