A method includes forming a PMOS device. The method includes forming a gate dielectric layer over a semiconductor substrate and in a PMOS region, forming a first metal-containing layer over the gate dielectric layer and in the PMOS region, performing a treatment on the first metal-containing layer in the PMOS region using an oxygen-containing process gas, and forming a second metal-containing layer over the first metal-containing layer and in the PMOS region. The second metal-containing layer has a work function lower than a mid-gap work function of silicon. The first metal-containing layer and the second metal-containing layer form a gate of the PMOS device.

The present disclosure provides a method of fabricating a semiconductor device. The method includes forming a plurality of dummy gates over a substrate. The dummy gates extend along a first axis. The method includes forming a masking layer over the dummy gates. The masking layer defines an elongate opening extending along a second axis different from the first axis. The opening exposes first portions of the dummy gates and protects second portions of the dummy gates. A tip portion of the opening has a width greater than a width of a non-tip portion of the opening. The masking layer is formed using an optical proximity correction (OPC) process. The method includes replacing the first portions of the dummy gates with a plurality of first metal gates. The method includes replacing the second portions of the dummy gates with a plurality of second metal gates different from the first metal gates.

A method of fabricating a laterally diffused metal oxide semiconductor (LDMOS) transistor includes forming a dummy gate over a substrate. A source and a drain are formed over the substrate on opposite sides of the dummy gate. A first silicide is formed on the source. A second silicide is formed on the drain so that an unsilicided region of at least one of the drain or the source is adjacent to the dummy gate. The unsilicided region of the drain provides a resistive region capable of sustaining a voltage load suitable for a high voltage LDMOS application. A replacement gate process is performed on the dummy gate to form a gate.

Compositions, pharmaceutical preparations and methods are disclosed for protecting non-neoplastic cells from damage caused by cancer chemotherapeutic agents or radiation therapy, during the course of cancer therapy or bone marrow transplant. These are based on the use of chemoprotective inducing agents that induce or increase production of cellular detoxification enzymes in target cell populations. The compositions and methods are useful to reduce or prevent hair loss, gastrointestinal distress and lesions of the skin and oral mucosa that commonly occur in patients undergoing cancer therapy. Also disclosed is a novel assay system for identifying new chemoprotective inducing agents.

The present invention relates to a medical stent, and in particular to a cardia stent for treatment on the narrow carida of the oesophagus. The cardia stent according to the present invention is woven by wires of shape memory NiTi alloy. There is a drum-shaped locating port at its upper end, and a trumpet-shaped locating port at its lower end. The upper drum-shaped locating port is connected with the lower trumpet-shaped locating port by a supporting net tube. The remaining portions other than the drum-shaped locating port are coated with a membrane of medical flexible material that can be implanted into a human body. The cardia stent comprises at least an anti-reflux valve. The anti-reflux valve is of a triple-petal structure protruding downward that is made from a membrane of medical flexible material that can be implanted into a human body. The cardia stent has the advantages of: difficult to shift, matching with carida anatomy, high anti-reflux ability, easy operation, resisting the corrosion of gastric juice, and it can be used in expansion treatment on the narrow carida caused by variable reasons.
