摘要： A semiconductor device has a P channel gate stack comprising a first metal type and a second metal type over the first metal type and an N channel gate stack comprising the second metal type in direct contact with a gate dielectric/etch stop layer stack. The N channel gate stack and the P channel gate stack are etched by a dry etch. Either the gate dielectric or etch stop can be in contact with the substrate. The etch stop layer prevents the dry etch of the first and second metal layers from etching through the gate dielectric and gouging the underlying substrate.

摘要： Heating a reaction chamber or other apparatus in the absence of product wafers to a “curing” temperature above a deposition temperature between the deposition of a film on a first set of semiconductor product wafers and the deposition of a film on a second set of semiconductor product wafers. In some embodiments, a boat with filler wafers is in the reaction chamber when the reaction chamber is heated to the curing temperature. In some examples, the films are deposited by a low pressure chemical vapor deposition (LPCVD) process. With some processes, if the deposition of a film on product wafers is at a temperature below a certain temperature, the film deposited with the product wafer on a boat, filler wafers, and/or other structures in the reaction chamber can cause contamination of product wafers subsequently deposited with a film in the presence of the boat and filler wafers. Contamination from these previously deposited films is inhibited by applying a curing temperature to the deposited fillers in the absence of the product wafers before a film is deposited on the next set of product wafers.

摘要： One or more impurities may be incorporated within a metal-containing layer of a metal-containing gate electrode to modify the work function of the metal-containing gate electrode of a transistor can affect the threshold voltage of the transistor. In one embodiment, the impurity can be used in a p-channel transistor to allow the work function of a metal-containing gate electrode to be closer to the valence band for silicon. In another embodiment, the impurity can be used in an n-channel transistor to allow the work function of a metal-containing gate electrode to be closer to the conduction band for silicon. In a particular embodiment, a boron-containing species is implanted into a metal-containing layer within the metal-containing gate electrode within a p-channel transistor, so that the metal-containing gate electrode has a work function closer to the valence band for silicon as compared to the metal-containing gate electrode without the boron-containing species.

摘要： A method and apparatus are described for forming a first inter-layer dielectric (ILD0) stack having a protective gettering layer (72) with a substantially uniform thickness. After forming device components (32, 33) on a substrate (31), a gap fill dielectric layer of SATEOS (52) is deposited over an etch stop layer of PEN ESL (42) and then planarized before sequentially depositing a gettering layer of BPTEOS (72) and capping dielectric layer (82) on the planarized gap fill dielectric layer (52). Once the ILD0 stack is formed, one or more contact openings (92, 94, 96) are etched through the ILD0 stack, thereby exposing the etch stop layer (42) over the intended contact regions.
