摘要: A cluster system controls the interface properties of the films that deposit or grow on a silicon substrate. The system comprises a plurality of horizontal quartz chamber or tubes each of which can hold a large quantity of wafers, a transfer chamber and a load/unload chamber. Several process steps can be executed sequentially in different tubes without intermediate exposure to ambient air. A transfer chamber connects them and allows wafer transportation from one tube to another in an absolute controlled UHV environment which limits any contamination such as H2O, to less than a monolayer level. In addition, each tube can be pumped down to UHV pressure regime to avoid further cross contamination between tubes or particle generation. Since some of the process requires elevated temperature, all wafers are placed vertically on the quartz boat to prevent any wafer sagging as in a vertical furnace. Furthermore, before any wafers are placed into the transfer chamber, they are loaded into a load/unload chamber, which is the sole connection to the ambient air, to be purged and pumped so as to minimize particles and contamination.

摘要: A method for producing thin, below 6 nm of equivalent oxide thickness, germanium oxynitride layer on Ge-based materials for use as gate dielectric is disclosed. The method involves a two step process. First, nitrogen is incorporated in a surface layer of the Ge-based material. Second, the nitrogen incorporation is followed by an oxidation step. The method yields excellent thickness control of high quality gate dielectrics for Ge-based field effect devices, such as MOS transistors. Structures of devices having the thin germanium oxynitride gate dielectric and processors made with such devices are disclosed, as well.

摘要: A hydrogenated thin film is formed in a controlled vacuum on a substrate by evaporating one or more solid materials and passing the resulting vapor and a hydrogen-containing gas into a space between two electrodes. One of the electrodes includes openings for allowing the vapor to enter the space. Plasma is generated within the space to cause dissociation of the hydrogen-containing gas and promote a reaction between the material(s) and hydrogen-containing gas.

摘要: The present invention relates to semiconductor devices, and more particularly to a method for forming a CMOS semiconductor device, the method including a first integration anneal sequence for each NFET and a second integration anneal sequence for each PFET of the semiconductor device. The method includes providing a structure having an nFET gate stack and a pFET gate stack patterned on a substrate. A first disposable spacer is formed adjacent the nFET gate stack and a second disposable spacer is formed adjacent the pFET gate stack. A first doped S/D region and a second doped S/D region are then formed in the substrate. The first and second disposable spacers are removed after the first and second doped S/D regions are formed. A first halo implant and a first S/D extension region are formed adjacent the nFET gate stack after the first and second disposable spacers are removed. The structure is annealed using a RTA process. A first final spacer adjacent the nFET gate stack and the second final spacer adjacent the pFET gate stack are then formed after a second halo implant and a second S/D extension region are formed adjacent the pFET. The structure is annealed using a laser anneal process to form an NFET and a PFET on the substrate.
