In a process for producing an oriented inorganic crystalline film, a non-monocrystalline film containing inorganic crystalline particles is formed on a substrate by a liquid phase technique using a raw-material solution which contains a raw material and an organic solvent, where the inorganic crystalline particles have a layered crystal structure and are contained in the raw material. Then, the non-monocrystalline film is crystallized by heating the non-monocrystalline film to a temperature equal to or higher than the crystallization temperature of the non-monocrystalline film so that part of the inorganic crystalline particles act as crystal nuclei.

Semiconductor thin film forming method, production methods for semiconductor device and electrooptical device, devices used for these methods, and semiconductor device and electrooptical device

An object of the present invention is to provide a method for easily forming a polycrystalline semiconductor thin-film, such as polycrystalline silicon having high crystallinity and high quality, or a single crystalline semiconductor thin-film at inexpensive cost, the crystalline semiconductor thin-film having a large area, and to provide an apparatus for processing the method described above. In forming a polycrystalline (or single crystalline) semiconductor thin-film (7), such as a polycrystalline silicon thin-film, having high crystallinity and a large grain size on a substrate (1), or in forming a semiconductor device having the polycrystalline (or single crystalline) semiconductor thin-film (7) on the substrate (1), a method comprises forming a low-crystallization semiconductor thin-film (7A) on the substrate (1), and subsequently heating and cooling this low-crystallization semiconductor thin-film (7A) to a fusion, a semi-fusion, or a non-fusion state by flash lamp annealing to facilitate the crystallization of the low-crystallization semiconductor thin-film, whereby a polycrystalline (single crystalline) semiconductor thin-film (7) is obtained. A method for forming the semiconductor device and an apparatus for processing the methods are also disclosed.

Structure and method of making strained semiconductor CMOS transistors having lattice-mismatched source and drain regions

A p-type field effect transistor (PFET) and an n-type field effect transistor (NFET) of an integrated circuit are provided. A first strain is applied to the channel region of the PFET but not the NFET via a lattice-mismatched semiconductor layer such as silicon germanium disposed in source and drain regions of only the PFET and not of the NFET. A process of making the PFET and NFET is provided. Trenches are etched in the areas to become the source and drain regions of the PFET and a lattice-mismatched silicon germanium layer is grown epitaxially therein to apply a strain to the channel region of the PFET adjacent thereto. A layer of silicon can be grown over the silicon germanium layer and a salicide formed from the layer of silicon to provide low-resistance source and drain regions.
