Abstract: A fabricating method of low temperature poly-silicon film is described. An amorphous silicon layer is formed on a substrate first; then, an anneal treatment is performed on the amorphous silicon layer for forming a poly-silicon layer (poly-silicon film) from the amorphous silicon layer. Several mounds are formed on the surface of the poly-silicon layer. A surface treatment step is performed; then, another laser anneal step is conducted on the poly-silicon layer. Since the size of these mounds on the surface of the poly-silicon layer can be reduced, the issue that the mounds are too big and have different sizes in the prior art can be resolved.

The internal layers are formed using conducting, resistive and high-k dielectric pastes available in standard LTCC fabrication and low-loss dielectric LTCC tape materials.

Abstract: This invention pertains to a method for making a trench capacitor of DRAM devices. A portion of the collar oxide layer is masked after the second polysilicon deposition and recess etching process.

The asymmetric collar oxide structure has a lower annular portion wrapping the second polysilicon layer and insulating the second polysilicon layer from the substrate, and an upper portion serving as a single-sided spacer for blocking diffusion of dopants from the third polysilicon stud to the substrate.

Abstract: Silicon carbide films are grown by carburization of silicon to form insulative films. In one embodiment, the film is used to provide a gate insulator for a field effect transistor. The film is grown in a microwave-plasma-enhanced chemical vapor deposition (MPECVD) system. A silicon substrate is fast etched in dilute HF solution and rinsed. The substrate is then placed in a reactor chamber of the MPECVD system in hydrogen along with a carbon containing gas. The substrate is then inserted into a microwave generated plasma for a desired time to grow the film. The microwave power varies depending on substrate size. The growth of the film may be continued following formation of an initial film via the above process by using a standard CVD deposition of amorphous SiC. The film may be used to form gate insulators for FET transistors in DRAM devices and flash type memories. It may be formed as dielectric layers in capacitors in the same manner.

Abstract: A method for fabricating MEMS structures includes etching a recess in either an upper surface of a substrate that is bonded to a wafer that ultimately forms the MEMS structure, or to the lower surface of the wafer that is bonded to the substrate. Accordingly, once the etching processes of the wafer are completed, the recess facilitates the release of an internal movable structure within the fabricated MEMS structure without the use of a separate sacrificial material. Furthermore, a bridge, which is preferably insulating, is pre-etched before the wafer is attached to the substrate.

Next, first, second, and third insulating spacers are successively formed over the sidewall of the gate structure. Subsequently, ion implantation is performed on the substrate on both sides of the gate structure using the third insulating spacer as a mask to form first doping regions. After the third insulating spacer is removed, ion implantation is performed on the substrate on both sides of the gate structure using the second insulating spacer as a mask to form second doping regions serving as source/drain regions with the first doping regions. Finally, after the second insulating spacer is removed, ion implantation is performed on the substrate on both sides of the gate structure using the first insulating spacer as a mask to form third doping regions, thereby preventing punchthrough.
