Abstract: An internal casing for a pressurized fluid storage tank for a motor vehicle includes: a hollow body includes a layer made of a first polymer material; and a neck arranged on the hollow body and delimiting an opening of the hollow body, the neck receiving an interface part mounted on the neck in a sealed manner by a gasket arranged between the neck and the interface part. The neck is made of a composite material composed of a second polymer material loaded with reinforcing fibers, the composite material having a deformation resistance than that of the first polymer material. The neck is joined to the hollow body by molecular entanglement of polymer chains of the first polymer material and polymer chains of the second polymer material. Methods for manufacturing such an internal casing, and a storage tank including such an internal casing are disclosed.

Abstract: Methods for forming fins with a straight profile by preventing fin bending during STI fill and annealing are disclosed. Embodiments include providing STI regions separated by Si regions, each topped with a hardmask; planarizing the STI regions; removing the hardmask over a portion of the Si regions, forming recesses; forming a conformal spacer layer over the STI regions and in the recesses; removing horizontal portions of the spacer layer; epitaxially growing Si in each recess, forming fins; and etching the STI regions and a remainder of the spacer layer down to the Si regions to reveal the fins.

Abstract: Disclosed herein are various methods for better height control of the finFET patterned fins. In one example, this invention begins by depositing or growing an oxide material, for example, silicon dioxide. This oxide material is then patterned and etched to open windows or trenches to the substrate where fins will be grown. If a common channel material is desired, it is epitaxially grown in the windows. Then, some windows are covered and one pole of fins (for example nFET) are epitaxially grown in the exposed windows. The previously masked windows are opened and the newly formed fins are masked. The alternate channel material is then grown. The masked fins are then un-masked and the oxide is recessed to allow the fins to protrude from the oxide. This invention also allows for different channel materials for NMOS and PMOS.

Abstract: Disclosed herein are methods for better variable height control of FinFET patterned fins. In one example, the method includes forming a layer on a substrate, patterning that layer to create trenches, and forming a common stack material in the trenches. Next, a pFET masking material is formed over a portion of the structure, and an nFET channel material is formed in the unmasked trenches. The pFET masking material is removed and an nFET masking material is formed over the portion of the structure that includes the nFET channel material, and a pFET channel material is formed in the unmasked trenches. Next, the unmasked patterned material is made flush with the pFET channel material, thereby creating a difference in height with the masked pattern material. Finally, the nFET masking material is removed and the patterned layer is recessed to expose pFET and nFET channel material fin structures of differing heights.

Abstract: FIN-FET ICs with adjustable FIN-FET channel widths are formed from a semiconductor layer (42). Fins (36) may be etched from the layer (42) and then some (46) locally shortened or the layer (42) may be locally thinned and then fins (46) of different fin heights etched therefrom. Either way provides fins (46) and FIN-FETs (40) with different channel widths W on the same substrate (24). Fin heights (H) are preferably shortened by implanting selected ions (A, B, C, etc.) through a mask (90, 90?, 94, 94?, 97, 97?) to locally enhance the etch rate of the layer (42) or some of the fins (36). The implant(s) (A, B, C, etc.) is desirably annealed and then differentially etched. This thins part(s) (42-i) of the layer (42) from which the fins (46) are then etched or shortens some of the fins (46) already etched from the layer (42). For silicon, germanium is a suitable implant ion.

Abstract: A semiconductor fabrication system and method are presented. A three dimensional multilayer integrated circuit fabrication method can include forming a first device layer and forming a second device layer on top of the first device layer with minimal detrimental heat transfer to the first layer by utilizing a controlled laser layer formation annealing process. A controlled laser crystallization process can be utilized and the controlled laser can include creating an amorphous layer; defining a crystallization area in the amorphous layer, where in the crystallization area is defined to promote single crystal growth (i.e. prevent multi-crystalline growth); and applying laser to the crystallization area, wherein the laser is applied in a manner that prevents undesired heat transfer to another layer.
