A method of forming an integrated circuit includes providing a buffer layer comprising a dielectric material above a layer of conductive material and providing a layer of mask material above the buffer layer. The mask material comprises amorphous carbon. The method also includes removing a portion of the buffer layer and the layer of mask material to form a mask. A feature is formed in the layer of conductive material according to the mask.

A method includes forming a group of first structures on a semiconductor device and forming spacers adjacent side surfaces of each of the first structures to form a group of second structures. The method further includes using the group of second structures to form at least one sub-lithographic opening in a material layer located below the group of second structures.

An amorphous carbon layer of an antireflective bi-layer hardmask is processed to increase its density prior to patterning of an underlying polysilicon layer using the bi-layer hardmask. The increased density of the layer increases its resistance to polysilicon etch chemistry, thus reducing the likelihood of patterning inaccuracies resulting from amorphous carbon depletion during polysilicon etch, and enabling the patterning of thicker polysilicon layers than can be reliably patterned without densification. The increased density also reduces stresses, thus reducing the likelihood of delamination. Densification may be performed by UV or e-beam irradiation after formation of an overlying protective layer. Densification may also be performed by annealing the amorphous carbon layer in situ prior to formation of the overlying protective layer. In the latter case, annealing reduces the amount of outgassing that occurs during formation of the protective layer, thus reducing the formation of pin holes.

A method of producing an integrated circuit includes providing a layer of polysilicon material above a semiconductor substrate and providing an amorphous carbon layer over the polysilicon material layer. The amorphous carbon layer comprises at least one undoped amorphous carbon layer and at least one doped amorphous carbon layer. A portion of the amorphous carbon layer is removed to form a hard mask, and the polysilicon material layer is etched according to the hard mask to form a line of polysilicon material.

The present invention provides a package assembly that incorporates a foamable topping under pressure and provides the consumer with a fresh, foamed topping when the package is opened. In one version, the topping material is carried under pressure on top of the liquid contents of the package, and foams when the package is opened. In other versions the topping is carried within the cap or cover of the package, and is selectively dispensed by the consumer after the package has been opened.
摘要:
A method of producing an integrated circuit eliminates the need to re-oxidize polysilicon gate conductors and lines prior to removal of a hard mask used to form the gate conductors. A layer of polysilicon is provided above a semiconductor substrate. The layer of polysilicon is then doped. A mask material comprising amorphous carbon is provided above the layer of polysilicon, and the layer of mask material is patterned to form a mask. A portion of the layer of polysilicon is removed according to the mask, and the mask is removed.

A method of manufacturing for a Flash memory includes depositing a charge-trapping material over a semiconductor substrate and implanting first and second bitlines. A wordline material is deposited over the charge-trapping dielectric material and a hard mask material deposited. A disposable anti-reflective coating (ARC) material and a photoresist material are deposited followed by processing to form a patterned photoresist material and a patterned ARC material. The hard mask material is processed to form a patterned hard mask material. The patterned photoresist is removed and then the patterned ARC without damaging the patterned hard mask material or the wordline material. The wordline material is processed using the patterned hard mask material to form a wordline and the patterned hard mask material is removed without damaging the wordline or the charge-trapping dielectric material.
