摘要:
A method of fabricating and a structure of an IC incorporating strained MOSFETs on separated silicon layers are disclosed. N-channel field effect transistors (nFET) and P-channel FETs (pFET) are formed on the separated silicon layers, respectively. Shallow trench insulation (STI) regions adjacent to the nFETs and pFETs thus can be formed to induce different stress to the channel regions of the respective nFETs and pFETs. As a consequence, performance of both the nFETs and the pFETs can be improved by the STI stress. In addition, the area of the IC can also be reduced as the two silicon layers are positioned vertically relative to one another.

A semiconductor structure includes a semiconductor device including a contact region. The semiconductor structure also includes a passivation layer passivating the semiconductor device including the contact region. A narrow bottomed stepped sidewall contact aperture is located within the passivation layer to expose the contact region. A corresponding narrow bottomed stepped sidewall contact via is located within the narrow bottomed stepped sidewall contact aperture to contact the contact region. The narrow bottomed stepped sidewall contact aperture and contact via provide for improved contact to the contact region and reduced parasitic capacitance with respect to the semiconductor device. Methods for fabricating the narrow bottomed stepped sidewall contact aperture use a mask layer (either dimensionally diminished or dimensionally augmented) in conjunction with a two step etch method.

A method in which during the formation of damascene features in a semiconductor structure, a planarization material is added to vias formed in the dielectric to protect the vias during subsequent lithographic processing. The planarization material preferred is a developable photosensitive material which can be exposed and developed to define the damascene features rather than etching as is conventional.

A method of preventing resist line collapse in damascene structures and a structure thereof is disclosed. A damascene pattern for resist lines is enhanced with ribs extending therefrom. The ribs provide mechanical support for resist lines and improve the lithography process for forming the resist lines, particularly when a negative focus is used. The ribs may extend between vias in an underlying material layer. The method results in structurally strong resist lines for damascene structures that are less likely to collapse.

A safety lighter includes a lighter body comprising a casing defining a liquefied gas chamber for containing a predetermined volume of liquefied gas therein, a supporting frame having an outer sealing surface engaged with an inner surface of the casing, a gas emitting nozzle mounted on the supporting frame to communicate with the liquefied gas chamber, and an ignition device supported by the supporting frame for ignition. A sealing arrangement includes upper and lower sealing rims spacedly and integrally provided along an opening portion of the inner surface of the casing in a step-shouldering manner wherein the upper and lower sealing rims are sealed with the outer sealing surface of the supporting frame to form two sealing lines along the upper and lower sealing rims respectively to sealedly mount the supporting frame on the lighter body for sealedly retaining the liquefied gas within the liquefied gas chamber.

A handheld atmospheric pressure glow discharge plasma source is provided without the use of an arc. The plasma is induced using a radio frequency signal. An LC resonator in the handheld source with a gain of about 10 at 13.56 MHZ improves the power transfer from a power supply and tuner to the plasma chamber which is capable of producing stable plasmas in Ar, He and O.sub.2 mixtures.
摘要:
A method for fabricating thin-film multilayer interconnect signal planes for connecting semiconductor integrated circuits (chips) is described. In this method, a first pattern of thin-film metallic interconnect lines is formed on a surface of a substrate. Then a first dielectric layer is formed over the entire surface of the substrate covering the pattern of thin-film metallic interconnect lines. A portion of the dielectric layer is then removed to expose the thin-film metallic interconnect lines so that a series of trenches is formed above each interconnect line. The interconnect lines are then electroplated to form a series of thicker metal interconnect lines such that the thicker metal interconnect lines and the dielectric layer form a substantially planar surface. This process can then be repeated in its entirely to form a plurality of interconnect signal planes. In the preferred embodiment, metallic vias are provided between each layer of metallic interconnect lines for electrical connection purposes.
