A method for depositing a low dielectric constant film is provided by reacting a gas mixture including one or more linear, oxygen-free organosilicon compounds, one or more oxygen-free hydrocarbon compounds comprising one ring and one or two carbon-carbon double bonds in the ring, and one or more oxidizing gases. Optionally, the low dielectric constant film is post-treated after it is deposited. In one aspect, the post treatment is an electron beam treatment.

The present invention provides a method of forming a semiconductor structure having an ultra low-K dielectric material that adheres well to the substrate. The method includes depositing a low-K material on the top surface of a substrate at a low temperature of no more than 250° by a CVD or spin-on process. The dielectric material is then cured by placing the substrate with the dielectric film in an environment where the temperature is regulated at about 400° or less as the dielectric film is being subjected to a plasma treatment or an E-beam treatment or UV treatment. The environment may further include one or more gases or a mixture of gases selected from the group consisting of H₂, N₂, NH₃, CO₂, all hydride gases and a mixture of these gases.

Methods for improving the mechanical properties of a CDO film are provided. The methods involve, for instance, providing either a dense CDO film or a porous CDO film in which the porogen has been removed followed by curing the CDO film at an elevated temperature using either a UV light treatment, an e-beam treatment, or a plasma treatment such that the curing improves the mechanical toughness of the CDO dielectric film.

The present invention generally provides a method for depositing a low dielectric constant film using an e-beam treatment. In one aspect, the method includes delivering a gas mixture comprising one or more organosilicon compounds and one or more hydrocarbon compounds having at least one cyclic group to a substrate surface at deposition conditions sufficient to deposit a non-cured film comprising the at least one cyclic group on the substrate surface. The method further includes substantially removing the at least one cyclic group from the non-cured film using an electron beam at curing conditions sufficient to provide a dielectric constant less than 2.5 and a hardness greater than 0.5 GPa.

It has now been surprisingly found that by exposing a photoresist to flood electron beam exposure in combination with optical exposure, that the pullback on the upper region of lithographic images in resist can be virtually eliminated during electron beam processing. This unexpected result is due to the fact that the electron beam exposure and optional bake are carried out prior to development of the resist. This means that the resist shrinkage that is seen as a result of these steps is constrained laterally by the resist film itself. Thus, the resist is free to shrink vertically, and the resulting shrinkage provides a reduction in the line slimming and an improvement in the etch rate of the resist. This leads to the formation of a better resist image.

A porous dielectric film for use in electronic devices is disclosed that is formed by removal of soluble nano phase porogens. A silicon based dielectric film having soluble porogens dispersed therein is prepared by chemical vapor deposition (CVD) or by spin on glass (S.O.G.). Examples of preferable porogens include compounds such as germanium oxide (GeO₂) and boron oxide (B₂O₃). Hot water can be used in processing to wet etch the film, thereby removing the porogens and providing the porous dielectric film. The silicon based dielectric film may be a carbon doped silicon oxide in order to further reduce the dielectric constant of the film. Additionally, the porous dielectric film may be treated by an electron beam to enhance the electrical and mechanical properties of the film.

A textured, layered mold-formed body is produced with a foil laminate in which a top foil of at most partially crosslinked polymer materials and a sub-foil containing a polymer foam material with a density between 35 and 120 grams per liter and a gel content of less than 80 percent are laminated together. The foil laminate is embossed with a texture and treated with electron beams to give the texture enough stability for a subsequent deep-drawing step in which the mold-formed body is produced.

A controller is configured to modulate an ebeam to ensure that a non-continuously moving web is sterilized within a desired range of exposure. During sterilization in place operations, manifolds are configured to operate to ensure that sterilants do not enter an irradiation zone to prevent damage to ebeam emitters.

Generally, a method and apparatus for forming an elastic portion of an absorbent article is disclosed. An elastic material web having at least one crosslinkable elastic styrenic block copolymer sized to correspond to at least one discrete elasticized portion of the absorbent article is provided. The elastic material web may be unwound or otherwise supplied and then attached to a continuous moving web to form at least one discrete elasticized portion of the absorbent article. The elastic material web is crosslinked by subjecting the elastic material web to electromagnetic radiation with an electron beam processing unit sufficient to provide a crosslinked elastic styrenic block copolymer. The electromagnetic radiation is sized to correspond to at least one discrete elasticized portion of the absorbent article. A variety of absorbent article components may possess elastic characteristics, including waistbands, leg/cuff gasketing, side panels, and outer covers.

As a rule, electron beam welding takes place in a vacuum. However, this means that the workpieces in question have to be placed in a vacuum chamber and have to be removed therefrom after welding. This is time-consuming and a serious limitation of a process the greatest advantage of which is the option of welding workpieces of large thicknesses. Therefore the idea is to guide the electron beam (2) to the workpiece via a hollow wire, said wire thereby acting as a prolongation of the vacuum chamber (4) down to workpiece. Thus, a workpiece need not be placed inside the vacuum chamber, thereby exploiting the potential of electron beam processing to a greater degree than previously possible, for example by means of electron beam welding.

The invention relates to the field of quantum sensing and particularly relates to a non-magnetic temperature control system of a solid-state atomic spin sensor. The system comprises a diamond substrate. The diamond substrate is provided with a diamond NV color-center waveguide (4). The diamond substrate is further provided with a porous magnetic PDMS film (3) configured to cover the diamond NV color-center waveguide (4). The two sides of the lower surface of the diamond substrate are provided with a micro-strip antenna array (2). The micro-strip antenna array (2) is connected with a microwave source. According to the technical scheme of the invention, a nitrogen-doped diamond structure, larger than 1018 cm<-1> in concentration, is prepared by adopting the MPCVD magneto-electric restraint method, and a diamond color-center structure is prepared by adopting the micro-nano processing technology. Therefore, the excitation and fluorescence collection of the NV color-center structure are realized. Meanwhile, the coplanar manufacturing of a microwave antenna is realized in combination with the electron beam processing method. Moreover, the high signal-to-noise ratio detection of magnetic variation signals is carried out by adopting the time sequence control method, so that the effect of a temperature-modulated magnetic field is realized. The magnetic noise is effectively inhibited, and the purpose of non-magnetic temperature control is achieved.
