The present invention generally relates to a woven preform for reinforced composite materials and a method of making thereof. Specifically, the present invention is a method of machine weaving fiber preforms for polymer matrix composites that consist of closed perimeters with multiple intersecting members in their interiors. More specifically, the invention is a woven preform and a method of forming thereof with closed cells at the outer edges with continuous hoop reinforcement in each cell of the preform. The woven preform is woven flat in both the warp and weft directions, and then unfolded to achieve the final shape of the structure, and can be processed into composite structural components using known methods such as resin transfer molding or chemical vapor infiltration. Thus, complicated shapes of all sizes can be woven on a conventional loom using the instant method.

This invention provides facing materials for cementitious boards such as those including Portland cement or gypsum cores. The preferred facing material includes, in a first embodiment, a facing layer having an areal weight of about 300 grams/M², and an air permeability rating of no greater than about 300 CFM/ft² (FG 436-910 test method). The facing layer reduces the penetration of a slurry of cementitious material during the manufacture of a cementitious board, while permitting the water vapor from the slurry to pass therethrough. The facing materials of this invention can be designed to substantially eliminate the fouling of rolls used in continuous processing of such boards without the use, or with greatly reduced use, of costly viscosity control agents in the slurry. In addition, further embodiments of this invention can include binders, coatings or saturants which are designed to decrease pore size, increase or decrease the contact angle of liquids, or promote greater adhesion to cementitious cores, greater adhesion to other layers in the facing material, or greater adhesion or affinity to various types of adhesive compositions used to join cementitious boards to insulation and exterior finishing systems (EIS or EIFS).

A semiconductor interconnect structure including a semiconductor substrate, a semiconductor active device formed in the substrate, a layer of low-k dielectric material, a first patterned conducting layer, a second patterned conducting layer, and a cap layer formed thereon. The low-k material layer is formed over the semiconductor device. The first conducting line is formed in the low-k material layer and connected to the semiconductor active device. The second conducting line is formed in the low-k material layer but not electrically connected to the semiconductor active device. The cap layer is formed over the low-k material layer, the first and second conducting lines. The cap layer includes silicon and carbon. Since the adhesion strength between the cap layer and the patterned conducting layer is greater than the adhesion strength between the cap layer and the low-k material layer, the addition of second patterned conducting layer would eliminate the overall possibility of delamination between the surface where cap layer is in contact with the low-k material and the first and the second patterned conducting layers.
