摘要： A layer of silicon nitride having a thickness from 0.5 nanometers to 2.4 nanometers is deposited on a substrate. A plasma nitridation process is carried out on the layer. These steps are repeated for a plurality of additional layers of silicon nitride, until a predetermined thickness is attained. Such steps can be used to provide a multilayer silicon nitride dielectric formed on a substrate having an upper surface of dielectric material with Cu and other conductors embedded within, and a plurality of steps. The multilayer silicon nitride dielectric has a plurality of individual layers each having a thickness from 0.5 nanometers to 2.4 nanometers, and the multilayer silicon nitride dielectric conformally covers the steps of the substrate with a conformality of at least seventy percent. A multilayer silicon nitride dielectric, and a multilevel back end of line interconnect wiring structure using same, are also provided.

摘要： A dielectric capping layer having a dielectric constant of less than 4.2 is provided that exhibits a higher mechanical and electrical stability to UV and/or E-Beam radiation as compared to conventional dielectric capping layers. Also, the dielectric capping layer maintains a consistent compressive stress upon post-deposition treatments. The dielectric capping layer includes a tri-layered dielectric material in which at least one of the layers has good oxidation resistance, is resistance to conductive metal diffusion, and exhibits high mechanical stability under at least UV curing. The low k dielectric capping layer also includes nitrogen content layers that contain electron donors and double bond electrons. The low k dielectric capping layer also exhibits a high compressive stress and high modulus and is stable under post-deposition curing treatments, which leads to less film and device cracking and improved device reliability.

摘要： Polysilicon in a trench is etched at an angle to produce a conductor within the trench that has shape characteristics which approximate the shadow of the side wall of the trench closest the beam source. Specifically, when the first side wall is closest to the beam source and the second side wall is furthest from the beam source, the polysilicon on the first side wall is almost as high as the first side wall, while the polysilicon on the more exposed side wall is considerably lower than the first side wall and approximates the shadow of the first side wall on the second side wall relative to the beam. The polysilicon in the trench may be in the shape of a solid angled block approximating the shadow line from the top of side wall to the shadow line on side wall however, it is preferred that the polysilicon take the form of a conformal layer in trench prior to etching such that the polysilicon ultimately has an angled "U" shape which approximates the shadow line. Contact is made to the polysilicon using strap that electrically connects the side wall with the polysilicon. Strap is sized such that it does not extend to the opposite side wall of trench, thereby avoiding short circuits. Having the polysilicon approximate the shadow line of the etch permits narrowing the distance between adjacent straps and in an array without the risk of creating a short.

摘要： Integrated circuit structures of sub-lithography dimensions are formed by conformal deposition of alternating layers of materials having differing etch rates within an aperture over a body of material to be etched. One of the materials in the alternating layers is then selectively and preferentially etched to form a mask through which etching can be performed on the body of material to be etched. This technique is particularly suited to the formation of structurally robust capacitors for memory cells which have greatly increased plate area, resulting in increased capacitance, while maintaining a small footprint for the capacitor structure.

摘要： A glide head is used to test a rigid magnetic disk surface for projecting asperities. Using a two rail head with the read/write transducer mounted at the rear of the rail at the side of the head toward which the head is being radially advanced and skewing the head so that the trailing edge of the head approaches each track before the leading edge as the head is advanced, it is possible to write a pattern from a known position relative an event or asperity identified by a mechanical transducer associated with the head to the index location. Using a developer, it is then possible to readily identify the asperity during microscopic examination of the disk surface.

摘要： A two-part implantable heart valve and procedure are disclosed that allow expansion and positioning of a first part of the implantable heart valve having a temporary or transient valvular structure. A second part of the implantable heart valve is deployed within the first part and attaches thereto. The valvular structure of the second part then acts to function as the heart valve replacement. A tool or system is provided for determining an adequate percutaneous heart valve size for a given stenotic valve. A balloon can be inflated inside the stenotic valve to a desired pressure. When this pressure is reached an angiographic image is taken and the balloon diameter is measured at a waist area created by contact between the balloon and the stenotic valve. The diameter represents the minimum percutaneous heart valve diameter to be implanted.
