摘要： Spaced-apart regions (2) each having top (2a) and side walls (2b) meeting at an edge (20) are defined on a surface (1a) of a substructure (1) forming part of the device. A layer (3) of insulating material is provided over the surface (1a) and regions (2), so that the insulating material is provided preferentially at the edges (20) of the regions (2) to form adjacent the edges (20) portions (31) of the insulating material which overhang the underlying insulating material (32) provided on the surface (1a) and define a void therein. The insulating material layer (3) is then etched anisotropically to expose the top walls (2a). During the anisotropic etching the overhanging portions (31) initially mask the underlying insulating material provided on the surface (1a) so that the etching of the underlying insulating material is controlled by the etching away of the overhanging portions (31) and when the top walls (2 a) are exposed relatively gently sloping spacers or portions (30) of the insulating material remain on the side walls (2b). A further insulating material layer (4) may then be provided over the structure.

摘要： A method of the kind consisting in that a contact is obtained with an active zone (11) carried by a semiconductor substrate (10) by means of conductive contact studs (18a) located in the contact openings (16c) of an isolating layer (12) and in that then a metallic configuration of interconnections (22) is formed establishing the conductive connection with the conductive contact studs (18a). A separation layer (13) is provided between the isolating layer (12) and the conductive layer (18), which can be eliminated selectively with respect to the islating layer (12). Thus, the isolating layer (12) retains its original flatness and the conductive contact studs (18a) have an upper level (20) exceeding slightly the level (21) of the isolating layer (12), thus favoring the contact between these contact studs (18a) and the metallic configuration of interconnections (22). Application in microcircuits having a high integration density.

摘要： The present disclosure provides small scale capacitors (e.g., DRAM capacitors) and methods of forming such capacitors. One exemplary implementation provides a method of fabricating a capacitor that includes sequentially forming a first electrode, a dielectric layer, and a second electrode. At least one of the electrodes may be formed by a) reacting two precursors to deposit a first conductive layer at a first deposition rate, and b) depositing a second conductive layer at a second, lower deposition rate by depositing a precursor layer of one precursor at least one monolayer thick and exposing that precursor layer to another precursor to form a nanolayer reaction product. The second conductive layer may be in contact with the dielectric layer and have a thickness of no greater than about 50 Å.

摘要： Disclosed is a container capacitor structure and method of constructing it. An etch mask and etch are used to expose portions of an exterior surface of electrode (“bottom electrodes”) of the container capacitor structure. The etch provides a recess between proximal pairs of container capacitor structures, which recess is available for forming additional capacitance. Accordingly, a capacitor dielectric and a top electrode are formed on and adjacent to, respectively, both an interior surface and portions of the exterior surface of the first electrode. Advantageously, surface area common to both the first electrode and second electrodes is increased over using only the interior surface, which provides additional capacitance without a decrease in spacing for clearing portions of the capacitor dielectric and the second electrode away from a contact hole location. Furthermore, such clearing of the capacitor dielectric and the second electrode portions may be done at an upper location of a substrate assembly in contrast to clearing at a bottom location of a contact via.

摘要： An ovonic phase-change semiconductor memory device having a reduced area of contact between electrodes of chalcogenide memories, and methods of programming the same are disclosed. Such memory devices include a lower electrode including non-parallel sidewalls. An insulative material overlies the lower electrode such that an upper surface of the lower electrode is exposed. In one embodiment, the insulative material and lower electrode may have a co-planar upper surface. In another embodiment, an upper surface of the lower electrode is within a recess in the insulative material. A chalcogenide material and an upper electrode are formed over the upper surface of the lower electrode. This allows the memory cells to be made smaller and allows the overall power requirements for the memory cell to be minimized.

摘要： The present disclosure provides methods and systems for controlling temperature. The method has particular utility in connection with controlling temperature in a deposition process, e.g., in depositing a heat-reflective material via CVD. One exemplary embodiment provides a method that involves monitoring a first temperature outside the deposition chamber and a second temperature inside the deposition chamber. An internal temperature in the deposition chamber can be increased in accordance with a ramp profile by (a) comparing a control temperature to a target temperature, and (b) selectively delivering heat to the deposition chamber in response to a result of the comparison. The target temperature may be determined in accordance with the ramp profile, but the control temperature in one implementation alternates between the first temperature and the second temperature.

摘要： A chip-scale or wafer-level-package, having passivation layers on substantially all surfaces thereof to form a hermetically sealed-package, is provided. The package may be formed by disposing a first passivation layer on the passive or backside surface of a semiconductor wafer. The semiconductor wafer may be attached to a flexible membrane and diced, such as by a wafer saw, to separate the semiconductor devices. Once diced, the flexible membrane may be stretched so as to laterally displace the individual semiconductor devices away from one another and substantially expose the side edges thereof. Once the side edges of the semiconductor devices are exposed, a passivation layer may be formed on the side edges and active surfaces of the devices. A portion of the passivation layer over the active surface of each semiconductor device may be removed so as to expose conductive elements formed therebeneath.

摘要： Disclosed herein are techniques for using diblock copolymer (DBCP) films as etch masks to form small dots or holes in integrated circuit layers. In an embodiment, the DBCP film is deposited on the circuit layer to be etched. Then the DCBP film is confined to define an area of interest in the DCBP film in which hexagonal domains will eventually be formed. Such confinement can constitute masking and exposing the DCBP film using photolithographic techniques. Such masking preferably incorporates knowledge of the domain spacing and/or grain size of the to-be-formed domains in the area of interest to ensure that a predictable number and/or orientation of the domains will result in the area of interest, although this is not strictly necessary in all useful embodiments. Domains are then formed in the area of interest in the DBCP film which comprises a hexagonal array of cylindrical domains in a matrix. The film is then treated (e.g., with osmium or ozone) to render either the domains or the matrix susceptible to removal, while the other component is then used as a mask to etch either dots or holes in the underlying circuit layer.

摘要： The present invention is related to methods and apparatus that allow a chalcogenide glass such as germanium selenide (GexSe1-x) to be doped with a metal such as silver, copper, or zinc without utilizing an ultraviolet (UV) photodoping step to dope the chalcogenide glass with the metal. The chalcogenide glass doped with the metal can be used to store data in a memory device. Advantageously, the systems and methods co-sputter the metal and the chalcogenide glass and allow for relatively precise and efficient control of a constituent ratio between the doping metal and the chalcogenide glass. Further advantageously, the systems and methods enable the doping of the chalcogenide glass with a relatively high degree of uniformity over the depth of the formed layer of chalcogenide glass and the metal. Also, the systems and methods allow a metal concentration to be varied in a controlled manner along the thin film depth.
