摘要： A memory cell comprising a ferroelectric capacitor, a variable impedance element and a conductive load is disclosed. The ferroelectric capacitor, characterized by first and second polarization states, is connected between a control terminal and a first switch terminal. The variable impedance element has an impedance between the first and second switch terminals that is determined by a signal on a control terminal. The conductive load is connected between a first power terminal and the first switch terminal. The second switch terminal is connected to a second power terminal. When a potential difference is applied between the first and second power terminals, a potential on the first switch terminal varies in a manner determined by the state of polarization of the ferroelectric capacitor.

摘要： A method for fabricating an integrated circuit having at least one integrated circuit component (14) fabricated in a silicon substrate (12) and a second device (30) that is to be fabricated on a silicon oxide layer (16) that covers the integrated circuit component (14). The integrated circuit component (14) has a terminal that is to be connected to a corresponding terminal on the second device (30). The second device (30) includes an electrode structure (35) in contact with a dielectric component that includes a layer (33) of ferroelectric material. In the method of the present invention, a boundary layer comprising non-conducting polysilicon (17) is deposited over the silicon oxide layer (16). The electrode structure (35) is then fabricated by depositing one or more layers over the boundary layer (17). The ferroelectric layer (33) is then deposited over the electrode structure (35) and etched to provide the dielectric component. The boundary layer is then removed utilizing an etchant that etches silicon oxide much slower than polysilicon.

摘要： A method for connecting a silicon substrate to an electrical component via a platinum conductor. A capacitor (40) can be built over the source (34) of a transistor (32). Cell (30) is constructed by first constructing a CMOS transistor (32) having a drain (33), gate region consisting of gate oxide (35) and gate electrode (36), and source (34). The gate structures are insulated with a glass layer (37). A capacitor (40) is then constructed by depositing a bottom electrode (42) on source (34). A ceramic layer (43) is then deposited and sintered. Finally, the top electrode (41) is deposited. The resulting structure may be heated in the presence of oxygen to a temperature in excess of 800 DEG C without destroying the electrical connection between the silicon substrate and components connected to the platinum conductor. The present invention utilizes a TiN or TiW buffer layer to connect the platinum conductor to the silicon substrate. The buffer layer is deposited as a single crystal on the silicon substrate. The platinum layer is then deposited on the buffer layer. The region of the platinum layer in contact with the buffer layer is also a single crystal.

摘要： A ferroelectric memory cell (200) for storing information. The information is stored in the remnant polarization of a ferroelectric dielectric layer (213) by setting the direction of the remnant polarization. The ferroelectric memory cell is designed to store the information at a temperature less than a first temperature. The memory cell includes top and bottom contacts that sandwich the dielectric layer (213) which includes a ferroelectric material having a Curie point greater than the first temperature and less than 400 °C. The dielectric layer (213) is encapsulated in an oxygen impermeable material such that the encapsulating layer (221) prevents oxygen from entering or leaving the dielectric layer (213). The memory also includes a hydrogen barrier layer (225) that inhibits the flow of oxygen to the top and bottom electrodes when the memory cell is placed in a gaseous environment containing hydrogen. In one embodiment of the invention, a hydrogen absorbing layer is included. In the preferred embodiment of the present invention, the hydrogen barrier layer (225) is constructed from a material that will also bind hydrogen ions.

摘要： A shipping container system comprises an inner liner (1) for insertion into an inner shipping container (15), for insertion into an outer shipping container (16). The inner liner (1) comprises a layer of single- or double-bubble radiant barrier material (13) within a sealed vinyl pouch (21). Between the outer container (6) and the inner container (5) there is furnished at least one spacer tray (3), for providing a partially-surrounding pocket of air in contact with the exterior surface of the inner container (5). During sealing of the pouch (21), a pocket of air is allowed to remain in its interior so that the radiant barrier material (13) floats within the sealed pouch (21). The pockets of air provided allow for maximization of the thermal insulating properties of the system due primarily to the thermal reflective property of the radiant barrier material. The vinyl construction of the pouch material provides a durable protective cover for the radiant barrier material.
