Abstract: Generally, according to the present invention, the sidewall of the adhesion layer (e.g. TiN 36) in a lower electrode is pre-oxidized after deposition of an unreactive noble metal layer (e.g. Pt 38) but before deposition of an HDC material (e.g. BST 42). An important aspect of the present invention is that the pre-oxidation of the sidewall generally causes a substantial amount of the potential sidewall expansion (and consequent noble metal layer deformation) to occur before deposition of the HDC material. One embodiment of the present invention is a microelectronic structure comprising a supporting layer having a principal surface, and an adhesion layer overlying the principal surface of the supporting layer, wherein the adhesion layer comprises a top surface and an expanded, oxidized sidewall (e.g. TiO.sub.2 40).

Abstract: A method for designing and operating a multi-processor computer system, in which data required for performing a task is determined by a first processor and then downloaded to a second processor that will execute the task. The data is associated with regions whose uses are expected by the second processor but whose actual contents are determined by the first processor. The method accommodates mutually exclusive access by both processors to memory of the second processor, while providing all data required for the task in a single read operation.

Abstract: A network (10) of mobile computing devices (18) communicates by receiving and rebroadcasting messages using wireless transmission. A message is initiated by first mobile computing device and transmitted to a set of other mobile computing devices which may be selected on an ad hoc basis. The receiving mobile computing devices rebroadcast the message to other of the mobile computing devices (18) which have not received the message. The message is repeatedly rebroadcast until all mobile computing devices (18) have received the message or, if the message is intended for particular selected mobile computing devices (18), until all selected devices have received the message.

Abstract: Portable electronic devices, such as notebook computers, are provided with the capability of a low profile and light weight keyboard, allowing greater reduction in the size and weight of portable computers without compromising the functionality. In specific embodiments, the present invention provides laptops, notebooks, and sub-notebooks with a low profile keyboard having a polymer top surface.

In response to the comparison, use of telephone system (16) through telephone network (20) is permitted.

Abstract: An apparatus and method for converting a subtractive device decode cycle to a peripheral component interface device decode cycle comprising a data communications bus (45), an interface (110) to the data communications bus (45), a function decoder (125) and device decoder (12) coupled to the interface (110). The function decoder (125) and device decoder (120) detect the presence of predetermined command and device types, respectively, on the data communications bus (45). The function decoder (125) and device decoder (120) feed a device select drive circuit (135) when the proper address and command types are detected. Device addresses in preselected ranges are pass-through and maintained internally in order to prevent the subtractive decode agent (90) from grabbing the bus cycle. Also, a positive decode cycle detection circuit (130) is operably coupled to the device select drive circuit (135) to detect the presence of positive decode cycles after the subtractive decode device select signal has been asserted.

Abstract: A fuse for a semiconductor integrated circuit is provided wherein a strip of corrosive material (82), such as aluminum, has one end thereof connected to a conductive strip (84) of a non-corrosive material and the other end thereof connected to a strip (94) of non-corrosive conductive material. The one end of the conductive strip (82) connected to the conductive strip (84) is connected through a contact (88). Similarly, the other end of the strip (82) is connected through a contact (96) to the non-corrosive conductive strip (94). The strips 84 and 94 provide a barrier to corrosion. This occurs whenever a break (104) is formed in the fuse to expose the ends of the fuse (82) at the break to a corrosive atmosphere. Alternatively, the fuse could be connected to corrosive underlying layers with contacts (118) and (124) of non-corrosive material such as a polysilicon or a polyside, or the active region of the substrate itself.

Abstract: In accordance with the present invention, there is provided a method by which narrow lateral dimensioned microelectronic structures can be formed using low temperature processes. An uncured resist layer (e.g. PMMA 42) is deposited on a supporting layer (e.g. silicon 40) and patterned. Then, by using an isotropic process such as a low temperature chemical vapor deposition, a conformal layer (e.g. silicon oxynitride 44) is deposited substantially evenly on the vertical walls and on the horizontal surfaces of the uncured resist layer. An anisotropic etch such as reactive ion etching is then used to substantially remove the conformal layer from the horizontal surfaces without substantially etching the conformal layer from the vertical walls of the resist. The resist can then be selectively removed, producing isolated vertical sidewall structures (e.g. silicon oxynitride 46) which could be used, for example, as a negative tone mask. Alternatively, instead of removing the resist, another resist layer (e.g.
