Adhesives having a microreplicated topography are prepared from contacting a microembossed pattern to a layer of adhesive. When an adhesion interface is established between the layer of adhesive and a supporting substrate, the topography of the adhesive surface controls the performance of the adhesion interface. Articles having microreplicated adhesive surfaces are also disclosed that have an advantage of providing microchannels for fluid egress for an effective period of time. Multiple microembossed patterns produce microreplicated adhesive surfaces having both microchannels for fluid egress and pegs for improved adhesive properties.

A computer system representing user preferences in an N-dimensional preference topography and making recommendations based on such topography. The preference topography depicts user ratings of products in a recommendation database. Each product is represented by a product vector associated with N objectively measurable characteristics. The user rating of a product, therefore, represents the user's preference for the particular combination of the N objectively measurable characteristics making up the product. In making a recommendation of products to the user, the system assigns a rating to each product in the recommendation database based on the preference topography. The system then selects a plurality of maximally unique choices from the rated products for recommendation to the user. These maximally unique choices are calculated to be as diverse from one another as possible but still to the user's liking. In another embodiment of the invention, the system identifies portions of the N-dimensional rating space for which the user has indicated a positive association (a positive preference cluster) or a negative association (a negative preference cluster). In making a recommendation of a potential product, the system determines the similarities of products that fall in the positive preference cluster with the potential product. The system also takes into account the products that fall in the nearest negative cluster and determines the similarities with such products and the potential product. In one particular aspect of the invention, the system presents a virtual character for making the usage of the system more user-friendly and interesting. The virtual character is programmed to interact with the user for obtaining user ratings of products and thus determining where the user preferences lie.

A scheme for aligning opaque material layers of a semiconductor device. Alignment marks are formed in a via level of the semiconductor device. The alignment marks are formed using a separate lithography mask, and may have about the same length as vias formed in the via layer. The alignment marks comprise trenches that are not filled with material and are not exposed to a CMP process. An opaque material layer is deposited, and depressions are formed in the opaque material layer over the alignment mark trenches. The depressions in the opaque material layer are used to align a lithography process to open the opaque material layer over alignment marks in an underlying metallization layer. The alignment marks in the metallization layer are then used to align the lithography process used to pattern the opaque material layer.

Network topography may be discovered by a network element on an Ethernet network by collecting connectivity check messages periodically issued by other network elements on the network and using the information gleaned from those messages to build a topography database. Since the connectivity check messages may be link level or service instance based, the topography database may include network topography as well as service topography on the Ethernet network. Ethernet OAM loopback frames may also be used to cause network elements on the Ethernet network to issue response frames directed to the initiating network element. By collecting responses from the responding network elements, the initiating network element can build a topography database of network elements on the Ethernet network. This topography database may show the overall network topography or service instances on the network, and may provide visibility within one or more domains.

Link-based source routing may be implemented using generic framing protocol (GFP) to enable GFP frames to contain a switching context that will allow them to be forwarded on a network without requiring state information to be distributed to interior network elements on the network. Source routes may be computed from network topography information obtained using OSPF or ISIS. An extension header type is added to the GFP frames to signal to the network elements that the GFP frame contains a link-based source route. The source route contains a vector of tunnel IDs and a pointer to the current hop, to enable the current tunnel ID to be determined. The tunnel IDs have local significance only, and hence state information is not required to be distributed on the network. A return route may be built by index substitution as the frame traverses the network.

A pattern having exceptionally small features is formed on a partially fabricated integrated circuit during integrated circuit fabrication. The pattern comprises features formed by self-organizing material, such as diblock copolymers. The organization of the copolymers is directed by spacers which have been formed by a pitch multiplication process in which spacers are formed at the sides of sacrificial mandrels, which are later removed to leave spaced-apart, free-standing spacers. Diblock copolymers, composed of two immiscible block species, are deposited over and in the space between the spacers. The copolymers are made to self-organize, with each block species aggregating with other block species of the same type.

Methods and systems are provided which are adapted to process a microelectronic topography, particularly in association with an electroless deposition process. In general, the methods may include loading the topography into a chamber, closing the chamber to form an enclosed area, and supplying fluids to the enclosed area. In some embodiments, the fluids may fill the enclosed area. In addition or alternatively, a second enclosed area may be formed about the topography. As such, the provided system may be adapted to form different enclosed areas about a substrate holder. In some cases, the method may include agitating a solution to minimize the accumulation of bubbles upon a wafer during an electroless deposition process. As such, the system provided herein may include a means for agitating a solution in some embodiments. Such a means for agitation may be distinct from the inlet / s used to supply the solution to the chamber.

A mask having features formed by self-organizing material, such as diblock copolymers, is formed on a partially fabricated integrated circuit. Initially, a copolymer template, or seed layer, is formed on the surface of the partially fabricated integrated circuit. To form the seed layer, diblock copolymers, composed of two immiscible blocks, are deposited in the space between copolymer alignment guides. The copolymers are made to self-organize, with the guides guiding the self-organization and with each block aggregating with other blocks of the same type, thereby forming the seed layer. Next, additional, supplemental diblock copolymers are deposited over the seed layer. The copolymers in the seed layer guide self-organization of the supplemental copolymers, thereby vertically extending the pattern formed by the copolymers in the seed layer. Block species are subsequently selectively removed to form a pattern of voids defined by the remaining block species, which form a mask that can be used to pattern an underlying substrate. The supplemental copolymers augment the height of the copolymers in the seed layer, thereby facilitating the use of the copolymers for patterning the underlying substrate.
