摘要:
A method for fabricating a microelectronic structure provides for forming a backfilling material layer at least laterally adjacent, and preferably laterally adjoining, a resist layer located over a substrate. Preferably, the resist layer comprises a surface treated resist layer. Optionally, the backfilling material layer may be surface treated similarly to the surface treated resist layer. Under such circumstances: (1) surface portions of the backfilling material layer and resist layer; and (2) remaining portions of the backfilling material layer and resist layer, may be sequentially stripped using a two step etch method, such as a two step plasma etch method. Alternatively, a surface portion of the surface treated resist layer only may be stripped while using a first etch method, and the remaining portions of the resist layer and backfilling material layer may be planarized prior to being simultaneously stripped while using a second etch method.

Disclosed are a flexible polymer, particles made from same, and a process for preparing the particles. This flexible polymer is obtained from copolymerizing monomer (A) and monomer (B), wherein monomer (A) is one or more water-insoluble unsaturated diene monomers; monomer (B) is at least one compound with the general formula of wherein R is C1-C12alkyl, C1-C12 alkyl aryl, C1-C12 alkyl ether or C1-C12alkyl ester. Monomer (A) is in an amount of 60-90% by weight of the total combined weight of monomer (A) and monomer (B). Monomer (B) is in an amount of 10-40% by weight of the total combined weight of monomer (A) and monomer (B). The flexible polymer particles show excellent flexibility, deformability, elasticity as well as stability. They can be used in oilfields in nearby wellbore profile control and in-depth profile control or as in-depth flooding fluid diverting agents. They can also be applied in water shutoff in high temperature and high salinity production wells; preventing chemical channeling in polymer and ASP (alkali-surfactant-polymer) flooding; temporarily plugging in acidization; huff and puff; and preventing in-depth channeling in steam flooding, loss of circulation control and filtration control, and the like.

An advanced method of patterning a gate stack including a high-k gate dielectric that is capped with a high-k gate dielectric capping layer such as, for example, a rare earth metal (or rare earth like)-containing layer is provided. In particular, the present invention provides a method in which a combination of wet and dry etching is used in patterning such gate stacks which substantially reduces the amount of remnant high-k gate dielectric capping material remaining on the surface of a semiconductor substrate to a value that is less than 1010 atoms/cm2, preferably less than about 109 atoms/cm2.

摘要:
Methods for fabricating a CMOS structure use a first gate stack located over a first orientation region of a semiconductor substrate. A second gate material layer is located over the first gate stack and a laterally adjacent second orientation region of the semiconductor substrate. A planarizing layer is located upon the second gate material layer. The planarizing layer and the second gate material layer are non-selectively etched to form a second gate stack that approximates the height of the first gate stack. An etch stop layer may also be formed upon the first gate stack. The resulting CMOS structure may comprise different gate dielectrics, metal gates and silicon gates.
摘要:
A method is presented for a time-aware strategy utilized within message-initiated constraint-based routing for digital message communication among nodes in an ad-hoc network, in which each node includes attributes. The method includes determining local attributes for each of the nodes and defining constraints on the attributes. Each node is provided access to the attributes of each neighboring node, with a neighboring node being a node that is one hop away. Each message transmitted over the network has a message type, which includes a destination specification, route specification, and objective specification. Constraint checking and cost estimation checking are performed for each message type. The message that is routed within the network includes the address of a sending node, address of the source node, route constraints, destination constraints specified with a time bound, the number of route constraints, the number of destination constraints, message identification number, sequence identification number, and routing objectives.
