The present invention provides a castle-like shaped protect or a periphery protect or a DC chop mask for forming staggered data line patterns in semiconductor devices so as to shift the adjacent data lines from one another so as to print contacts with larger areas at one end of each data line.

A method for forming a self-aligned overlay mark is disclosed. First, a first region, a second region and a main feature which is disposed between the first region and the second region all disposed on the substrate are provided. The first region defines a first edge and the second region defines a second edge. Second, a cut mask layer is formed to respectively cover the first region and the second region to expose the main feature. Next, the cut mask layer is determined if it is self-aligned with the second edge or the first edge, and creates a self-aligned overlay mark. Later, a main feature etching step is carried out to transfer the main feature into the substrate when the cut mask layer is determined to be self-aligned with the second edge or the first edge.

A method and apparatus are provided to in one aspect update data on a wireless mobile device. Available updates may include both mandatory and discretionary updates, where the mandatory updates are always installed on the wireless mobile device. In another aspect, a method and apparatus for of remotely instructing a wireless mobile device to perform a service is provided. The wireless mobile device receives a ping message that instructs it to retrieve further instruction for performing services actions on the wireless mobile device.
摘要:
An upper imperforate cap closes the uppermost end of a bailer and a lower imperforate cap closes the lowermost end of the bailer. In a preferred embodiment, screwthreads are formed in the uppermost and lowermost ends of the bailer and complemental screwthreads are formed in the upper and lower caps. By capping the opposite ends of a bailer, the bailer serves as its own container when the sample contained within it is shipped to a laboratory. This eliminates VOC devices, nozzles, and the concomitant contamination that may result from emptying a bailer in the field.

Catalyst composition for use in the polymerization of olefins comprise neutral metal complexes together with activators comprising non-aromatic boron compounds. Suitable activators are triisobutylboron together with trialkylaluminium compounds. Preferred complexes are metallocenes. The use of such activating systems obviates the need for expensive aluminoxanes or aromatic fluorine containing compounds.
摘要:
Redistribution layers for microfeature workpieces, and associated systems and methods are disclosed. One method for processing a microfeature workpiece system includes positioning a pre-formed redistribution layer as a unit proximate to and spaced apart from a microfeature workpiece having an operable microfeature device. The method can further include attaching the redistribution layer to the microfeature workpiece and electrically coupling the redistribution layer to the operable microfeature device.
