A structure with an interconnection layer for redistribution of electrical connections includes a plurality of first electrical connections disposed on a substrate in a first arrangement. An insulating layer is disposed on the substrate over the first electrical connections. A plurality of second electrical connections is disposed on the insulating layer on a side of the insulating layer opposite the plurality of first electrical connections in a second arrangement. Each second electrical connection is electrically connected to a respective first electrical connection. An integrated circuit is disposed on the substrate and is electrically connected to the first electrical connections. The first electrical connections in the first arrangement have a greater spatial density than the second electrical connections in the second arrangement.

Applications that extend the basic concept of determining spatial relationships between images and generating a model allowing users to experience the images in a 3D environment are provided. One application is directed to the creation of documents that may be readily shared, viewed, and edited, wherein the documents include references to underlying content comprising a 3D environment and images positioned therein and captures connections between images. Another application relates to ranking images based on user viewing information, such as the number of users who have viewed an image and how long an image was viewed. Yet another application is directed to analyzing the spatial density of images within a 3D environment to determine points of user interest. A further application relates to using spatially indexed images to navigate between webpages and 3D environments.

High temperature plasma raw material is added drop-wise, for example, and evaporated by irradiation with a laser beam. The laser beam passes through a discharge area between a pair of electrodes and irradiates the high temperature plasma raw material. Pulsed power is applied to the space between the electrodes in such a way that discharge current reaches a specified threshold value at a time when at least part of the evaporated material reaches the discharge channel. As a result, discharge starts between the electrodes, plasma is heated and excited and then EUV radiation is generated. The EUV radiation thus generated passes through a foil trap, is collected by EUV radiation collector optics and then extracted. The irradiation of the laser beam allows setting of the space density of the high temperature plasma raw material to a specified distribution and defining of the position of a discharge channel.

Field Image Tomography (FIT) is a fundamental new theory for determining the three-dimensional (3D) spatial density distribution of field emitting sources. The field can be the intensity of any type of field including (i) Radio Frequency (RF) waves in Magnetic Resonance Imaging (MRI), (ii) Gamma radiation in SPECT / PET, and (iii) gravitational field of earth, moon, etc. FIT exploits the property that field intensity decreases with increasing radial distance from the field source and the field intensity distribution measured in an extended 3D volume space can be used to determine the 3D spatial density distribution of the emitting source elements. A method and apparatus are disclosed for MRI of target objects based on FIT. Spinning atomic nuclei of a target object in a magnetic field are excited by beaming a suitable Radio Frequency (RF) pulse. These excited nuclei emit RF radiation while returning to their normal state. The intensity or amplitude distribution of the RF emission field g is measured in a 3D volume space that may extend substantially along the radial direction around the emission source. g is related to the 3D tomography f through a system matrix H that depends on the MRI apparatus, and noise n through the vector equation g=Hf+n. This equation is solved to obtain the tomographic image f of the target object by a method that reduces the effect of noise.

A double-gate semiconductor device provides a high breakdown voltage allowing for a large excursion of the output voltage that is useful for power applications. The double-gate semiconductor device may be considered a double-gate device including a MOS gate and a junction gate, in which the bias of the junction gate may be a function of the gate voltage of the MOS gate. The breakdown voltage of the double-gate semiconductor device is the sum of the breakdown voltages of the MOS gate and the junction gate. Because an individual junction gate has an intrinsically high breakdown voltage, the breakdown voltage of the double-gate semiconductor device is greater than the breakdown voltage of an individual MOS gate. The double-gate semiconductor device provides improved RF capability in addition to operability at higher power levels as compared to conventional transistor devices. The double-gate semiconductor device may also be fabricated in a higher spatial density configuration such that a common implantation between the MOS gate and the junction gate is eliminated.

A method is herein presented to statistically combine multiple seismic attributes for generating a map of the spatial density of fractures. According to an embodiment a first step involves interpreting the formation of interest in 3D seismic volume first to create its time structure map. The second step is creating depth structure of the formation of interest from its time structure map. In this application geostatistical methods have been used for depth conversional, although other methods could be used instead. The third step is extraction of a number of attributes, such as phase, frequency and amplitudes, from the time structure map. The next step is to project the fracture density onto the top of the target formation. The final step is to combine these attributes using a statistical method known as Multi-variant non-linear regression to predict fracture density.
