Publication number: 20110270593Abstract: In order to design on-chip interconnect structures in a flexible way, a CAD approach is advocated in three dimensions, describing high frequency effects such as current redistribution due to the skin-effect or eddy currents and the occurrence of slow-wave modes. The electromagnetic environment is described by a scalar electric potential and a magnetic vector potential. These potentials are not uniquely defined, and in order to obtain a consistent discretization scheme, a gauge-transformation field is introduced. The displacement current is taken into account to describe current redistribution and a small-signal analysis solution scheme is proposed based upon existing techniques for static fields in semiconductors. In addition methods and apparatus for refining the mesh used for numerical analysis is described.Type: ApplicationFiled: May 2, 2011Publication date: November 3, 2011Applicant: IMECInventors: Peter Meuris, Wim Schoenmaker, Wim Magnus

Patent number: 7541198Abstract: A method of forming a quantum system comprising computational elements, consisting of an insulated ring of superconductive material, and semi-closed rings, which are used as an interface or input/output facility between the quantum bit and the external world, is disclosed. Faraday induction is used to provide electromagnetic coupling between adjacent computational elements and between the computational elements with interface elements of the quantum system. Therefore the corresponding magnetic flux acts as an information carrier. Ferromagnetic cores are used to improve the magnetic coupling between adjacent elements of the quantum system.Type: GrantFiled: February 28, 2006Date of Patent: June 2, 2009Assignees: Interuniversitair Microelektronica Centrum vzw (IMEC), Katholieke Universiteit LeuvenInventors: Wim Magnus, Christoph Kerner, Wim Schoenmaker

Patent number: 6453275Abstract: A method, i.e. the so-called Cube-Assembling Method (CAM), is disclosed for locally refining a n-dimensional mesh in a predetermined domain, wherein the mesh comprises nodes and n−1 planes connecting these nodes thereby dividing said domain in n-dimensional first elements. By applying a mesh on a domain, the domain can be introduced in a computer aided design environment for optimization purposes. Concerning the mesh, one of the issues is to perform the optimization using the appropriate amount of nodes at the appropriate location The method of the present invention succeeds in adding or removing nodes locally. The assembling is done over the elements, being e.g. squares or cubes or hypercubes dependent of the dimension of the mesh. Like the finite-box method, the CAM method is easy to program, even in higher dimensions. However, the CAM method does not suffer from the restriction that only one line may terminate at the side of a box.Type: GrantFiled: June 9, 1999Date of Patent: September 17, 2002Assignee: Interuniversitair Micro-Elektronica Centrum (IMEC vzw)Inventors: Wim Schoenmaker, Wim Magnus
