摘要: The invention provides a method of calculating an equivalent circuit, which reduces the number of elements constituting a network to a large extent with a target accuracy secured. The method of the invention calculates an equivalent circuit by a computer, with regard to an object that has a conductor, a dielectric to support the conductor, and plural input/output terminals to the outside. Step 1 in the method receives inputs of geometry information to specify a shape of a conductor in a circuit board being the object of determining the equivalent circuit, and material information to specify a material of the circuit board; Step 2 partitions the shape of the objective conductor into meshes on the basis of the geometry information received, and creates mesh data to be expressed; Step 3 calculates a nodal admittance matrix from the mesh data, and stores the result; step 4 calculates the number of nodes and the number of independent networks on the basis of the mesh data, determines an incidence matrix, and determines the structure of an equivalent network by means of the calculated nodal admittance matrix and incidence matrix; and Step 5 determines the values of elements of the equivalent network.

摘要: A semiconductor power conversion device includes two bridge-connected semiconductor switches, an output terminal, and first and second pairs of positive and negative direct current terminals. First conductors connect the negative direct current terminals of the first and second pairs with the output terminal through one of the two bridge-connected semiconductor switches, while second conductors connect the positive direct current terminals of the first and second pairs with the other of the two bridge-connected semiconductor switches. A housing is provided, which includes the two bridge-connected semiconductor switches, and at least a portion of the first conductor and of the second conductor as a multilayer structure formed by sandwiching an insulator between the first and second conductors inside the housing. The first and second pairs of direct current terminals are arranged on one side of one plane of the housing.

摘要: A plasma processing apparatus and a method therefor which can achieve a preferred process rate, a fine pattern process capability, a selectivity and uniformity of processing at the same time compatibly for a large size wafer, which effects are achieved by controlling the plasma state and the dissociation state of etching gas through control of the electron resonance through application of a magnetic field thereto. A high frequency power at 20-300 MHz is applied across a pair of electrodes in a vacuum process chamber, and a magnetic field is formed parallel to the plane of the electrodes in the space between the electrodes. By controlling the intensity of the magnetic field in a range of 100 gauss or smaller, formation of electron cyclotron resonance and electron sheath resonance occurring from interaction between the electrical field and the magnetic field in the electrode sheath portion is controlled. Thereby, the plasma state, i.e., the electron density, electron energy distribution and dissociation state of the process gas in the plasma, can be controlled. The magnetic field is generated by a plurality of coils, an outer shield, and pendant yoke to form magnetic field parallel to the plane of the electrodes in the space between the upper and the bottom electrodes.
