ABSTRACT

The operating temperature of integrated magnetic components can be critical. Excessively high temperature can significantly modify the properties of components, especially those of magnetic material, such as saturation magnetization and magnetic permeability. This article introduces an experimental characterization method using two different sensors. We compare the results obtained from these sensors. Initially, the method is validated using a "meander component, and subsequently, it is applied to planar spiral inductors, both with and without magnetic material.

ABSTRACT

Optical scatterometry has been given much credit during the past few years in the semiconductor industry. The geometry of an optical diffracted structure is deduced from the scattered intensity by solving an inverse problem. This step always requires a previously defined geometrical model. We develop an artificial neural network classifier whose purpose is to identify the structural geometry of a diffraction grating from its measured ellipsometric signature. This will take place before the characterization stage. Two types of geometry will be treated: sinusoidal and symmetric trapezoidal. Experimental results are performed on two manufactured samples: a sinusoidal photoresist grating deposited on a glass substrate and a trapezoidal grating etched on a SiO2 substrate with periods of 2 microm and 0.565 microm, respectively.

ABSTRACT

El gran tema del Contrato Social es, ni más ni menos, que la fundamentación de la legitimidad democrática. Ciertamente, su temática no se agota ahí, y su estudio no puede ser ajeno al período histórico que la vío nacer, pero su idea-clave es la elaboración del concepto de la sociedad civil, su separación del concepto de Estado y la subordinación de éste a aquélla. La concepción roussoniana parte de reconocer la estructura dualista de la sociedad moderna, en la cual el primado decisorio corresponde al pueblo que forma "el cuerpo soberano". El pacto social de Rousseau no es, ni ha pretendido ser nunca, un a hipótesis histórica es una fundamentación teórica. Que trata de fundamentar en la razón la legitimidad queda claro desde el primer capítulo de la obra. Rosseau declara allí ignorar cómo el hombre perdió la libertad primaria del estado de naturaleza. Para el autor, los hombres ceden mediante el contrato social el derecho ilimitado a todo cuando les apetece. Ganan, en cambio la libertad civil que les hace dueños de sí mismos y les garantiza contra toda dependencia personal. Poque la voluntad general tiende a evitar los intereses particulares en conflicto y armonizarlos. Precisamente la Voluntad General tiene como finalidad socializar todos los intereses.
