A method for producing a layout of a device in an integrated circuit before actually fabricated is provided. The method includes inputting at least one fixed parameter for the device for fabrication. And then, a first part of a set of variable parameters of a layout of the device is input. The complete set of the variable parameters is generated. It is checked whether or not the layout with the parameters is satisfying a requirement, wherein an end step is reached if the layout is accepted by the requirement, and a new part of the set of variable parameters as the first part being looping in the foregoing steps if the layout is not accepted by the requirement.

Method for producing layout of semiconductor integrated circuit with radio frequency devices

An inductor formed on a semiconductor substrate is provided in the present invention. The inductor comprises a metal layer and an insulator layer. The metal layer constitutes the coil of the inductor. The insulator layer comprises at least one insulator slot, and each insulator slot is encompassed in the metal layer.

Inductor formed on semiconductor substrate

An inductor structure comprising a substrate; a plurality of insulation layers on the substrate; a first spiral electric conductive coil positioned in the insulation layers to form an inductor having a first direction of magnetic field; a second spiral electric conductive coil positioned in the insulation layers to form an inductor having a second direction of magnetic field, in which, the two or more inductors are independently positioned in a same 3-D space and have a good integration.

Inductor structure

A high coupling factor transformer and a manufacturing method thereof are provided. The transformer includes a primary winding and a secondary winding. The secondary winding is adjacent to the primary winding. The secondary winding and the primary winding induct with each other. The primary winding includes a plurality of first protruding portions, and the secondary winding includes a plurality of second protruding portions. The first protruding portions stretch to the secondary winding without electro-contact, and the second protruding portions stretch to the primary winding without electro-contact.
