Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0034] In order to increase the magnetic flux of the inductor to increase the inductance value while reducing the eddy current, and improve the quality factor Q value and the performance of the inductor coil, it is necessary to prepare a three-dimensional integrated inductor structure, including: a metal frame, in the area surrounded by the metal frame There are a number of side-by-side chip cores, and the two ends of each core are fixed on the opposite sides of the metal frame; in addition, it also includes an inductance coil, which is in a three-dimensional spiral shape and surrounds the metal frame in multiple turns in one direction. on all cores in the area.

[0035] The present invention will be described in detail below in conjunction with specific drawings.

[0036] Such as Figure 1~8b...

Abstract

The invention relates to the technical field of semiconductor manufacturing, in particular to a method for manufacturing a three-dimensional integrated inductor structure. By means of the method, an inductor of a three-dimensional structure can be obtained. By manufacturing an induction coil which is formed by connecting a top metal wire with a bottom metal wire in parallel, passes around the magnet core with the magnet core as the center in one direction and is in a three-dimensional spiral shape, the vortex current can be reduced while the inductance is increased by greatly improving the inductance flux, the value Q of the quality factor is increased, and the performance of the inductance coil is improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing, in particular to a method for preparing a three-dimensionally integrated inductor structure. Background technique [0002] With the advancement of science and technology and the improvement of social informatization, more and more technical fields such as computers and communications use radio frequency technology, which promotes the rapid development of radio frequency technology (RFIC). For high frequency, small power consumption, low The requirements of distorted radio frequency technology make the inductance coil necessary. The inductance coil is wound on the lead frame by wires, and the wires are insulated from each other. The winding can be hollow or contain an iron core, referred to as inductance. The inductance is mainly used It is used to isolate and filter AC signals or form a resonant circuit with capacitors and resistors. The most important indicator for evaluatin...
