Description

technical field [0001] The invention belongs to the field of integrated manufacturing of microelectronic systems, and relates to a multipurpose integrated structure of inductance and capacitance. Background technique [0002] In the past few decades, with the continuous advancement of information technology, electronic products have continued to develop in the direction of miniaturization and integration. System integration is an inevitable trend in the development of microelectronics. When integrated circuit chips follow Moore's law to develop toward higher integration and smaller line widths, off-chip discrete passive devices such as inductors and capacitors still occupy a large proportion of space in electronic systems. In order to further reduce the space occupied by the system and increase the degree of integration, it is necessary to realize the miniaturization and integration of off-chip discrete devices. As an important component of electronic circuits, the miniatur...
