LC tank capable of reducing electromagnetic radiation by itself and manufacturing method thereof

An inductance-capacitance (LC) tank manufacturing method for making an LC tank capable of reducing electromagnetic radiation by itself, comprising the following steps:

• forming a plurality of tank areas including:
• determining the size of a first tank area and the size of a second tank area in accordance with an electromagnetic radiation restraining effect;
• defining the first tank area with a first part of an inductance;
• and
• defining the second tank area with a second part of the inductance in which the second part includes a gap;
• forming a cross-interconnection structure operable to electrically connect the first and second parts of the inductance and distinguish the first tank area from the second tank area;
• and
• forming at least one non-parasitic physical capacitance inside at least one of the plurality of tank areas;
• wherein the area ratio of the first tank area to the second tank area is between 40% and 60%.
