Abstract
Aspects generally relate to forming components in an area inside a guard ring structure in an integrated circuit.
Claims28
An integrated circuit comprising:
- a guard ring formed in a first area of the integrated circuit using several metal layers, the guard ring at least partially surrounding a component in a second area of the integrated circuit;
- a metal-oxide-metal (MOM) capacitor structure formed in a plurality of metal layers inside the first area.
An integrated circuit comprising:
- a guard ring formed using several metal layers;
- a metal resistor structure formed in a plurality of metal layers inside the guard ring.
A method comprising:
- forming a guard ring in a first area of an integrated circuit, the guard ring formed using several metal layers, the guard ring at least partially surrounding a component in a second area of the integrated circuit;
- and
- forming a metal-oxide-metal (MOM) capacitor structure in a plurality of metal layers in the first area.
A method comprising:
