Patent ID: 10043714

Abstract:
A process of forming an integrated circuit containing elongated contacts which connect to three active areas and/or MOS gates, and elongated contacts which connect to two active areas and/or MOS gates and directly connect to a first level interconnect, using a litho-freeze-litho-etch process for a contact etch mask. A process of forming an integrated circuit containing elongated contacts which connect to three active areas and/or MOS gates, and elongated contacts which connect to two active areas and/or MOS gates and directly connect to a first level interconnect, using a litho-freeze-litho-etch process for a first level interconnect trench etch mask. A process of forming the integrated circuit using a litho-freeze-litho-etch process for a contact etch mask and a litho-freeze-litho-etch process for a first level interconnect trench etch mask.
