Patent ID: 6924225

Claim:
A method for producing an electrically conductive contact for at least one contact connection region of an integrated component, the method comprising: providing a semiconductor body with an integrated component disposed thereon and a contact connection area adjacent the integrated component; conformally depositing an insulating material to form a liner over the integrated component; depositing a sacrificial layer over the insulating material of the liner; planarizing the sacrificial layer to uncover a surface of the liner over the integrated component; forming a mask over the sacrificial layer; anisotropically etching the sacrificial layer selectively with respect to the mask, the integrated component and the liner, so that the sacrificial layer at least partially covers the at least one contact connection region in a partial region masked from the etching operation by the mask; depositing a dielectric layer to form an interlevel insulator; removing portions of the interlevel insulator to at least partial uncover the sacrificial layer in the at least one partial region; stripping-out the sacrificial layer selectively with respect to the dielectric layer; stripping-out the insulating material forming the liner; depositing at least one conductive layer to fill the at least first partial region such that an electrically conductive contact is formed.
