Semiconductor circuit apparatus and method for fabricating the semiconductor circuit apparatus

A monolithically integrated semiconductor circuit apparatus, comprising:

• a semiconductor substrate having a main surface;
• a plurality of circuit elements disposed at least one of on said semiconductor substrate and in said semiconductor substrate, said plurality of circuit elements including at least one completely formed semiconductor memory device having at least one of memory cells and memory cell groups, drive circuits associated with said at least one completely formed semiconductor memory device, and a complete digital logic component monolithically integrated on said semiconductor substrate;
• a plurality of contact-making planes including a first contact-making plane having a first interconnect pattern, a penultimate contact-making plane having a penultimate interconnect pattern with a partial region, and a last contact-making plane having a last interconnect pattern, said first contact-making plane being closer to said main surface of said semiconductor substrate than said penultimate contact-making plane, said penultimate contact-making plane being closer to said main surface of said semiconductor substrate than said last contact-making plane, said first, penultimate, and last interconnect patterns being provided for electrically interconnecting said plurality of circuit elements;
• and
• a protection device formed at least in said partial region of said penultimate interconnect pattern, said protection device including at least one of a fuse and an antifuse and being assigned to a redundancy activation for defective ones of said memory cells and memory cell groups in said semiconductor memory device.
