Integrated circuit structure

An IC structure comprising:

• a substrate comprising a memory region and a logic region;
• a first material layer over the substrate, the first material layer comprising a first portion over the memory region and a second portion over the logic region;
• a second material layer covering the first portion of the first material layer and not covering the second portion of the first material layer;
• a via structure extending through the first material layer and the second material layer;
• and
• a memory cell structure over the via structure.

An IC structure comprising:

• a substrate comprising a memory region and a logic region;
• a first material layer having a first portion over the memory region and a second portion over the logic region;
• a second material layer over the first portion of the first material layer, the second portion of the first material layer extending beyond an edge of the second material layer;
• a via structure extending through the first material layer and the second material layer;
• and
• a memory cell structure over the via structure.
