    摘要: The present invention relates generally to semiconductors, and more specifically to semiconductor memory device structures and an improved fabrication process for making the same. The improved fabrication process allows the self-aligned contacts and local interconnects to the processed simultaneously. The process allows the minimal distance requirement between the self-aligned contacts and the local interconnects to be widened, which makes the patterning of self-aligned contacts and local interconnects easier. The widened minimal distance requirement also allows further memory cell shrinkage. The improved structures of self-aligned contacts and local interconnects also have excellent isolation characteristic.

    摘要: A fabrication method of an electronic device is provided. First, a substrate is provided. Then, a patterned amorphous carbon (α-C) layer is formed on the substrate and exposes part of the substrate. Next, a first α-C layer covering the patterned α-C layer and part of the substrate is formed. Then, part of the substrate and part of the first α-C layer covering part of the substrate are removed, so as to form a patterned substrate and a second α-C layer.

    摘要: A BEOL manufacturing process for forming a via on a semiconductor wafer comprises depositing a portion of a first metal adhesion layer within a patterned via hole, followed by a cooling step. The cooling step is then followed by formation of the remainder of the first metal adhesion layer and formation of a second metal adhesion layer within the patterned via hole. This process of forming the remaining portion of the first metal adhesion layer can be referred to as a load, unload, load (LUL) process. By using a LUL process, thermal processing is minimized, which reduces Al extrusion at the via interfaces.

    摘要: A semiconductor device with an unlanded via having an air gap dielectric layer and a silicon-rich oxide (SRO) inter-metal dielectric (IMD) layer, and a method of making the same are provided. The SRO layer acts as an etch-stop layer to prevent unlanded via penetration completely through the IMD layer. In addition, the SRO has a higher extinction coefficient (k) than conventional high-density plasma (HDP) oxide layers, thereby preventing plasma etch damage and excessive void formation in an unlanded via.
