    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 metallization process is provided. The metallization process comprises the following steps. First, a semiconductor base having at least a silicon-containing conductive region is provided. Afterwards, nitrogen ions are implanted into the silicon-containing conductive region. Next, a first thermal process is performed on the semiconductor base for repairing the surface of the semiconductor base. Then, a metal layer is formed on the surface of the semiconductor base and the metal layer covers the silicon-containing conductive region. Lastly, a second thermal process is performed on the semiconductor base covered with the metal layer so as to form a metal silicide layer on the silicon-containing conductive region.

    摘要: A process for forming STI regions comprises performing an In Situ Steam Generation (ISSG) radical conversion on a SiN liner layer within an STI trench in order to expose the top corner of the trench and simultaneously cause rounding the top corner of a liner oxide layer within the trench. The rounding of the liner oxide layer can prevent thinning of a subsequently formed gate oxide.

    摘要: A nitride read only memory comprises a selectively grown, epitaxial, shunt silicon layer (shunt layer) that reduces the bit line sheet resistance and increases bit line mobility. The shunt layer can be grown by a in situ, P-doped deposit at high temperature. A bit line interface without native oxide and excellent electron mobility can be achieved using the methods for selective epitaxial growth described herein.

    摘要: In a method of fabricating a flash memory, a tunneling dielectric layer, a first conductive layer and a mask layer are sequentially formed on a substrate to form a gate structure. Buried source/drain regions are then formed in the substrate between the strips. The strips are further patterned into floating gate structures. An insulation layer is formed sideways adjacent to the gate structure. The insulation layer has a top surface lower than a top surface of the first conductive layer of the gate structure. The mask layer is removed, and an additional conductive layer is formed on the first conductive layer in a manner to extend over the adjacent insulation layer. The first and additional conductive layers form a floating gate. A gate dielectric layer is formed on the floating gate, and a control gate is formed on the gate dielectric layer.

    摘要: A method of forming a semiconductor device is provided. The method includes providing a semiconductor substrate, and forming a first conductive layer over the substrate. In one example, an insulating layer may be formed over the semiconductor substrate, with the first conductive layer being formed over the insulating layer. The method also includes forming an interpoly dielectric layer over the first conductive layer. In this regard, forming the interpoly dielectric layer includes forming a silicon oxide layer, and subjecting the silicon oxide layer to oxide densification to form an oxide-densified silicon oxide layer. And the method includes forming a second conductive layer over the interpoly dielectric layer.
