    摘要: The present disclosure is related to semiconductor technologies and discloses a semiconductor device and its method of making. In the present disclosure, a transistor's source and drain are led out by forming vias or contact holes in an insulator layer covering the transistor and at metal silicide contact regions corresponding to the source and drain, and by filling the vias with metal-semiconductor compound. Because the metal-semiconductor compound has relatively low resistivity, the resistance of the material in the vias can be minimized. Also, because the material used to fill the vias and the material forming the source/drain contact regions are both metal-semiconductor compound, contact resistance between the material filling the vias and the source/drain contact regions can be minimized. Furthermore, because the material filling the vias is metal-semiconductor compound, the conducting material in the vias and dielectric material in the insulator layer can form good interface and have good adhesion properties, and the conducting material would not cause structural damage in the dielectric material. Thus, there is no need to form a barrier layer between the insulator layer and the material filling the vias.

    摘要: This non-volatile semiconductor memory device includes a memory cell array including NAND cell units formed in a first direction vertical to a surface of a semiconductor substrate. A local source line is electrically coupled to one end of the NAND cell unit formed on the surface of the substrate. The memory cell array includes: a laminated body where plural conductive films, which are to be control gate lines of memory cells or selection gate lines of selection transistors, are laminated sandwiching interlayer insulating films; a semiconductor layer that extends in the first direction; and an electric charge accumulating layer sandwiched between: the semiconductor layer and the conductive film. The local source line includes a silicide layer. The electric charge accumulating layer is continuously formed from the memory cell array to cover a peripheral area of the silicide layer.

    摘要: One method disclosed herein includes, among other things, a method of forming a contact structure to a source/drain region of a transistor device. The transistor device includes a gate structure and a gate cap layer positioned above the gate structure. The method includes forming an extended-height epi contact structure that is conductively coupled to the source/drain region. The extended-height epi contact structure includes an upper surface that is positioned at a height level that is above a height level of an upper surface of the gate cap layer. The method further includes performing an etching process to trim at least a lateral width of a portion of the extended-height epi contact structure, and, after performing the etching process, forming a metal silicide material on at least a portion of the trimmed extended-height epi contact structure and forming a conductive contact on the metal silicide material.
