    摘要: The present invention intends to provide a semiconductor device capable of realizing a thin gate stack and the manufacturing method thereof. A gate cap layer and/or a protection insulating film (an etching stopper) has a plurality of insulating materials such as oxide and nitride stacked on each other. With this structure, an insulating layer having an etching rate lower than that of the interlayer insulating layer, for example, can be exposed during the etching of the interlayer insulating layer, and the gate stack can be formed thin and the aspect ratio of the contact hole formed in the device can be reduced. The present invention can realize a thin gate stack in such a manner, and thus is suitable for a SAC used in a DRAM.

    摘要: Disclosed is a wiring structure and method of forming the structure with a conductive diffusion barrier layer having a thick upper portion and thin lower portion. The thicker upper portion is located at the junction between the wiring structure and the adjacent dielectric materials. The thicker upper portion: (1) minimizes metal ion diffusion and, thereby TDDB; (2) allows a wire width to dielectric space width ratio that is optimal for low TDDB to be achieved at the top of the wiring structure; and (3) provides a greater surface area for via landing. The thinner lower portion: (1) allows a different wire width to dielectric space width ratio to be maintained in the rest of the wiring structure in order to balance other competing factors; (2) allows a larger cross-section of wire to reduce current density and, thereby reduce EM; and (3) avoids an increase in wiring structure resistivity.
