    Abstract: A method of fabricating a shallow trench isolation includes formation of a trench in a substrate. An oxide layer is formed on the substrate to fill the trench. A barrier layer and a coating layer are formed in sequence over the substrate. A first etching step is performed to remove a portion of the coating layer and the oxide layer to at least expose the oxide layer on the mask layer. A second etching step is performed to remove the other portion of the coating layer and the oxide layer until exposing the mask layer. Thus, micro-scratches and defects do not happen and thus the invention prevents the occurrence of bridging effect and short circuits.

    Abstract: A method of forming a via. A substrate having a first conductive layer thereon is provided. An inter-metal dielectric layer is formed over the substrate layer by high density plasma chemical vapor deposition. An etch stop layer is formed on the inter-metal dielectric layer. An oxide layer is formed on the etch stop layer. The oxide layer is defined, so that a shallow opening aligned with the first conductive layer is formed to exposed the inter-metal dielectric layer. The inter-metal dielectric layer is etched away within the shallow opening until the first conductive layer is exposed. The opening is filled with a second conductive layer. The oxide layer is defined by photolithography and etching with a first selectivity, with which the oxide layer has a comparable etching rate to the etch stop layer. The inter-metal dielectric layer is etched with a second selectivity, with which the inter-metal dielectric layer has an etching rate higher than the etch stop layer.

    Abstract: A method for forming a double spacer structure comprising the steps of first providing a semiconductor substrate that has a first gate and a second gate already formed thereon, wherein the gate length of the second gate is greater than the gate length of the first gate. Then, a first insulating layer is formed over the substrate and the gates. Next, a photoresist layer is formed over the first insulating layer above the second gate while exposing the first insulating layer above the first gate. Subsequently, a first etching operation is performed to establish a first spacer structure along the sidewalls of the first gate, and then the photoresist layer is removed leaving the first insulating layer over the second gate. Thereafter, a second insulating layer is formed over the substrate, the first gate and the first insulating layer, and then a second etching operation is performed to establish a second spacer structure along the sidewalls of the second gate. Therefore, a second spacer that has a width greater than the first spacer does is finally obtained.

    Abstract: A method of fabricating a metal-oxide semiconductor (MOS) transistor is provided. This method is devised particularly to reduce the level of degradation to the MOS transistor caused by hot carriers. In the fabrication process, a plasma treatment is applied to the wafer to as to cause the forming of a thin layer of silicon nitride on the wafer which covers the gate and the lightly-doped diffusion (LDD) regions on the source/drain regions of the MOS transistor. This thin layer of silicon nitride acts as a barrier which prevents hot carriers from crossing the gate dielectric layer, such that the degradation of the MOS transistor due to hot carriers crossing the gate dielectric layer can be greatly minimized.
