    摘要: A method of manufacturing a MOS transistor begins with the provision of a semiconductor substrate. A gate oxide layer, a polysilicon layer and a silicon nitride layer are sequentially formed over the substrate. Next, the gate oxide layer, the polysilicon layer and the silicon nitride layer are patterned to form a gate structure. Subsequently, spacers are formed covering the sidewalls of the gate oxide layer, the polysilicon layer and the silicon nitride layer. Thereafter, a dielectric layer is formed, and covers the semiconductor substrate, the silicon nitride layer and the spacers. Next, a planarization operation is carried out to remove a portion of the dielectric layer. Planarization continues until the silicon nitride layer is exposed. After that, the silicon nitride layer is removed, exposing the polysilicon layer, and then a glue layer is formed over the dielectric layer and the polysilicon layer. Finally, a conductive layer is formed over the glue layer to complete the fabrication of the MOS transistor.

    摘要: A method of reducing laser mark peeling depends on what sort of layer lies over the laser mark. If a structure formed on the laser mark is a conductive layer, an adhesion layer or a passivation layer, the conductive layer, adhesion layer or passivation layer is removed from the laser mark. If a structure formed on a laser mark is a dielectric layer, the dielectric layer is left on the laser mark. The area removed from the upper layer is equal to or bigger than the area removed from the lower layer in order to avoid contacts between the conductive layers. In addition to being used for a laser mark, the method mentioned above can be also used for a wafer edge and an alignment mark.

    摘要: A method for manufacturing shallow trench isolation regions according to the invention uses a first stop layer and a second stop layer as two polishing stop layers, or a polishing stop layer and an etching stop layer, respectively. By performing chemical mechanical polishing twice, or performing chemical mechanical polishing one time and then etch back, the influence on subsequently formed shallow trench isolation regions caused by different sizes and densities thereof can be greatly alleviated.

    摘要: An adjustable method for making trenches for a semiconductor IC device having eliminated top corners is disclosed. The adjustable method includes forming a masking layer on the surface of the silicon nitride layer covering the device substrate that has openings corresponding to the openings of the trenches formed. Dimension of the masking layer opening is relatively greater than the dimension of the opening of the corresponding trench. An anisotropic etching procedure is then performed against the portions of the device substrate exposed out of the coverage of the masking layer, and the anisotropic etching shapes the trench sidewalls into sloped ones having larger dimension at the opening than at the surface of the filling material inside the trenches. This eliminates the top corners at the edges of the trench opening, charge accumulation and consequent leakage current can thus be prevented.

    摘要: A method for adjusting the trench depth of a substrate has the steps as follows. Forming a patterned covering layer on the substrate, wherein the patterned covering layer defines a wider spacing and a narrower spacing. Forming a wider buffering layer arranged in the wider spacing and a narrower buffering layer arranged in the narrower spacing. The thickness of the narrower buffering layer is thinner than the wider buffering layer. Implementing dry etching process to make the substrate corresponding to the wider and the narrower buffering layers form a plurality of trenches. When etching the wider and the narrower buffering layers, the narrower buffering layer is removed firstly, so that the substrate corresponding to the narrower buffering layer will be etched early than the substrate corresponding to the wider buffering layer.
