摘要： A method is provided for forming separated spacer structures in a mixed-mode integrated circuit, which can be used to form spacer structures with different widths for the various kinds of devices in the mixed-mode integrated circuit. The method is for use on a semiconductor substrate which is formed with at least a first gate for a first kind of device of the mixed-mode integrated circuit and a second gate for a second kind of device of the integrated circuit, with the second gate being larger in width than the first gate such that the first gate is formed with a first spacer structure on the sidewalls thereof to a first desired width while the second gate is formed with a second spacer structure on the sidewalls thereof to a second desired width larger than the first desired width. The method features a two-step etching process in which the first etching process is performed to form one spacer structure to the first desired width, while the second etching process is performed to form the other spacer structure to the second desired width.

摘要： A process of fabricating a read only memory device (ROM) wherein the buried N+lines have desirable well defined very narrow widths and are closely spaced. In the process, an insulating layer is deposited on the substrate. Openings for the buried N+lines having vertical sidewalls are formed through the insulating layer. Spacer layers are formed on the vertical sidewalls of the openings. Impurities are implanted through the openings. The insulating layers is removed and the substrate is oxidized to form silicon oxide insulation strips over the buried N+implanted regions. Next, the read only memory (ROM) device is completed by fabricating floating gates and overlying control gates between the buried N+lines interconnected by a conductive lines that are orthogonal to the buried N+buried lines.

摘要： A method of metallization using a tungsten plug is described. A contact hole is opened to the semiconductor substrate through an insulating layer covering semiconductor structures in and on the semiconductor substrate. A glue layer is deposited conformally over the surface of the insulating layer and within the contact opening. A tungsten plug is formed within the contact opening. The glue layer is removed except for portions of the glue layer underneath the tungsten plug and on the lower sides of the tungsten plug. Ditches are left on the upper sides of the tungsten plug where the glue layer has been removed. The ditches around the tungsten plug are filled with a dielectric material. A second metallization is deposited and patterned. The patterned second metallization does not extend over one side portion of the tungsten plug; that is, there is no dog-bone formation. There is no junction damage through the side portion of the tungsten plug not covered by the second metallization because the dielectric material filling the ditches protects the glue layer from being etched away. In a second embodiment of the invention, after the contact hole is opened, the insulating layer is reflowed forming an overhang around the contact hole. A glue layer is deposited conformally over the surface of the insulating layer and within the contact opening. A tungsten plug is formed within the contact opening.
