    摘要: A stepper is combined with hardware that deposits a layer of material in the course of forming an integrated circuit, thus performing the deposition, patterning and cleaning without exposing the wafer to a transfer between tools and combining the function of three tools in a composite tool. The pattern-defining material is removed by the application of UV light through the mask of the stepper, thereby eliminating the bake and development steps of the prior art method. Similarly, a flood exposure of UV eliminates the cleaning steps of the prior art method.

    摘要: Semiconductor structures, such as, for example, field effect transistors (FETs) and/or metal-oxide-semiconductor capacitor (MOSCAPs), are provided in which the workfunction of a conductive electrode stack is changed by introducing metal impurities into a metal-containing material layer which, together with a conductive electrode, is present in the electrode stack. The choice of metal impurities depends on whether the electrode is to have an n-type workfunction or a p-type workfunction. The present invention also provides a method of fabricating such semiconductor structures. The introduction of metal impurities can be achieved by codeposition of a layer containing both a metal-containing material and workfunction altering metal impurities, forming a stack in which a layer of metal impurities is present between layers of a metal-containing material, or by forming a material layer including the metal impurities above and/or below a metal-containing material and then heating the structure so that the metal impurities are introduced into the metal-containing material.

    摘要: A structure, apparatus and method for utilizing vertically interdigitated electrodes serves to increase the capacitor area surface while maintaining a minimal horizontal foot print. Since capacitance is proportional to the surface area the structure enables continual use of current dielectric materials such as Si3N4 at current thicknesses. In a second embodiment of the interdigitated MIMCAP structure the electrodes are formed in a spiral fashion which serves to increase the physical strength of the MIMCAP. Also included is a spiral shaped capacitor electrode which lends itself to modular design by offering a wide range of discrete capacitive values easily specified by the circuit designer.

    摘要: An improved capacitor is formed by a process where an improved node dielectric layer is formed with an improved dielectric constant by performing an Free Radical Enhanced Rapid Thermal Oxidation (FRE RTO) step during formation of the node dielectric layer. Use of an FRE RTO step instead of the conventional furnace oxidation step produces a cleaner oxide with a higher dielectric constant and higher capacitance. Other specific embodiments of the invention include improved node dielectric layer by one or more additional nitridation steps, done by either Remote Plasma Nitridation (RPN), Rapid Thermal Nitridation (RTN), Decoupled Plasma Nitridation (DPN) or other nitridation method; selective oxidation; use of a metal layer rather than a SiN layer as the dielectric base; and selective oxidation of the metal layer.
