    摘要: A method of fabricating a semiconductor device is provided. An interlayer dielectric layer is formed on one or more semiconductor layers (402). One or more feature regions are formed in the interlayer dielectric layer (404). A first conductive layer is formed in at least a portion of the feature regions and on the interlayer dielectric layer (406)). A first anneal is performed that promotes grain growth of the first conductive layer (408). An additional conductive layer is formed on the first conductive layer (410) and an additional anneal is performed (412) that promotes grain growth of the additional conductive layer and further promotes grain size growth of the first conductive layer. Additional conductive layers can be formed and annealed until a sufficient overburden amount has been obtained. Subsequently, a planarization process is performed that removes excess conductive material and thereby forms and isolates conductive features in the semiconductor device (414).

    摘要: A coil (50) is placed adjacent to a semiconductor wafer (10). An AC excitation current is used to create a changing electromagnetic field (60) is the wafer (10). The wafer is heated by a heat source (20) and the conductivity of the wafer (10) will change as a function of the wafer temperature. Induced eddy currents will cause the inductance of the coil (50) to change and the temperature of the wafer (10) can be determined by monitoring the inductance of the coil (50).

    摘要: A method (10) of forming a MIM (metal insulator metal) capacitor is disclosed whereby adverse affects associated with copper diffusion are mitigated even as the capacitor is scaled down. A layer of bottom electrode/copper diffusion barrier material (136) is formed (16) within an aperture (128) wherein the capacitor (100) is to be defined. The bottom electrode layer (136) is formed via a directional process so that a horizontal aspect (138) of the layer (136) is formed over a metal (110) at a bottom of the aperture (128) to a thickness (142) that is greater than a thickness (144) of a sidewall aspect (148) of the layer (136) formed upon sidewalls (132) of the aperture (128). Accordingly, the thinner sidewall aspects (148) are removed during an etching act (18) while some of the thicker horizontal aspect (138) remains. A layer of capacitor dielectric material (150) is then conformally formed (20) into the aperture 128 and over the horizontal aspect (138). A layer of top electrode material (152) is then conformally formed (22) over the layer of capacitor dielectric material (150) to complete the capacitor stack (154).
