    摘要: A method of fabricating complementary metal oxide semiconductor (CMOS) field effect transistors which includes selective doping and full silicidation of a polysilicon material comprising the gate electrode of the transistor. In one embodiment, prior to silicidation, the polysilicon is amorphized. In a further embodiment, siliciding is performed at a low substrate temperature.

    摘要: A method for plating copper conductors on an electronic substrate and devices formed are disclosed. In the method, an electroplating copper bath that is filled with an electroplating solution kept at a temperature between about 0° C. and about 18° C. is first provided. A copper layer on the electronic substrate immersed in the electroplating solution is then plated either in a single step or in a dual-step deposition process. The dual-step deposition process is more suitable for depositing copper conductors in features that have large aspect ratios, such as a via hole in a dual damascene structure having an aspect ratio of diameter/depth of more than ⅓ or as high as 1/10. Various electroplating parameters are utilized to provide a short resistance transient in either the single step deposition or the dual-step deposition process. These parameters include the bath temperature, the bath agitation, the additive concentration in the plating bath, the plating current density utilized, the deposition rate of the copper film and the total thickness of the copper film deposited.

    摘要: A semiconductor structure that includes at least one circuit element of a fuse, a diffusion barrier or a capacitor that is formed by refractory metal-silicon-nitrogen is disclosed. A method for fabricating such semiconductor structure that includes a fuse element, a diffusion barrier, a resistor or a capacitor by a refractory metal-silicon-nitrogen material is further disclosed. A suitable refractory metal-silicon-nitrogen material to be used is TaSiN which provides a wide range of resistivity by changing the ratio of Ta:Si:N. The invention provides the benefit that the various components of diffusion barriers, fuses, capacitors and resistors may be formed by a single deposition process of a TaSiN layer, the various components are then selectively masked and treated by either heat-treating or ion-implantation to vary their resistivity selectively while keeping the other shielded elements at the same resistivity.

    摘要: A method forforming a refractory metal-silicon-nitrogen capacitor in a semiconductor structure and the structure formed are described. In the method, a pre-processed semiconductor substrate is first positioned in a sputtering chamber. Ar gas is then flown into the sputtering chamber to sputter deposit a first refractory metal-silicon-nitrogen layer on the substrate from a refractory metal silicide target, or from two targets of a refractory metal and a silicon. N2 gas is then flown into the sputtering chamber until that the concentration of N2 gas in the chamber is at least 35% to sputter deposit a second refractory metal-silicon-nitrogen layer on top of the first refractory metal-silicon-nitrogen layer. The N2 gas flow is then stopped to sputter deposit a third refractory metal-silicon-nitrogen layer on top of the second refractory metal-silicon-nitrogen layer. The multi-layer stack of the refractory metal-silicon-nitrogen is then photolithographically formed into a capacitor.
