    摘要: Semiconductor devices and methods of forming a barrier metal in semiconductor devices are disclosed. A disclosed semiconductor device includes a metal layer on a semiconductor substrate; an interlayer dielectric layer on the metal layer, a hole in the interlayer dielectric layer that exposes a portion of the metal layer; and a barrier metal on inner walls of the hole.

    摘要: We disclose a method of applying a sculptured layer of material on a semiconductor feature surface using ion deposition sputtering, wherein a surface onto which the sculptured layer is applied is protected to resist erosion and contamination by impacting ions of a depositing layer. A first protective layer of material is deposited on a substrate surface using traditional sputtering or ion deposition sputtering, in combination with sufficiently low substrate bias that a surface onto which the layer is applied is not eroded away or contaminated during deposition of the protective layer. Subsequently, a sculptured second layer of material is applied using ion deposition sputtering at an increased substrate bias, to sculpture a shape from a portion of the first protective layer of material and the second layer of depositing material. The method is particularly applicable to the sculpturing of barrier layers, wetting layers, and conductive layers upon semiconductor feature surfaces.

    摘要: Method for removing and/or redistributing material in the trenches and/or vias of integrated circuit interconnect structures by a gas cluster ion beam (GCIB) is described to improve the fabrication process and quality of metal interconnects in an integrated circuit. The process entails opening up an undesired ‘necked in’ region at the entrance to the structure, re-depositing the barrier metal from thicker areas such as the neck or bottom of the structure to the side walls and/or removing some of the excess and undesired material on the bottom of the structure by sputtering. The GCIB process may be applied after the barrier metal deposition and before the copper seed layer/copper electroplating or the process may be applied after the formation of the copper seed layer and before electroplating. The method may extend the usability of the known interconnect deposition technologies to next generation integrated circuits and beyond.

    摘要: In a method for forming a wiring of a semiconductor device using an atomic layer deposition, an insulating interlayer is formed on a substrate. Tantalum amine derivatives represented by a chemical formula Ta(NR1)(NR2R3)3 in which R1, R2 and R3 represent H or C1–C6 alkyl group are introduced onto the insulating interlayer. A portion of the tantalum amine derivatives is chemisorbed on the insulating interlayer. The rest of tantalum amine derivatives non-chemisorbed on the insulating interlayer is removed from the insulating interlayer. A reacting gas is introduced onto the insulating interlayer. A ligand in the tantalum amine derivatives chemisorbed on the insulating interlayer is removed from the tantalum amine derivatives by a chemical reaction between the reacting gas and the ligand to form a solid material including tantalum nitride. The solid material is accumulated on the insulating interlayer through repeating the above processes to form a wiring.

    摘要: The present invention provides a method for forming a metal silicide layer in an active area of the semiconductor device. The method for forming the metal silicide layer includes: forming a source/drain junction area on a silicon substrate; forming an attack protection layer on the source/drain junction area, wherein the attack protection layer is electrically conductive and prevents a silicon substrate attack caused by chlorine (Cl) gas; forming a titanium (Ti) layer over the attack protection layer through a low pressure chemical vapor deposition (LPCVD) process using a source gas of TiCl4; and diffusing the Ti layer into the attack protection layer to thereby form a metal silicide layer.
