摘要： Cu interconnects are formed with composite capping layers for reduced electromigration, improved adhesion between Cu and the capping layer, and reduced charge loss in associated non-volatile transistors. Embodiments include depositing a first relatively thin silicon nitride layer having a relatively high concentration of Si—H bonds on the upper surface of a layer of Cu for improved adhesion and reduced electromigration, and depositing a second relatively thick silicon nitride layer having a relatively low concentration of Si—H bonds on the first silicon nitride layer for reduced charge loss.

摘要： The present invention facilitates dual bit memory devices and operation of dual bit memory device by providing systems and methods that employ a relatively thin undoped TEOS liner during fabrication, instead of a relatively thick TEOS layer that is conventionally used. Employment of the relatively thin liner facilitates dual bit memory device operation by mitigating charge loss and contact resistance while providing protection against unwanted dopant diffusion. The present invention includes utilizing a relatively thin undoped TEOS liner that is formed on wordlines and portions of a charge trapping dielectric layer. The relatively thin undoped TEOS liner is formed with a thickness of less than about 400 Angstroms so that contact resistance and charge loss are improved and yet providing suitable protection for operation of the device. Additionally, the present invention includes foregoing with an undoped TEOS liner altogether.

摘要： A method for making 0.25-micron semiconductor chips includes annealing the metal interconnect lines prior to depositing an inter-layer dielectric (ILD) between the lines. During annealing, an alloy of aluminum and titanium forms, which subsequently volumetrically contracts, with the contraction being absorbed by the aluminum. Because the alloy is reacted prior to ILD deposition, however, the aluminum is not constrained by the ILD when it attempts to absorb the contraction of the alloy. Consequently, the likelihood of undesirable void formation. in the interconnect lines is reduced. The likelihood of undesirable void formation is still further reduced during the subsequent ILD gapfill deposition process by using relatively low bias power to reduce vapor deposition temperature. and by using relatively low source gas deposition flow rates to reduce flow-induced compressive stress on the interconnect lines during ILD formation.

摘要翻译： 制造0.25微米半导体芯片的方法包括在线之间沉积层间电介质（ILD）之前退火金属互连线。 在退火期间，形成铝和钛的合金，其随后容积收缩，铝的收缩被铝吸收。 因为合金在ILD沉积之前反应，所以当铝试图吸收合金的收缩时，铝不受ILD的约束。 因此，形成不希望的空隙的可能性。 在互连线路中减少。 在随后的ILD间隙填充沉积过程中，通过使用相对低的偏压功率来降低气相沉积温度，仍然进一步降低了不希望的空隙形成的可能性。 并且通过使用相对低的源气体沉积流速来减少在ILD形成期间在互连线上的流动引起的压缩应力。
