Abstract: A method for forming a semiconductor device is presented. A substrate prepared with a dielectric layer formed thereon is provided. A sacrificial and a hard mask layer are formed on the dielectric layer. The dielectric, sacrificial and hard mask layers are patterned to form an interconnect opening. The interconnect opening is filled with a conductive material to form an interconnect. The conductive material is processed to produce a top surface of the conductive material that is substantially planar with a top surface of the sacrificial layer. The sacrificial layer is removed. The sacrificial layer protects the dielectric layer during processing of the conductive material.

Abstract: The invention relates to methods of producing jelly confectionery products, and to jelly confectionery products themselves. The centre-filled jelly confectionery comprises—a centre filling, —a casing, and —a backing layer, wherein the backing layer has a different visual appearance compared to the casing. According to one embodiment, the centre filling is coloured, the casing comprises a colouring agent, and the backing layer comprises said colouring agent of the casing, at a concentration that is greater than in the casing. According to another embodiment, the centre filling is coloured, the casing is uncoloured, and the backing layer is coloured.

Abstract: A method of filling gaps in dielectric layers is disclosed. A wafer is provided having a dielectric layer containing gaps to be filled with copper, some of the gaps, denoted deeper gaps, having aspect ratios so large that filling these gaps with copper using ECP could result in pinhole like voids. A blanket conformal metal barrier layer is formed and the wafer is then submerged in a solution to electroless plate a blanket conformal copper seed layer. A partial filling of deeper gaps with copper reduces the effective aspect ratios of the deeper gaps to the extent that ECP could be used to complete the copper filling of the gaps without forming pinhole like voids. ECP is then used to complete the copper filling of the gaps. The wafer is annealed and CMP performed to planarize the surface, giving rise to a structure in which the gaps are filled with copper and are separated by the dielectric layer.
