Abstract: The present disclosure relates to integrated circuit device manufacturing processes. A self-aligned double patterning method is provided. In the method, a lithography process for line cut that determines the locations of line termini is performed after forming a spacer layer alongside the mandrel and prior to stripping the mandrel. The lithographic mask for the line cut is aligned to the mandrel and the spacer layer using a mark made of the mandrel material and the spacer material. Compared to the previous approach where the line cut process is performed after the mandrel removal, in the disclosed approach, the line termini mask is made of the mandrel material and the spacer material, and is more distinguishable compared to a mark made of just the spacer material. Thereby, the methods provide robust photo alignment signal for the line cut photolithography and precise positioning of the line termini mask.

Abstract: A method comprises following steps. A first mandrel is formed over a target layer over a substrate, wherein the first mandrel comprises a mandrel island and a first mandrel strip, the mandrel island comprises a first sidewall and a second sidewall perpendicular to the first sidewall, and the first mandrel strip extends from the first sidewall of the mandrel island. A first spacer is formed along the first and second sidewalls of the mandrel island and a sidewall of the first mandrel strip. The first mandrel is removed from the target layer. The target layer is patterned when the first spacer remains over the target layer.

Abstract: Decoupling metal-insulator-metal (MIM) capacitor designs for interposers and methods of manufacture thereof are disclosed.

Abstract: Embodiments of MIM capacitors may be embedded into a thick IMD layer with enough thickness (e.g., 10 K?˜30 K?) to get high capacitance, which may be on top of a thinner IMD layer. MIM capacitors may be formed among three adjacent metal layers which have two thick IMD layers separating the three adjacent metal layers. Materials such as TaN or TiN are used as bottom/top electrodes & Cu barrier. The metal layer above the thick IMD layer may act as the top electrode connection. The metal layer under the thick IMD layer may act as the bottom electrode connection. The capacitor may be of different shapes such as cylindrical shape, or a concave shape. Many kinds of materials (Si3N4, ZrO2, HfO2, BST . . . etc.) can be used as the dielectric material. The MIM capacitors are formed by one or two extra masks while forming other non-capacitor logic of the circuit.
