A memory structure including a storage transistor having a data storage storage region, a gate terminal, a first drain or source terminal, and a second drain or source terminal, the storage transistor being configurable to have a threshold voltage that is representative of data stored in the data storage region; a word line electrically connected to the gate terminal, configured to provide a control voltage during a read operation; a bit line electrically connecting the first drain or source terminal to data detection circuitry; and a source line electrically connected to the second drain or source terminal, configured to provide a capacitance sufficient to sustain at least a predetermined voltage difference between the second drain or source terminal and the gate terminal during the read operation.

A method includes: providing a passivation layer with an embedded MIM capacitor; forming a redistribution layer (RDL) above the passivation layer; and forming an opening in the RDL above the MIM capacitor, wherein the opening separates the RDL into first and second RDL structures, wherein each of the first and second RDL structures has a convex-shaped profile on a sidewall that defines the opening that separates the first RDL structure from the second RDL structure, and wherein the convex-shaped profile on the sidewalls resists stress migration from the RDL to the MIM capacitor to resist stress migration induced cracks forming in the MIM capacitor. The forming an opening includes: removing a portion of the RDL to a first depth using first etching operations; and removing a portion of the RDL to a second depth by laterally etching sidewalls of the first and second RDL structures.

A method for performing an inline detection and repair of a defect on a substrate or interposer that does not destroy the substrate or interposer. The method is performed in the manufacturing area in separate platforms or a single platform. In some embodiments, the method may include detecting a defect on a panel in line to a panel level packaging process using an electron beam to image at least a portion of a surface of the panel, identifying a type of the defect, and repairing the defect on the panel based on the type of the defect in line with the panel level packaging process using a material removal process to remove material to fix a defect or using the electron beam in conjunction with a precursor gas to deposit material to fix a defect. The material removal process may include a plasma beam or an ion beam.

A method for manufacturing an interconnect structure includes: forming a base structure; forming a first metal feature on the base structure, the first metal feature having a first volume and including a first metallic material; forming a first dielectric layer surrounding the first metal feature and over the base structure; and forming a second metal feature in the first dielectric layer, the second metal feature being spaced apart from the first metal feature, having a second volume greater than the first volume, and including a second metallic material different from the first metallic material.
