Abstract: Generally discussed herein are systems and methods that can include a stretchable and bendable device. According to an example a method can include (1) depositing a first elastomer material on a panel, (2) laminating trace material on the elastomer material, (3) processing the trace material to pattern the trace material into one or more traces and one or more bond pads, (4) attaching a die to the one or more bond pads, or (5) depositing a second elastomer material on and around the one or more traces, the bonds pads, and the die to encapsulate the one or more traces and the one or more bond pads in the first and second elastomer materials.

Abstract: The present subject matter relates to the field of fabricating microelectronic devices. In at least one embodiment, the present subject matter relates to forming an interconnect that has a portion thereof which becomes debonded from the microelectronic device during cooling after attachment to an external device. The debonded portion allows the interconnect to flex and absorb stress.

Abstract: Interconnect structures including a selective via post disposed on a top surface of a lower level interconnect feature, and fabrication techniques to selectively form such a post. Following embodiments herein, a minimum interconnect line spacing may be maintained independent of registration error in a via opening. In embodiments, a selective via post has a bottom lateral dimension smaller than that of a via opening within which the post is disposed. Formation of a conductive via post may be preferential to a top surface of the lower interconnect feature exposed by the via opening. A subsequently deposited dielectric material backfills portions of a via opening extending beyond the interconnect feature where no conductive via post was formed. An upper level interconnect feature is landed on the selective via post to electrically interconnect with the lower level feature.

Abstract: A chemical composition and methods to remove defects while maintaining corrosion protection of conductors on a substrate are described. The composition includes a conductive solution, a corrosion inhibitor; and a surfactant. A surfactant-to-inhibitor ratio in the composition is a function of a metal. The surfactant is an anionic surfactant, a non-ionic surfactant, or any combination thereof. The concentration of the corrosion inhibitor in the chemical composition can be low. The corrosion inhibitor can form soft bonds with a conductor material. The conductive solution can be a high ionic strength solution. The composition is applied to a wafer having conductors on a substrate. At least two conductors on the substrate have different potentials. The composition can be used to clean the wafer after forming the conductors on the substrate. The composition can be used for chemical mechanical polishing of the wafer.

Abstract: A method for reducing the dissolution of aluminum gate electrodes in a high pH clean chemistry comprises modifying the high pH clean chemistry to include a silanol-based chemical. The silanol-based chemical causes a protective layer to form on a top surface of the aluminum gate electrode. The protective layer substantially reduces or prevents corrosion that occurs due to the high pH level of the clean chemistry. The protective layer is formed by the silanol-based chemical bonding to the aluminum gate electrode through a hydrolysis reaction, thereby forming a silanol-based protective layer.

Abstract: The present application discloses process comprising providing a wafer, the wafer comprising an inter-layer dielectric (ILD) having a feature therein, an under-layer deposited on the ILD, and a barrier layer deposited on the under-layer, and a conductive layer deposited in the feature, placing the wafer in an electrolyte, such that at least the barrier layer is immersed in the electrolyte, and applying an electrical potential between the electrode and the wafer.
