A display panel includes a substrate including a display area and a pad area spaced apart from the display area, and an uneven pad disposed on the substrate in the pad area. The uneven pad includes a first conductive layer, a first organic layer disposed on the first conductive layer and having an upper surface having an uneven shape, and a second conductive layer disposed on the first organic layer.

A bonding apparatus includes an ultrasonic oscillator which generates ultrasonic vibration, a stage disposed under the ultrasonic oscillator, and an embossed sheet disposed between the ultrasonic oscillator and the stage. The embossed sheet includes a body and a plurality of protrusions protruding downward from a lower surface of the body which faces the stage.

Contact bumps between a contact pad and a substrate can include a rough surface that can mate with the material of the substrate of which may be flexible. The rough surface can enhance the bonding strength of the contacts, for example, against shear and tension forces, especially for flexible systems such as smart label and may be formed via roller or other methods.

The integrated circuit device includes: a pad that has a shape having a longitudinal direction and a lateral direction; a circuit that overlaps the pad in a plan view, and that is electrically coupled to the pad; a lead-out wiring that is led out from an outer edge on a longitudinal side of the pad along the lateral direction of the pad; and a via group that electrically couples the lead-out wiring and a wiring of the circuit and that does not overlap the pad in the plan view.

A method for manufacturing an electronic component includes positioning a first surface of a first component facing a second surface of a second component in a first state. The first surface has a first pad having a first center. The second surface has a second pad having a second center. At least one of the first or second pads includes a metal member. The method includes melting the metal member and moving the first and second components until the melted metal member contacts both pads, moving at least one of the first or second components in a direction along the first surface, and solidifying the metal member in a second state. A first distance in a direction along the first surface between the first and second centers in the first state is longer than a second distance in the direction between the first and second centers in the second state.

An interconnect structure for a semiconductor device is provided herein. The interconnect structure generally includes a conductive pillar electrically coupled to a conductive contact positioned on a semiconductor die and a trace receiver on a distal end of the pillar. The trace receiver has a body electrically coupled to the distal end, and may include a first leg projecting from a first side of the body away from the distal end and a second leg projecting from a second side of the body away from the distal end, such that the body, the first leg, and the second leg together form a cavity. During assembly of the semiconductor device, the cavity is configured to at least partially surround a portion of a semiconductor trace positioned in an insulated substrate. To form the electrical connection, a solder material may be disposed between the trace receiver and the trace.

A capacitor that includes a substrate having a first main surface and a second main surface that are opposite to each other, and a plurality of trench portions on the first main surface; a dielectric film adjacent the first main surface of the substrate and extending into interiors of the plurality of trench portions; a conductor film on the dielectric film and extending into the interiors of the plurality of trench portions; and a bonding pad electrically connected to the conductor film. In a plan view from a direction normal to the first main surface of the substrate, the plurality of trench portions are arranged in second regions disposed along a second direction and not in first regions disposed along a first direction in which a bonding wire electrically connected to the bonding pad extends.
