Abstract: A display panel including a circuit board, a plurality of bonding pads, a plurality of light emitting devices, and a plurality of solder patterns is provided. The bonding pads are disposed on the circuit board, and each includes a first metal layer and a second metal layer. The second metal layer is located between the first metal layer and the circuit board. The first metal layer includes an opening overlapping the second metal layer. A material of the first metal layer is different from a material of the second metal layer. The light emitting devices are electrically bonded to the bonding pads. Each of the solder patterns electrically connects one of the light emitting devices and one of the bonding pads. The solder patterns each contact the second metal layer through the opening of the first metal layer of one of the bonding pads to form a eutectic bonding.

Abstract: A gate structure is provided. The gate structure includes a substrate, a gate disposed on the substrate and a gate dielectric layer disposed between the substrate and the gate, wherein the gate dielectric layer is in the shape of a barbell. The barbell has a thin center connecting to two bulging ends. Part of the bulging ends extends into the gate and the substrate.

Abstract: A non-volatile memory structure includes a substrate, a gate electrode formed on the substrate, conductive spacers respectively formed on two sides of the gate electrode, and an oxide-nitride-oxide (ONO) structure having an inverted T shape formed on the substrate. The gate electrode includes a gate conductive layer and a gate dielectric layer. The ONO structure includes a base portion and a body portion. The base portion of the ONO structure is sandwiched between the gate electrode and the substrate, and between the conductive spacer and the substrate. The body portion of the T-shaped ONO structure is upwardly extended from the base portion and sandwiched between the gate electrode and the conductive spacer.
