Abstract: A method for multi-link operation (MLO) is provided. The method for MLO may be applied to an apparatus. The method for MLO may include the following steps. A multi-chip controller of the apparatus may assign different data to a plurality of chips of the apparatus, wherein each chip corresponds to one link of multi-links. Each chip may determine whether transmission of the assigned data has failed. A first chip of the chips may transmit the assigned data to an access point (AP) in response to the first chip determining that the transmission of the assigned data has not failed.

Abstract: A bonding structure that may be used to form 3D-IC devices is formed using first oblong bonding pads on a first substrate and second oblong bonding pads one a second substrate. The first and second oblong bonding pads are laid crosswise, and the bond is formed. Viewed in a first cross-section, the first bonding pad is wider than the second bonding pad. Viewed in a second cross-section at a right angle to the first, the second bonding pad is wider than the first bonding pad. Making the bonding pads oblong and angling them relative to one another reduces variations in bonding area due to shifts in alignment between the first substrate and the second substrate. The oblong shape in a suitable orientation may also be used to reduce capacitive coupling between one of the bonding pads and nearby wires.

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: An electric contact structure adopted for an LED comprises a nitride middle layer and an N-type metal electrode layer. The LED includes an N-type semiconductor layer, a light emission layer and a P-type semiconductor layer that are stacked to form a sandwich structure. The nitride middle layer is patterned and formed on the N-type semiconductor layer. The N-type metal electrode layer is formed on the nitride middle layer and prevented from being damaged by diffusion of the metal ions as the nitride middle layer serves as a blocking interface, thus electric property of the N-type semiconductor layer can be maintained stable. The nitride middle layer would not be softened and condensed due to long-term high temperature, thereby is enhanced adhesion. Moreover, the N-type metal electrode layer further can be prevented from peeling off, hence is increased the lifespan of the LED.

Abstract: A reflection curved mirror structure is applied to a vertical light-emitting diode (LED) which includes a P-type electrode, a permanent substrate, a binding layer, a buffer layer, a mirror layer, a P-type semiconductor layer, a light-emitting layer, an N-type semiconductor layer and an N-type electrode that are stacked in sequence. Between the P-type semiconductor layer and the mirror layer is a filler. The filler is located right below the N-type electrode to form a protruding curved surface facing the light-emitting layer. The mirror layer forms a mirror structure along the protruding curved surface. With reflection provided by the mirror structure, excited light from the light-emitting layer is reflected towards two sides, so that the excited light can dodge the N-type electrode without being shielded to increase light extraction efficiency.
