Abstract: Methods and semiconductor devices are provided. A method includes determining a location of a polyimide opening (PIO) corresponding to an under-bump metallization (UBM) feature in a die. The die includes a substrate and an interconnect structure over the substrate. The method also includes determining a location of a stacked via structure in the interconnect structure based on the location of the PIO. The method further includes forming, in the interconnect structure, the stacked via structure comprising at most three stacked contact vias at the location of the PIO.

Abstract: A robot for assisting a user in playing golf includes a self-propelled body, a memory device, a processor, a display device, a positioning device, a compass device, a lidar device and a Doppler radar that cooperatively estimate a position at which a golf ball would likely land after a shot, and to display the estimated position on a golf course map for assisting the user to find the golf ball.

Abstract: A wearable augmented reality device for golf play assists a golfer who plays golf with a ball and a club, and includes a camera, a memory, a processor and a display. The camera captures an image of the ball and the club so as to obtain a captured image. The memory stores an image recognition module and an image calculation module. The processor executes the image recognition module so as to recognize the ball and the club in the captured image, to execute the image calculation module so as to determine whether the ball is hit by the club according to a positional relationship between the ball and the club in the captured image, and to calculate flight information of the ball to be displayed by the display when it is determined that the ball is hit by the club.

Abstract: A low-bouncing buffer net includes a net material, a net frame and a buffering material. The net frame is used for supporting the net material. The buffering material is disposed on the net material. The disclosure can reduce the bouncing force generated after a golf ball contacts the net and ensure that the golf ball can be stopped in the target.
