  • Publication number: 20230369241
    Abstract: A semiconductor device is formed by providing a semiconductor package including a shielding layer and forming a slot in the shielding layer using a laser. The laser is turned on and exposed to the shielding layer with a center of the laser disposed over a first point of the shielding layer. The laser is moved in a loop while the laser remains on and exposed to the shielding layer. Exposure of the laser to the shielding layer is stopped when the center of the laser is disposed over a second point of the shielding layer. A distance between the first point and the second point is approximately equal to a radius of the laser.
