Abstract: A light emission apparatus includes a laser diode configured to emit a light; a laser driver electrically coupled to the laser diode, the laser driver being configured to drive the laser diode to generate the light; and an optical module arranged to receive the light emitted by the laser diode, the optical module comprising at least one optical element and being configured to adjust the light and emits a transmitting light; wherein the transmitting light emits from the optical module with an illumination angle and the optical module adjusts the light to vary the illumination angle.

Abstract: The present disclosure is directed to methods and devices for devices including multiple die. A wafer is received having a plurality of die and a plurality of scribe lines. A dicing process is performed on the wafer. The dicing process includes identifying a first scribe line of the plurality of scribe lines, the first scribe line interposing a first die and a second die of the plurality of die; and performing a partial cut on the first scribe line. In embodiments, other scribe lines of the wafer are, during the dicing process, fully cut. After the dicing, the first die and the second die are mounted on a substrate such as an interposer. The first die and the second die are connected by a portion of the first scribe line, e.g., remaining from the partial cut, during the mounting.

Abstract: An integrated circuit package includes an interposer, the interposer including: a first redistribution layer, a second redistribution layer over the first redistribution layer in a central region of the interposer, a dielectric layer over the first redistribution layer in a periphery of the interposer, the dielectric layer surrounding the second redistribution layer in a top-down view, a third redistribution layer over the second redistribution layer and the dielectric layer, and a first direct via extending through the dielectric layer. A conductive feature of the third redistribution layer is coupled to a conductive feature of the first redistribution layer through the first direct via.

Abstract: A rack structure for a rack assembly includes: a base shaft including a first end surface, an opposite second end surface, an inserting recess recessed from the first end surface to the second end surface, an connecting surface located between the first and second end surfaces, and at least three connecting portions which are mounted on the connecting surface and inclined from the first end surface to the second end surface; and at least three connecting arms each including: a jointing portion formed at one end thereof and to be connected to the connecting potion, a support portion formed at another end opposite the jointing portion, and a plurality of hanging holes defined between the jointing portion and the support portion, wherein an extension plane of the second end surface is located between the support portion and the first end surface.
