The present application provides a semiconductor device, which is provided with a semiconductor element on an upper side of an adhesive layer, the adhesive layer is provided with a tapered portion, a semiconductor unit included in the semiconductor element is provided on an upper side of the adhesive layer, and a first cross-sectional area of the semiconductor unit is greater than a second cross-sectional area of the tapered portion. When the semiconductor device is transferred, the laser only needs to irradiate the tapered portion, so that the area of the required laser spot is reduced, thereby stabilizing the transfer of the semiconductor device and avoiding damage to the semiconductor device.

This utility model discloses a laser triangulation ranging device and system; relating to the field of laser ranging technology; including a laser for emitting laser light towards the object being measured; a light-receiving lens assembly for receiving the reflected laser light from the object being measured and correcting and focusing the reflected laser light spot; the light-receiving lens assembly includes a focusing lens and multiple correction elements; the light spot of the reflected laser light from each correction element is corrected in different properties and falls onto the light-receiving element; this solution improves the structure of the traditional laser triangulation ranging optical path by correcting the light spot of the reflected laser light spot in different properties through the light-receiving lens assembly, ensuring measurement accuracy, reducing costs, and effectively accelerating assembly efficiency; by increasing the light spot size in the laser transmission direction at the position of the light-receiving element through the light-receiving lens assembly, the center of the light spot does not need to be aligned with the center of the light-receiving element to be detected, reducing the structural accuracy of the laser triangulation ranging device and improving assembly efficiency.
