Abstract
A method for manufacturing a semiconductor optical device for a LIDAR sensor system for a vehicle includes (a) forming a plurality of microlens structures at respective first locations on a first major surface of respective first and second semiconductor wafers. The method includes (b) forming a plurality of notch structures at respective second locations on a second major surface of the respective first and second semiconductor wafers, wherein the respective second locations on the second major surface are substantially opposite the respective first locations on the first major surface. The method includes (c) bonding the second major surface of the first semiconductor wafer to the second major surface of the second semiconductor wafer to form a semiconductor wafer pair. The method includes (d) dicing the semiconductor wafer pair to segment the semiconductor wafer pair into a plurality of individual semiconductor optical devices.
