  • Formation of microspheres through laser irradiation of a surface
    Patent number: 7700032
    Abstract: A laser ablation process is applied to a semiconductor substrate causing the semiconductor material surface and subsurface to be superheated to the point where material is ablated from the material substrate. Optional subsequent laser pulse(s) liquefy the particles, preferably while suspended in air, and the material surface tension causes the liquefied droplet of semiconductor material to form a sphere. The droplet preferably solidifies in air before reaching the substrate of its origin or another substrate for collection.
