Latest Patents

One of his latest patents is titled "Nozzle having real time inspection functions." This invention describes a method of manufacturing a semiconductor device that involves receiving a workpiece and using a nozzle to dispense fluid toward its surface. The nozzle is designed with a first and second channel to facilitate fluid flow. A light source emits light from within the nozzle toward the surface while dispensing the fluid. A light sensor, also located within the nozzle, receives the reflected light from the surface, allowing for the examination of the reflected light's status. The emitted and reflected light propagate parallel to the longitudinal axis of the channels. Another patent under the same title focuses on monitoring fluid applied from the nozzle to a wafer's surface. It involves emitting light from the nozzle, receiving reflected light, and determining any variations in the fluid based on the reflected light.
