Title: The Innovations of Mandar Paranjape
Introduction
Mandar Paranjape is an accomplished inventor based in Cupertino, CA. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to defect inspection and laser power modulation.
Latest Patents
One of Mandar's latest patents is titled "Large-particle monitoring with laser power control for defect inspection." This invention involves inspecting a semiconductor wafer using a main laser beam and a secondary laser beam. The secondary laser beam leads the main laser beam and operates at a lower power. By utilizing the secondary laser beam, particles on the semiconductor wafer that meet a specific size threshold can be detected. Upon detection, the power of both the main and secondary laser beams is reduced, allowing the particle to pass through the main laser beam safely. After the particle has passed, the power levels are restored in a controlled manner.
Another notable patent is "Laser closed power loop with an acousto-optic modulator for power modulation." This system employs an acousto-optic modulator (AOM) to receive a laser beam and separate it into a primary beam and multiple diffracted beams based on an input signal. The power of the primary beam is contingent upon this input signal. The system includes a slit for transmitting the primary beam while dumping the diffracted beams. A controller generates a control signal based on feedback regarding the power of the primary beam, and a driver produces the input signal based on this control signal.
