Abstract:
Methods and apparatuses for laser-assisted electron-beam inspection (EBI) are provided. The apparatus includes an EBI device and a laser illumination device. The EBI device includes an e-beam source configured to emit an incident e-beam, a deflector configured to deflect the incident e-beam to be projected onto a surface of a semiconductor device, and an electron detector configured to detect emergent electrons generated by the incident e-beam projected onto the surface. The laser illumination device includes a laser source configured to generate a laser, and a guiding device configured to guide the laser to be projected onto the semiconductor device. The laser changes the emergent electrons to cause, in a positive mode of the EBI apparatus, a PN junction of an NMOS of the semiconductor device to be in a conduction state.

Claim (Index 6):
The apparatus of  claim 3 , wherein the optical retroreflector comprises:\n a hollow corner cube made by a mirror group; and a second lens, arranged between the second reflector and the hollow corner cube, wherein\n the hollow corner cube is configured to change a position and an incident angle of the emergent laser reflected off the second reflector through the second lens to retroreflect the emergent laser through the second lens back to the second reflector; and \n the second lens is configured to converge the emergent laser reflected off the second reflector toward the hollow corner cube.
