Circuit Edit Systems

Circuit edit technology enables fast prototyping of small design corrections at multiple points of the IC manufacturing process: after first silicon debug, for performance enhancements during yield ramp, to create a small number of functioning chips for beta developers, as well as to resolve reliability issues. Circuit edit engineers mill the chip to the site of the suspected defect, and then remove or deposit conductors or insulators in precise geometries, this way allowing IC manufacturers to validate design changes without re-spinning masks and processing additional wafers.
