摘要: Various methods and apparatus are provided for testing an ion implantation tool. In one aspect, a method of testing an ion implanter is provided that includes forming a mask with a preselected pattern on a substrate. An ion implant is performed on the mask with the ion implanter. Following the ion implant, a scan of the mask is performed to identify any defects thereon. Defects appearing on the mask following the implant are indicative of latent mechanisms at work within the implanter. Ion implanter induced defects may be economically analyzed.

摘要: Various methods of inspecting circuit structures are provided. In one aspect, a method of detecting structural defects in a circuit structure is provided. A natural frequency of the circuit structure is determined and the circuit structure is immersed in a liquid. A first plurality of sonic pulses is sent through the liquid. The first plurality of sonic pulses have a first frequency range selected to produce a plurality of collapsing bubbles proximate the circuit structure. The collapsing bubbles produce a second plurality of sonic pulses that have a second frequency range near or including the natural frequency of the circuit structure whereby the second plurality of sonic pulses causes the circuit structure to resonate. Thereafter, the circuit structure is inspected for structural damage. Early identification of crystalline defects is facilitated.
