Abstract: A method and apparatus for detecting VC defects and determining the exact shorting locations based on charging dynamics induced by scan direction variation are provided. Embodiments include providing a substrate having at least a partially formed device thereon, the partially formed device having at least a word-line, a share contact, and a bit-line; performing a first EBI on the at least partially formed device in a single direction; classifying defects by ADC based on the first EBI inspection; selecting DOI among the classified defects for further review; performing a second EBI on the DOI in a first, second, third, and fourth direction; comparing a result of the first direction against a result of the second direction and/or a result of the third direction against a result of the fourth direction; and determining a shorting location for each DOI based on the one or more comparisons.

Abstract: At least one method, apparatus and system disclosed herein fin field effect transistor (finFET) comprising a bulbous fin head. A fin of a gate of a transistor is formed. A first recess step is performed for striping a hard mask material by a first dimension to expose a first portion of the fin. An epitaxy layer is formed upon the first portion. An oxidation process is performed upon the fin. An oxide removal process is performed upon the fin to provide a bulbous shape upon the first portion.
