What it is

General reference — not yet source-verified

A resistivity mapper is a wafer metrology tool used to measure the electrical resistance characteristics of conductive layers and substrates across a wafer surface. Resistivity mappers are used to generate spatial maps that show within wafer variation, helping engineers evaluate process uniformity and detect nonuniform regions after electrically significant process steps.

How it works

General reference — not yet source-verified

Resistivity mappers generally contact the wafer at planned measurement sites and convert the resulting electrical response into sheet resistance or bulk resistivity values. Resistivity mappers generally compile many site measurements into a wafer map so process engineers can review center to edge behavior, local excursions, and patterned or blanket film uniformity.

Where it fits in the process flow

General reference — not yet source-verified

Resistivity mapping tools are used in electrical metrology after processes that set dopant activation or conductive film properties. Resistivity mapping commonly follows implant, diffusion, epitaxial growth, deposition, or metallization steps when engineers need to confirm that a process produced the intended electrical uniformity before later process integration or device evaluation.

Applications

The KLA RS 75 is used to analyze conductive layers including implants, diffusion, epi, CVD, metals, and bulk substrates.[4]
