Filmetrics
The Filmetrics 4PP is a characterization tool at the Stanford Nanofabrication Facility that is used for sheet resistance measurement. The Filmetrics 4PP is located in the SNF Paul G Allen L107 Cleanroom and is assigned to the 'All' cleanliness group. The Filmetrics 4PP requires 1.00 hours of training.[1][2]
Sheet resistance is a common electrical property used to characterize thin films of conducting and semiconducting materials. Sheet resistance is a measure of the lateral resistance through a thin square of material, and sheet resistance is independent of the size of the square.[1]
A sheet resistance tool is used in characterization rather than in deposition, lithography, or etch. A sheet resistance tool is typically used after a conductive or semiconductive layer has been formed, implanted, annealed, or otherwise modified, so the electrical continuity and process outcome can be checked before later device steps.
The Filmetrics 4PP is used for sheet resistance measurement. The Filmetrics 4PP is used in characterization workflows.[1][3][2]
