Sheet Resistance Meter – 4 Point Probe (Contact-Type Sheet Resistance / Thin Film Measurement System)
In the semiconductor and thin-film industries, the importance of sheet resistance (Rs) measurement has rapidly increased.Accurate evaluation of a material’s electrical conductivity is essential to ensure stable process quality and yield performance. While non-contact (eddy current or optical) measurement systems have gained attention for their speed and non-destructive nature,the contact-type (4 Point Probe) method remains … Read more
