4-Point Probe [NPS Version]
4-point probe is a high accuracy probe for measurement of resistivity.
DC Four Point Probe systems is one of the most reliable methods for resistivity or sheet resistance measuring of conductive materials.
It is a well known fact among engineers that the quality of the probing apparatus greatly affects the probing accuracy.
Especially, durability is important during the measurement of semiconductor materials as well as the accuracy.
Our 4-point probe manufactured by skilled worker is universally acknowledged as a high accuracy probe, and now many enterprise use the device as standard.
The newly developed needle has a one-piece structure made of highly durable metal, and uses a low-resistance metal for the connection part to maintain good electrical conductivity, We ensure the accurate measurement of variety samples by conducting NPS's unique "Micro-edge contact" treatment. (IP, MT, SB, EP etc. for types of wafers )
We possesses a lot of experiences and solid accomplishments in this field.
high accuracy, hight durability, world standard instrument, quick repair, unique design, etc.

■ New 4-point probe
Nearly half a century has passed since the high-performance four-point probe was first introduced by NPS in Japan. Today it is used as a standard instrument for resistivity measurement electrodes.
NPS is developing, manufacturing and marketing new 4-point probes with high accuracy, durability and cost performance, based on the technical know-how of 4-point probes accumulated over many years and on the expertise of our engineers who are well versed in their characteristic.
The new 4-point probes have the following features.
Major improvements and features:
improvement of fatal defects of conventional products (made by JANDEL and MPP)
Made in Japan.
