Veridiam, via its Veridiam Point Technologies unit, is the leading manufacturer of probe needles used for wafer testing, critical metal wire components, subcomponents and assemblies. Using our precision, electrochemical pointing process, we are able to etch small diameter wires to achieve extremely tight tolerance tapers and sub-micron points.

• Semiconductor Probe Needles
• PCB Test Probes
• Electrodes
• Ion Emitters
• Micro-Machined Components
• ...and many, many more!

Specializing in Tungsten, Tungsten Rhenium and Beryllium Copper. We are also able to work with other conductive metals and alloys. Please contact us to discuss your application.

• Taper Lengths from 0.030" to 2"
• Part Lengths from 0.300" and up

A semiconductor is a material that has an electrical conductivity due to flowing electrons (as opposed to ionic conductivity) which is intermediate in magnitude between that of a conductor and an insulator. This means roughly in the range 10₃ to 10-₈ siemens per centimeter. Devices made from semiconductor materials are the foundation of modern electronics, including radio, computers, telephones, and many other devices. Semiconductor devices include the various types of transistor, solar cells, many kinds of diodes including the light-emitting diode, the silicon controlled rectifier, and digital and analog integrated circuits. Similarly, semiconductor solar photovoltaic panels directly convert light energy into electrical energy. In a metallic conductor, current is carried by the flow of electrons. In semiconductors, current is often schematized as being carried either by the flow of electrons or by the flow of positively charged "holes" in the electron structure of the material. Actually, however, in both cases only electron movements are involved.   [Source]
