Metal Electrode Films

Optimum structures and materials for various applications, substrates, and electro-conductive characteristics

Overview

We have been making metallic films for over half a century. Take advantage of our know-how, built through the use of all variety of metals.

Features & Strengths

Point1 Abundant know how regarding metallic resource varieties and characteristics, as well as the structure of laminated film

In order to conduct manufacturing that meets the needs of our customers, Geomatec has acquired a wide variety of metallic material resources.
In FPD application, metallic films with low resistance can be combined with ITO for display quality improvement (fine colorization, speedy response time) and other properties. We provide a wide variety of these metallic films.

Point2 Combine with thin-film pattern formation & etching for customization

List of metallic films

Materials  Resistance comparison with thin films [µΩ·cm] Cost Glass adhesion Wet etching properties
Al 4 Low Average Good
Explanation -
Au 4 High Not good Good
Explanation This material offers low resistance and high durability. Since it display high reflectivity in the infrared range, it is also used in mirrors. It does not adhere well to glass and requires an intermediate layer (adhesive layer).
Cr 20 Low Average Good
Explanation Due to its reliability and ability to be processed, this material is extremely easy to use. However, it has high membrane stress and its effects on the environment are seen as problematic. In addition, since its resistance is not so low, it is not appropriate for low resistance specifications.
Cu 2 Low Not good Good
Explanation Since it offers low resistance, this material provides superior electro-conductivity. However, it does not adhere well to glass and membrane oxidation occurs quickly, leading to changes in heat resistance.
As such, it cannot be used on it own. Lamination or alloying must be considered.
Mo 13 Standard Good Good
Explanation Resistance is low and it is easily processed. However, it is susceptible to water and there are problems with reliability.
Ni 16 Low Not good Average
Explanation Since it is a magnetic material, it is not suited for spattering, but if target plate thickness is monitored, use is possible.
It does not adhere well to glass and cannot be used on its own. Etching is possible with a mixture of phosphoric acid and nitric acid. As such, expectations are high for its use as a protective film with Al alloys and Ag alloys.
Ta 180 Standard Not good Not good
Explanation

This material has superior reliability and is extremely stable. However, it does not adhere well to glass and problems occur with etching. Generally, β-Ta is used, but it is highly resistant. If low resistance is necessary, α-Ta is used.

Comparative Resistance

  • β-Ta: 180 µΩ·cm
  • α-Ta: 25 µΩ·cm
Ti 70 Low Good Average
Explanation -
Ag Alloys Approximately 3.5 High Average Average
Explanation Since silver alloys are highly reflective and offer low resistance, they are used as anti-reflective conductors. However, they are not susceptible to processing and are highly susceptible to UV rays. As such, use is limited to specific clients, rather than broad adoption.
With that said, expectations are high for the material as low resistance products continue to develop.
Al Alloys Approximately 7 Low Good Good
Explanation This material has comparatively superior resistance and is available at low cost.
However, it is extremely susceptible to alkalines, meaning there are problems with reliability. In addition, when the material comes in direct contact with ITO films, the high potential difference between aluminum and ITO leads to galvanic corrosion.
Mo Alloys Approximately 18 Standard Good Good
Explanation These materials maintain the characteristics of pure molybdenum and address some of its problems. Through alloying, the comparative resistance is slightly higher than pure molybdenum.
