Thin- and thickfilm substrates

KERAFOL® offers special sensor substrates for thin- and thickfilm applications.


Thinfilm technology

Thinfilm layers ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. Electronic semiconductor devices, special sensors are the main applications for thin-film technology. The average thickness of circuits is 1 µm.
The circuits are mainly done for thin film substrates are coated by a PVD process.
Therefore, high demands with respect to the surface and grainsstructure of the ceramic substrate are made. The ceramic powder for the particular sensor substrate material must therefore have a particle size of about 1 micron.

Thickfilm Technology

Thick film is used to produce electronic devices such as sensors, hybrid integrated circuits and surface mount devices based on LTCC or HTCC technology.
The conductivity paths for thick film application are applied by screen printing on substrates or tapes.

Keraprotec
partially stabilised zirconia

Keraprotec is a specific partially stabilised zirconia oxide substrate for thinfilm applications. This substrate material combines good electrical insulating properties (at room temperature) with a high bending strength and high fracture toughness. Due to the very fi ne grains and evenness of the Keraprotec very fine Pt-structures are possible.

We lasercut the material according to your wishes! Please send in your CAD data.

Advantages

  • very fine-grained homogeneous grain structure
  • good electrical insulation properties at room temperature
  • very good mechanical strength
  • can be cut by laser or waver saw
  • good planarity
 

Applications

  • sensor substrates
  • sensor protection plate

 

3YSZ-Sensor
3mol % Yttria stabilized zirconia

3YSZ is a special partially stabilized zirconia which is for thin film applications. Among others, it can also be used as an ion conductive ceramic membrane for Solid Oxide Fuell Cells (SOFC). This material is characterized by its excellent flexibility, extremely high bending strength and high fracture toughness. Another advantage is that this material can be manufactured in extremly thin thicknesses.

The standard substrate thickness is 0.15 mm, the minimal thickness just 40 µm. Other dimension are possible. Please send in your inquiry.

    of 1 μm
  • good electric insulation properties at room temperature
  • extremely good mechanical strength
  • can be cut by laser or wafer saw
  • good evenness
  • standard thickness of 0.15 mm with high flexibility
  • producible with a minimal thickness of 40 µm
 

Applications

  • sensor substrate for thin film application
  • sensor protection plate

 

ATS
Alumina thin film substrates

This zirconia thoughened alumina substrate material shows very good results after laser scribing and breaking, or even when cut with a waver saw. ATS is especially for thinfilm applications. ATS can be easily cutted or structured by laser or waver saw. Due to its inner mechanical strength and fine grains the material has much less material chipping at the processing edges during manufacturing process compared to other materials. Due to the very fine grains of the ATS very fine Pt-structures are possible.

Advantages

  • very fine-grained homogeneous grain structure
    < 1 micron
  • good electrical insulation properties
  • high mechanical strength
  • processing by laser or waversaw possible, very low on chipping
  • very good evenness
  • outstanding performance for thinfilm applications
 

Main Applications

  • thinfilm application, e.g. temperature sensors

 

Keral 99
Alumina 99.7%

Keral 99 is a high alumina substrate material with 99.7% purity. Due to the high degree of purity and the fine grain structure, it has a very high thermal conductivity up to 30 W / mK. The dielectric strength is the highest of Kerafol´s ceramic substrate materials.
