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 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.

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.

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.

This alumina substrate can shine with very smooth surfaces in the true sense of the word due to its fine-grained structure of <2µm particles. Our Keral 99 TF is primarily designed for thin film applications and can be easily cut or patterned by laser or wafer saw. The deposition of platinum is easily implemented using standard thin film technology. Thanks to the advantageous flatness of <200µm (4"x4"), fine will be accurately imaged. The substrates are "Made in Germany" here in Eschenbach in der Oberpfalz.
