What Is a Ceramic Substrate?
Ceramics are hard, electrically insulating, heat and corrosion-resistant, and widely used in glass, concrete, cement, and fine.
Ceramic substrates include alumina substrates, alumina-zirconia substrates, aluminum nitride (AlN), and silicon nitride (Si3N4). These substrates have excellent mechanical strength, electrical insulation corrosion resistance, heat resistance, and thermal conductivity. Ceramic substrates are becoming necessary due to improved reliability and demand for miniaturization.
Applications of Ceramic Substrates
Ceramic substrates are used in various applications, including communication, high-power lighting, thin-film circuit boards, heat-dissipating substrates, evaluation substrates in high-temperature regions, and glazing substrates, taking advantage of their characteristics.

5. High-Frequency Mobile Communication Equipment
IoT communication equipment, antennas, and filters, voltage-controlled oscillators (VCOs), temperature-compensated crystal oscillators (TCXOs)
Features of Ceramic Substrates
Features of ceramic substrates are described below.
- The surface condition is smooth due to few pores (fine particles). Therefore, it has excellent adhesion to thick films and thin film materials.
- Less variation in dimensions, such as external shape, and less warping and bending.
- High heat dissipation and heat resistance. Physically and chemically stable under high heat environments. Some alumina electrode substrates can withstand the heat of 260°C or higher.
- It has excellent mechanical strength.
- It has chemical and oil resistance. The split strength is stable, and there is little variation in shape, dimensions, etc.
- It has excellent insulation properties, high dielectric breakdown voltage, surface resistance, volume resistance, and low dielectric constant.
- With a stable dielectric constant and low dielectric loss tangent, the loss, when used as a high-frequency substrate, can be kept low, which has led to practical applications in various types of high-frequency circuits.
Semiconductor Packages Using Ceramic Substrates
Heat generation accompanying high integration of semiconductor devices is an important issue, and although thermal VIA and other measures have been taken for printed circuit boards, there are limits to high-density mounting and packaging for high-power semiconductors. Although alumina ceramic has been a driving force in this field, it has become problematic in some cases of the highly demanded characteristics of recent years. In recent years, aluminum nitride and silicon carbide have attracted attention as new ceramic materials for semiconductor packaging, replacing alumina ceramic.
Aluminum nitride is not a natural ceramic material and has excellent thermal conductivity with a theoretical value of 320 W/m K. In practice, it is difficult to improve the raw materials, burnout, and heat resistance. With improvements in raw materials, selection of sintering aids, and sintering conditions, it is now being put to practical use at around 180 W/m K.
Silicon carbide ceramics have become a focus of attention as a substrate material since it was found that they can be made into insulators with high thermal conductivity when beryllium oxide is used as a sintering aid. Unlike aluminum nitride, silicon carbide ceramics cannot be multilayered, so they are mainly used in packaging applications.
Advantages of Ceramic Substrates
Among ceramic substrates, LTCC substrates are particularly advantageous in that they enable the high-density mounting of wiring patterns and have excellent high-frequency characteristics.
In particular, LTCC substrates have a thermal expansion coefficient close to that of semiconductor chips such as Si and GaAs chips and can be mounted as bare chips, facilitating modularization by integrating IC chips and chip components such as LCs. Cavity formation and multilayering are also easy, and its superior resistance to moisture and heat is an advantage that should not be overlooked.
