Sapphire Substrates Description
Sapphire substrates are ideal for use instead of glass substrates when optical transmission is required in the ultraviolet (above 200 nm) or infrared (below 5 μm) range. Low-temperature optical measurements will also benefit from the higher thermal conductivity of sapphire substrates, and they may also be used in high temperature environments up to 2300 K.
Detail & Parts
Sapphire Glass Properties
- Chemical Properties: Sapphire, a crystalline form of aluminum oxide (Al2O3), exhibits remarkable chemical resistance to acids and alkalis, including hydrofluoric acid. Its hexagonal lattice structure consists of Al3+ cations and O2- anions.
- Mechanical Properties: With a Mohs hardness of 9, second only to diamond, sapphire is highly scratch-resistant. Glass, in comparison, has a hardness of approximately 5.5.
- Optical Properties: Sapphire, though birefringent, is precisely cut along the C-plane to eliminate polarization-dependent birefringence for normally incident light. It offers excellent transparency to wavelengths between 200 nm and 5 µm, making it ideal for UV and near/mid-IR applications. In the visible spectrum, sapphire has a refractive index of approximately 1.76.
- Thermal Properties: Sapphire exhibits a high thermal conductivity of ~40 W/m.K at room temperature, nearly 50 times greater than that of glass and twice as high as stainless steel. Its thermal conductivity increases to ~10000 W/m.K at reduced temperatures, making it well-suited for low-temperature optical measurements. It can also withstand high-temperature environments up to 2300 K. Our sapphire substrates are polished to optical quality, with significantly lower RMS roughness compared to glass substrates.

What are the materials used in thin film deposition?
Thin film deposition commonly utilizes metals, oxides, and compounds as materials, each with its unique advantages and disadvantages. Metals are preferred for their durability and ease of deposition but are relatively expensive. Oxides are highly durable, can withstand high temperatures, and can be deposited at low temperatures, but can be brittle and challenging to work with. Compounds offer strength and durability, can be deposited at low temperatures and tailored to exhibit specific properties.
The selection of material for a thin film coating is dependent on the application requirements. Metals are ideal for thermal and electrical conduction, while oxides are effective in offering protection. Compounds can be tailored to suit specific needs. Ultimately, the best material for a particular project will depend on the specific needs of the application.

What are the methods to achieve optimal thin film deposition?
To achieve thin films with desirable properties, high-quality sputtering targets and evaporation materials are essential. The quality of these materials can be influenced by various factors, such as purity, grain size, and surface condition.
The purity of sputtering targets or evaporation materials plays a crucial role, as impurities can cause defects in the resulting thin film. Grain size also affects the quality of the thin film, with larger grains leading to poor film properties. Additionally, the surface condition is crucial, since rough surfaces can result in defects in the film.
To attain the highest quality sputtering targets and evaporation materials, it is crucial to select materials that possess high purity, small grain size, and smooth surfaces.
Uses of Thin Film Deposition
Zinc Oxide-Based Thin Films
ZnO thin films find applications in several industries such as thermal, optical, magnetic, and electrical, but their primary use is in coatings and semiconductor devices.
Thin-Film Resistors
Thin-film resistors are crucial for modern technology and are used in radio receivers, circuit boards, computers, radiofrequency devices, monitors, wireless routers, Bluetooth modules, and cell phone receivers.
Magnetic Thin Films
Magnetic thin films are used in electronics, data storage, radio-frequency identification, microwave devices, displays, circuit boards, and optoelectronics as key components.
Optical Thin Films
Optical coatings and optoelectronics are standard applications of optical thin films. Molecular beam epitaxy can produce optoelectronic thin-film devices (semiconductors), where epitaxial films are deposited one atom at a time onto the substrate.
Polymer Thin Films
Polymer thin films are used in memory chips, solar cells, and electronic devices. Chemical deposition techniques (CVD) offer precise control of polymer film coatings, including conformance and coating thickness.
Thin-Film Batteries
Thin-film batteries power electronic devices such as implantable medical devices, and the lithium-ion battery has advanced significantly thanks to the use of thin films.
Thin-Film Coatings
Thin-film coatings enhance the chemical and mechanical characteristics of target materials in various industries and technological fields. Anti-reflective coatings, anti-ultraviolet or anti-infrared coatings, anti-scratch coatings, and lens polarization are some common examples.
Thin-Film Solar Cells
Thin-film solar cells are essential to the solar energy industry, enabling the production of relatively cheap and clean electricity. Photovoltaic systems and thermal energy are the two main applicable technologies.

Factors and Parameters that Influence Deposition of Thin Films
Deposition Rate:
The rate at which the film is produced, typically measured in thickness divided by time, is crucial for selecting a technology suitable for the application. Moderate deposition rates are sufficient for thin films, while quick deposition rates are necessary for thick films. It is important to strike a balance between speed and precise film thickness control.
Uniformity:
The consistency of the film across the substrate is known as uniformity, which usually refers to film thickness but can also relate to other properties such as the index of refraction. It is important to have a good understanding of the application to avoid under- or over-specifying uniformity.
Fill Capability:
Fill capability or step coverage refers to how well the deposition process covers the substrate's topography. The deposition method used (e.g., CVD, PVD, IBD, or ALD) has a significant impact on step coverage and fill.
Film Characteristics:
The characteristics of the film depend on the application's requirements, which can be categorized as photonic, optical, electronic, mechanical, or chemical. Most films must meet requirements in more than one category.
Process Temperature:
Film characteristics are significantly affected by process temperature, which may be limited by the application.
Damage:
Each deposition technology has the potential to damage the material being deposited upon, with smaller features being more susceptible to process damage. Pollution, UV radiation, and ion bombardment are among the potential sources of damage. It is crucial to understand the limitations of the materials and tools.
