Hafnium Boride

Hafnium Boride sputtering target is a solid material consisting of the elements hafnium (Hf) and boron (B) used in sputtering deposition technology for the preparation of thin films, which have important applications in many high-tech fields such as semiconductors, optics, wear-resistant coatings, etc. It is a key functional material that possesses the characteristics of high hardness, high melting point and good chemical stability.

Characteristics

Appearance: usually appears as a dark grey solid.

Melting point: up to 3150 ℃ (some data show that it is about 3250 ℃), belongs to the high melting point materials, which makes it still can maintain a stable physical state in the high temperature environment, suitable for the application of high temperature sputtering process scenarios.

Density: The theoretical density is about 10.50g/cm³, high density helps to form a uniform, dense film during the sputtering process.

Hardness: Higher hardness and brittleness ensures both wear resistance and stability of the sputtering target during use and the need for careful handling during processing, transport and installation to avoid damage to the target.

Solubility: insoluble in water, which makes the target less susceptible to the influence of water during storage and use, ensuring the stability of its performance.

Chemical stability: at room temperature, except for hydrofluoric acid (HF), it hardly reacts with other common chemical reagents and has good chemical stability. However, it will react in concentrated hydrochloric acid and concentrated nitric acid mixtures.

Purity: In general, high quality hafnium boride sputtering targets are available in purities of 99.5% and higher. High purity helps reduce the effect of impurities on the performance of sputtered films.

Film uniformity: the ability to form a uniform film thickness distribution on the substrate, which is very important for the preparation of high-quality thin-film devices, such as in the semiconductor, optical and other fields, uniform film thickness can ensure the performance and reliability of the device.

Sputtering efficiency: With high sputtering efficiency, it can form the required thickness of film in a shorter time to improve production efficiency.

Bonding force: Through proper bonding process, a good bonding force can be formed between the target material and the backing plate to ensure that the target material will not fall off from the backing plate during the sputtering process and ensure the stability of the sputtering process.
