Applications

Semiconductor field: In the manufacture of semiconductor devices, it can be used to prepare semiconductor films. For example, specific functional layers are formed on the surface of semiconductor chips by the sputter coating process, which play a key role in the performance and function of the chip. For example, they are involved in the formation of semiconductor doping layers, barrier layers, and other structures, which help to realise the transmission and control of electrons and enhance the performance and stability of semiconductor devices.

Solar cell field: It can be used in the manufacture of thin film solar cells. In thin-film solar cells, cadmium selenide can be used as an absorbing layer material, and cadmium selenide is deposited on the substrate to form a thin film through sputtering targets, which can effectively absorb sunlight and convert it into electricity, improving the photoelectric conversion efficiency of solar cells.

Optical field: used for the preparation of optical films, such as transmittance enhancement film, reflective film. Cadmium selenide sputtering targets can form high-quality thin films on the surface of optical elements, and these films can change the reflection, refraction and absorption characteristics of the optical elements to light, so as to meet the needs of different optical applications. For example, in lasers, optical sensors, optical lenses and other optical devices, cadmium selenide optical films can improve the performance and stability of the device.

Flat panel display field:
In flat panel display technology, such as liquid crystal display (LCD), organic light-emitting diode display (OLED), cadmium selenide sputtering targets can be used to prepare electrodes or functional layers. Through precise control of the sputtering process, a uniform, high-quality film can be formed on the display panel, improving the display panel’s resolution, colour saturation and contrast and other properties.
