In the highly technology intensive field of the semiconductor industry, the requirements for insulation layer materials are extremely demanding. The all hydrogen polysilazane liquid coating material IOTA PHPS, with its unique performance advantages, has become an ideal choice for building semiconductor insulation layers.
IOTA PHPS has many characteristics that meet the requirements of semiconductor insulation layers. Starting from product characteristics, it has good solubility and can be well adapted to commonly used solvents in semiconductor manufacturing processes. It facilitates precise coating operations on the surface of small and precise semiconductor components such as chips, ensuring the uniformity and integrity of the insulation layer. The diversity of curing methods, whether it is long-term curing in a relatively mild room temperature environment or rapid curing under specific temperature and humidity conditions according to specific process requirements, can flexibly meet the time and process limitations of different links on the semiconductor production line, which helps to improve production efficiency and product quality.
From the technical parameters, as a colorless and transparent liquid, it will not interfere with the optical performance of semiconductor components and subsequent testing, packaging, and other processes. The solid content is 20%, and the solvent is n-butyl ether with specific liquid densities (1.16-1.31 g/ml) and cured densities (1.6-2.0 g/ml), ensuring the stability and repeatability of the coating in high-precision environments such as semiconductor manufacturing.
When it comes to coating performance, the coating is mainly composed of SiOx, which has good insulation properties and can effectively block current, prevent electrical faults such as short circuits between different electrodes and circuits in semiconductor components, and provide reliable electrical protection for the stable operation of chips and other components. Its coating thickness is greater than 100nm, which ensures insulation effect without excessively increasing the volume and weight of the components, in line with the development trend of miniaturization and lightweighting of semiconductor products. In terms of hardness, appropriate hardness indicators can be achieved according to different curing methods, ensuring that the insulation layer will not be easily damaged during subsequent processing, packaging, transportation, and use. And the transparency (visible light) is greater than 90%, which will not have any adverse effects on some semiconductor application scenarios that require optical detection or special requirements for light.
In terms of adhesion, the scratch test reaches level 0, which means it can tightly adhere to the surfaces of different materials such as silicon wafers and metal interconnect layers in semiconductors. Even after undergoing complex manufacturing processes, temperature changes, and long-term use, there will be no insulation layer detachment, thus ensuring the reliability and service life of semiconductor products.
In practical applications, in the semiconductor chip manufacturing process, after completing the main circuit manufacturing processes, IOTA PHPS is coated on the corresponding parts through precise coating technology, and then cured according to requirements to create a high-performance insulation layer for the chip. For the semiconductor packaging process, it can also play an insulating and protective role in pins, substrates, and other areas, preventing external static electricity, water vapor, and other factors from damaging the internal circuits of the chip.
In summary, the application of IOTA PHPS coating in semiconductor insulation layers provides strong support for the high-quality development of the semiconductor industry, helping to manufacture more stable and reliable semiconductor products, and meeting the growing demand for high-performance chips and other semiconductor components in modern technology.
