Alumina Ceramic Robotic Arm For Wafer Manufacturing

Alumina Ceramic Robotic Arm for Wafer Manufacturing The alumina ceramic robotic arm designed specifically for wafer manufacturing is a highly advanced and crucial component in the semiconductor industry. Material Properties This robotic arm is mainly made of high-purity alumina ceramic. Usually, the amount of alumina in it is more than 95%. This gives it really good mechanical strength. When handling wafers, like when it's precisely positioning and moving them around, it can handle big stresses and strains. Its Mohs hardness is about 9. That means it's really good at resisting scratches and being worn away. This is really important because if there's any damage to its surface, it could bring in contaminants or mess up the accuracy of how the wafers are handled. The thermal properties of the alumina ceramic are also very important. It has a fairly low thermal expansion coefficient, around 6 - 8 × 10⁻⁶ /°C. In wafer manufacturing, controlling the temperature is super critical.…
