Semiconductors and MEMS
Given the compatibility of AF 32® eco with silicon components, it functions highly effectively in semiconductor systems. Silicon thinning is becoming an important process in semiconductor component manufacture, and AF 32® eco can be used as a temporary bonding solution with silicon. The same attributes enable it to act as a high-quality wafer-thin glass cover or substrate for MEMS applications.
RF and HF
AF 32® eco has a key role to play in applications involving RF (radio frequency) and HF (high frequency) devices, ranging from the smartphone market to wearable and automotive fields. With a low level of dielectric loss, AF 32® eco can be used as a substrate in SAW filters, converting electrical signals to acoustic waves and back again. These look set to play a key role in the growing 5G communications industry.
Microdisplays
Microdisplays such as LCoS, microOLED, and microLED rely on top-quality glass components such as AF 32® eco to achieve optimum performance. The ability of AF 32® eco to maximize optical transmission quality also makes it ideal for projectors, Near-To-Eye (NTE) devices, head-up and head-mounted displays, and electronic viewfinders, as well as augmented and virtual reality systems.
