First, the preparation of ultra-thick silicon wafers requires higher temperature and pressure conditions, which are more demanding on equipment and processes.
Second, how to ensure the uniformity and consistency of ultra-thick silicon wafers in the growth process is also a problem that needs to be solved.
In the MEMS field, ultra-thin silicon wafers enable the fabrication of even smaller, more sensitive sensors and actuators. These miniaturized sensors and actuators can not only be integrated in a smaller space, but also achieve higher measurement accuracy and faster response time.
For example, in the medical field, miniature sensors made of ultra-thin silicon wafers can be used to monitor patients’ physiological parameters in real time, providing more accurate data to support the diagnosis and treatment of diseases.
In the field of advanced CMOS logic, ultra-thin silicon wafers help to improve the energy efficiency and computing speed of the chip. As chip integration continues to increase and power consumption continues to decrease, ultra-thin silicon wafers have become a key material for realizing this goal.
By using ultra-thin silicon wafers, more efficient and energy-saving chip products can be manufactured to meet the needs of high-performance computing and data processing and other fields.

Second, the technical challenges and application prospects of ultra-thick polished silicon wafers
However, it is these technical challenges that make ultra-thick polished silicon wafers show broad application prospects in high-energy applications.
In high-energy applications, standard commercial thickness silicon wafers are often difficult to withstand extreme energy shocks and temperature changes. Ultra-thick polished wafers are ideal for these applications due to their excellent durability and stability.
For example, in the field of power electronics, ultra-thick polished silicon wafers can be used to manufacture power devices that can withstand high voltages and currents; in the field of automotive electronics, ultra-thick polished silicon wafers can be used to manufacture sensors and actuators that can withstand extreme temperatures and vibration environments.
