Semiconductor equipment operates with high precision, at high throughput, and in harsh environments.
Whether in industrial production environments or University laboratories, equipment is extremely sensitive to drift and down-time, which can result in large losses.
A typical semiconductor wafer fabrication is done in a clean room with a sequential process using on average 30 different manufacturing equipments. A single equipment being down can stop the entire fabrication line. In some semi-industrial clean rooms, equipment can be down for up to a month due to unexpected failure.
In addition, many of those equipments can drift over time, slowly or unexpectedly strongly, leading to wafer-to-wafer process variations and ultimately silicon chip yield loss, or a strong decrease in chip performance in case the chip designer accounts for maximum process variability in its original design.
Both cases are unacceptable, and in this very competitive environment, ON-time, process repeatability and wafer yield are key differentiators. Miraex provides solutions to improve both.
