Introduction
MEMS clock timing device provided by SiTime.
This time, we will deliver the contents focused on the production.
Unique strengths of SiTime - What is EpiSeal™?
SiTime products have a lineup of MEMS products, and have been appealing to the market since their release to differentiate themselves from crystal products.
One of them is that it does not age (deteriorate over time).
SiTime boasts a market share of about 90% among manufacturers of MEMS oscillators. How do you differentiate yourself in aging compared to other manufacturers?
Do you know what happens when dry etching is performed in the manufacturing process for a normal MEMS product (in this case, a MEMS oscillator)?
As a result, wrinkles remain on the device surface. This causes aging.
SiTime solves this problem with a certain patented technology.
It's called EpiSeal™, a technology that dissolves wrinkles, recrystallizes, and smoothes the surface.
Even if there are impurities, they can be removed by EpiSeal™, soaging can be suppressed to extremely low levels.
Specifically, on a MEMS resonator built into a silicon wafer,
SiTime's patentedtechnology, which forms a silicon epitaxial film in a high temperature environment of 1100°C in a vacuum.
At the end
What did you think.
When trying to manufacture a MEMS product with a frequency stability of 5ppm or less, a vibrator that suppresses aging is essential.
The more high-performance clock sources you need, the more strength you have.
