超小型音叉晶体单元和超小型实时时钟模块

晶体芯片的三维光刻处理

具有传统结构的小型化晶体芯片（左图）减小了电极的面积（以红色表示）。
用H形槽结构制造芯片提供了更大的电极面积并提高了电解效率。这种设计使小型化晶体的CI值与普通晶体的CI值一样低（右图）。

Miniaturizing crystal chips with a conventional structure (left image) reduces the area of the electrodes (indicated in red).
Fabricating the chips with an H-groove structure provides a larger electrode area and raises electrolytic efficiency. This design enables miniaturized crystal with CI values as low as those on ordinary-sized crystals (right image).

然而，使用QMEMS技术制造的晶体的CI值保持不变，与常规晶体的水平相当，即使晶体尺寸减小。

The CI value of a crystal fabricated using QMEMS technology, however, remains constant, at a level equivalent to that of conventional crystals, even as crystal size decreases.

HFF晶体单元/ HFF晶体振荡器（高频基波）

为了增加振荡器的频率，必须使芯片更薄，但是传统的处理方法对制造薄芯片施加了限制。

In order to increase the frequency of oscillators, it is necessary to make the chip thinner, but conventional processing methods imposed limitations on producing thin chips.

通过光刻仅处理芯片的振荡部分，能够在不损害晶体芯片强度的情况下实现高频基波，从而形成厚度仅为几微米的极薄的倒置台面结构。

A high-frequency fundamental was enabled without compromising crystal chip strength by photolithographically processing only the oscillating portion of the chip so as to form an extremely thin inverted-mesa structure having a thickness of only several microns.

基频高频振荡的优点

高频基波振荡有助于稳定高速大容量数据传输，因为可以抑制附近的高频分量。

High-frequency fundamental oscillation helps stabilize high-speed, high-volume data transmissions because nearby high-frequency components can be suppressed.
