This quartz resonator is designed with sealing bonding, wafer thinning, and Cu TSV interconnection.
This silicon-based quartz resonator package is achieved by the Cu TSV interconnection, wafer thinning process, and sealing bonding techniques.
The proposed silicon-based package of quartz resonator adopts several three-dimensional (3D) core technologies, such as Cu TSVs, sealing bonding, and wafer thinning.
The 3D scheme combined with sealing bonding techniques by using sealing wafer level packaging of micro electro mechanical system (MEMS) component is successfully achieved, such as SAW RF Filter, silicon MEMS oscillators, and image sensor devices [18 22].
However, challenges and issues of current manufacturing of ceramic-based quartz resonator package, including high-cost packaging material of metal lid, one chip sealing bonding, and scaling limit of ceramic substrate, make the shrinkage of quartz resonator packages difficult.
Polymers are highly important in industrial applications such as bearings, seals, bonds and coatings.
Moisture adds the sealing bond".
Although they were not used literally as visiting cards, they helped seal social bonds, so much so that Oliver Wendell Holmes called them the "sentimental greenbacks of civilization".
But it's not: the sight of a private moment on public display helps seal a bond between the nation and the viewer called upon to endure personal sacrifices on behalf of the Union.
cycle or brief blip of pregnancy offered the hope that I might soon be a mother, might seal the bonds of my marriage with a child, might soon be able to stopper the abyss of grief that threatened to suck me under every day.
