Title:
VAPOR CELL COMPRISING ELECTRO-OPTIC FUNCTION FOR CHIP-SCALE ATOMIC CLOCK, AND METHOD FOR MANUFACTURING SEALED CONTAINER FOR CHIP-SCALE INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2017/018846
Kind Code:
A1
Abstract:
According to the present invention, since a silicon body itself supporting first and second glass substrates also has a role of an electric heating device, the temperature of the inside of a through-part can be maintained to be constant. In addition, since it is unnecessary to comprise a separate electric heating device such as a heater or to form an additional heating pattern in order to control the temperature of the inside of the through-part, a process for manufacturing a vapor cell can be simplified. According to the present invention, only a reactive material in a gas state and a buffer gas can be injected into a sealed container without the intervention of other materials, and the size of the sealed container can be reduced since it is unnecessary to prepare a separate space for mounting a pill of the reaction material in a vapor cell region itself.
