An electrostatic thermal bonding method for bonding a pair of glass substrates, is capable of solving the problems such as a contamination of a device and incomplete vacuum packaging due to gas generated during the bonding of glass substrates utilizing a conventional epoxy or frit. The electrostatic thermal bonding method uses a silicon-glass bonding mechanism. First, a silicon thin film is deposited on a metal thin film formed on a side of one glass substrate, and the two glass substrates are brought face to face with each other by bringing the silicon thin film into contact with the surface of the other glass substrate. A predetermined direct current voltage is applied between the metal thin film and the other glass substrate under a predetermined temperature, thereby the bonding between glass substrates is performed. In the glass-glass bonding method utilizing the silicon thin film, the direct current voltage in the range of 0 to 1000V is applied under a bonding temperature between 100 to 500° C. and the elements are combined between a surface of the glass and a surface of the silicon thin film. Therefore, such a bonding results in an improved bonding strength and an improved vacuum packaging.

A device and method for measuring water and oxygen permeation rates of a protective layer in an organic electronic device are provided. The device includes: a glass substrate; a pair of electrode layers facing each other and deposited on the glass substrate; a calcium layer deposited on the glass substrate; a water and oxygen permeable substrate deposited on the calcium layer; a target protective layer of an organic electronic device, which is deposited on the water and oxygen permeable substrate; and a sealing material applied along an edge of the target protective layer, wherein one ends of the pair of electrode layers are buried in the calcium layer and the other ends are electrically connected to an external resistance measuring device.Accordingly, high reliability can be achieved, applicability to various processes for the protective layer in the organic electronic device can be enhanced without affecting reflectance or transmittance of the protective layer, and a defect averaging operation does not need to be performed on a calcium layer within the device unlike the conventional art, by using a principle that electrical characteristics of the device are changed when the water or oxygen permeates the protective layer.
