A content joint editing method according to an embodiment of the inventive concept may preserve the real-time property of update of edits as much as possible even if the number of editors increases when multiple editors simultaneously edit content. A content editing method can share and edit various contents without calling a separate external application in an online collaboration service. A content sharing method can manage each user's access rights to a content in individual content units in collaboration service that displays a plurality of contents at the same time in the collaboration space for sharing contents among multiple users.

An MEMS device using an SOI wafer includes a first silicon layer, an insulation layer formed on the first insulation layer, a second silicon layer formed an the insulation layer, a protective layer formed on the second silicon layer, and a ground hole extending from an upper portion of the protective layer to the first silicon layer and having a conductive material therein. A handle wafer in the MEMS device is connected to the ground hole without performing any additional wiring or bonding process.
