Abstract: An integrated circuit chip includes a circuit structure, a grounding structure, a bonding layer between the circuit structure and the grounding structure. The circuit structure includes a first substrate, an FEOL structure, and a BEOL structure. The grounding structure includes a second substrate and a grounding conductive layer. The integrated circuit chip includes a first penetrating electrode portion connected to the grounding conductive layer based on extending through the first substrate, the FEOL structure, the BEOL structure, and the bonding layer such that the first penetrating electrode portion is isolated from direct contact with the integrated circuit portion in a horizontal direction extending parallel to an active surface of the first substrate. An integrated circuit package and a display device each include the integrated circuit chip.

Abstract: An apparatus for automatically selecting a telephone service provider that provides a communication service at the most inexpensive fee schedule and a method thereof are disclosed. According to the apparatus and the method, a telephone service provider that provides a communication service at the most inexpensive fee schedule is automatically selected according to the predetermined area, time and provider codes corresponding to a connection signal inputted by the calling part. This effectively provides a telephone service to a user at the lower rate.
