Abstract: PROBLEM TO BE SOLVED: To provide a digital cellular phone system capable of setting a group by a user, and to provide a portable telephone used by the system.
SOLUTION: When registration is notified to the digital cellular phone system, it can be determined whether a member in the group is within the communication area of a base station that is the same as the user or is adjacent to the user. When the member in the group is within the communication area of the base station that is the same as the user, notification to the user is made by short message service. Additionally, when the member in the group is in the communication area of the station that is the same as the user, the user can register position information on the member and the distance between the user and the member.

Abstract: PROBLEM TO BE SOLVED: To provide the structure and the manufacturing method of IC on wafer level, which are useful for improving the yield of the manufacture of IC. SOLUTION: An IC structure on wafer level is formed on a semiconductor wafer and it is formed in a plurality of discrete IC blocks on the wafer. Respective IC blocks are used for forming a plurality of IC components of memory cells. Multilayer wiring structure is formed for electrically connecting the IC components in the IC blocks. For disconnecting an IC component which does not normally operate from active use, a first test and a process of restoration are conducted. This completes the, manufacture stage of a manufacture process. For disconnecting an IC block which does not normally operate from active use even in the stage of packaging, a second test and restoration are conducted.

Abstract: PROBLEM TO BE SOLVED: To reduce thickness and surface area by providing a lead frame with a die pad and several leads each having inner and outer lead parts. SOLUTION: A lead frame being used as a film carrier has a die pad 50 and a plurality of leads 56 each constituting inner and outer leads 52, 54. Chips 58, 60, 62, 64, 66 having faces 58a-66a arranged with a plurality of pads 68 on the die pad 50 are contained in one package having volume substantially equal to the total volume of all chips 58-66 which are then wire bonded to the lead frame. According to the structure, a thin package for facing multichip having small surface area can be obtained.

Abstract: PROBLEM TO BE SOLVED: To reduce thickness and surface area by providing a film carrier with a plurality of conductive wires arranged on an insulation film. SOLUTION: Two chips 50, 52 of different size are contained in one package of substantially the same size as that of the larger one of the chips 50, 52 such that the chip 50 has a wider surface area than the chip 52. The chip 52 is placed on same surface as the insulation film 54 of a film carrier 58, a protrusion 66 of the chip 52 is surrounded by the insulation film 54 of the film carrier 58 and a plurality of conductive wires 56 are arranged on an insulation film. These conductive wires 56 are made thinner than a conductive wire being used in another type of carrier and the width thereof is also limited.

Abstract: PROBLEM TO BE SOLVED: To obtain a thin chip scale IC package for multichip having a small surface area by arranging a plurality of chips on a film carrier while facing each other using flip-chip technology and filling the space between chips with an insulating material while exposing the other side of each chip. SOLUTION: A chip scale IC package for multichip uses a film carrier 58 in order to contain multichips 50, 52, 54, 56. Two chips 50, 56 are arranged on two faces of the film carrier 58 while facing each other using flip-chip technology. Each chip 50, 52, 54, 56 has one protrusion 72 connected with the film carrier 58. The space between the chips 50, 52, 54, 56 is filled with an insulating material 76 and the other surface is exposed. Furthermore, signal transmission route is shortened in order to transmit an external signal directly by forming a conductive wire 60 on the film carrier 58.

Abstract: PROBLEM TO BE SOLVED: To obtain a very small chip scale IC package only slightly larger than a chip contained therein by filling the gap between chips with an insulating material to cover the element surface of two chips while exposing the back face thereof thereby forming an insulation compound. SOLUTION: First and second chips 50, 52 have element surfaces 60, 62 facing the opposite side face of a film carrier 58 and bonding pads of two chips 50, 52 are connected electrically with a conductive wire 56 on a film carrier 58 through first and second conductive protrusions 64, 66. An insulating material fills the space between two chips 50, 52 to form an insulation compound 68. The insulation compound 68 seals only the conductive protrusions 64, 66 and the element surfaces 60, 62 of the chips 50, 52 such that the back faces 70, 72 of the first and second chips 50, 52 are exposed.
