A module (1) includes a substrate (12) and a plurality of semiconductor packages (11a, 11b), each including a semiconductor chip (10), mounted on the substrate (12). Each of the plurality of semiconductor packages (11a, 11b) includes a first radio communication element (16) for transmitting and receiving a signal between the semiconductor chips (10) in the plurality of semiconductor packages (11a, 11b) by radio communication, and the first radio communication element (16) is constituted independently of the semiconductor chip (10).
Abstract:
The aim of the disclosed invention is to provide a capacitor-built-in-type printed wiring substrate which can reliably eliminate noise and attains extremely low resistance and low inductance involved in connection between an IC chip and the capacitor and to provide a printed wiring substrate and a capacitor used in the same. To achieve this object, a capacitor-built-in-type printed wiring substrate (100) on which an IC chip is mounted includes a capacitor-built-in-type printed wiring substrate (110) and an IC chip (101) mounted on the capacitor-built-in-type printed wiring substrate (110). A printed wiring substrate (120) includes a number of connection-to-IC substrate bumps (152) and a closed-bottomed capacitor accommodation cavity (121) formed therein. A capacitor (130) is disposed in the cavity (121) and includes a pair of electrode groups (133E and 133F) and a number of connection-to-IC capacitor bumps (131) connected to either one of the paired electrode groups (133E and 133F). The connection-to-IC capacitor bumps (131) are flip-chip-bonded to corresponding connection-to-capacitor bumps (103) on the IC chip. The connection-to-IC substrate bumps (152) are flip-chip-bonded to corresponding connection-to-substrate bumps (104) on the IC chip.
Abstract:
In the past, a power supply distance between a power source and an LSI package could not be shortened and power supply variations could easily produce an adverse effect. In the present invention, a power supply module 11 is mounted on the surface of an LSI package 13 . The power supply distance between the LSI 19 and power supply module 11 can be shortened. As a result, the power source noise can be reduced, the efficiency and response rate of the power source unit are high, and the generated electromagnetic field can be reduced. Moreover, since each LSI package has a power supply module required therefor, the number of required power source types (voltage types) on the substrate with the package mounted thereon can be decreased. As a result, the mounting efficiency can be increased and the substrate can be manufactured at a low cost.
Abstract:
Apparatus and methods of electrically connecting integrated circuits (40-50) and transducers (28-38) are described. In particular, a transducer (60) includes a base (62) mountable on a substrate (64) (e.g., a printed circuit board), and an input/output (I/O) lead (66) configured to contact an I/O lead (68) of an integrated circuit (70) mounted on the substrate (64). The transducer (60) may be mounted on the substrate (64) to contact the transducer I/O lead (66) to the integrated circuit I/O lead (68). The transducer I/O lead (66) is configured to electrically connect to the integrated circuit I/O lead (68) independently of any electrically conductive path of the substrate (64). The direct electrical connection between the transducer (60) and the integrated circuit (70) provides a high-speed communication channel that avoids the parasitic and high-inductance limitations generally associated with conventional metallic printed circuit board traces. At the same time, the transducer (60) is compatible with existing printed circuit board technologies and integrate circuit technologies and, therefore, may be readily integrated into existing computer systems.
