摘要:
A method of manufacturing a semiconductor device using a wiring substrate is provided which can facilitate the handling of the wiring substrate. The method includes the steps of forming a peelable resin layer on a silicon substrate, forming the wiring substrate on the peelable resin layer, mounting semiconductor chips on the wiring substrate, forming semiconductor devices by sealing the plurality of semiconductor chips by a sealing resin, individualizing the semiconductor devices by dicing the semiconductor devices from the sealing resin side but leaving the silicon substrate, peeling each of the individualized semiconductor devices from the silicon substrate between the silicon substrate and the peelable resin layer, and exposing terminals on the wiring substrate by forming openings through the peelable resin layer or by removing the peelable resin layer.
摘要:
A manufacturing method of a semiconductor device incorporating a passive element includes the steps as follows: a redistribution board forming step forms a redistribution board incorporating the passive element on a base board; a semiconductor element mounting step mounts at least one semiconductor element formed on an opposite side surface of the redistribution board with regard to the base board; a base board separating step separates the base board from the redistribution board and exposes the other surface of the redistribution board; a redistribution board mounting step mounts the redistribution board on a package board via electrode pads exposed from the other surface of the redistribution board.
摘要:
In a method for mounting an electronic part on a mounting substrate in that projection electrodes provided on the electronic part are welded by fusion to join connection terminals provided on the mounting substrate, the flux paste includes a base flux and metal grains having diameters smaller than the diameters of projection electrodes and having a thickness so as to form a space between the flux paste and the electronic part when the electronic part is mounted on the mounting substrate and the flux paste is arranged on the mounting substrate. A resin is sealed in the space formed between the electronic part and the mounting substrate after the projection electrodes are joined to the connection terminals.
