Abstract

The invention relates to a semiconductor package and a manufacturing method for a semiconductor package as well as an optical module. The semiconductor package includes: a supporting substrate; a functioning element and a first joining element formed on a first principal surface of the supporting substrate; a sealing substrate disposed in an opposing relationship to the supporting substrate with the functioning element and the first joining element interposed therebetween; a second joining element provided on a second principal surface of the supporting substrate; a through-electrode provided in and extending through the supporting substrate and adapted to electrically connect the first and second joining elements; and a first electromagnetic shield film coated in an overall area of a side face of the supporting substrate which extends perpendicularly to the first and second principal surfaces.

Description

technical field [0001] The technology disclosed in the present invention relates to a semiconductor package such as a WCSP (Wafer Level Chip Scale Package) and a WLCM (Wafer Level Camera Module) using the semiconductor package. Background technique [0002] With the improvement of integration technology in recent years, reduction in size and weight of electronic devices, reduction in operating voltage and power consumption, and increase in operating frequency have been rapidly advanced. Therefore, demand for area array type packages such as BGA (Ball Grid Array), LGA (Land Grid Array), and CSP (Chip Scale Package) is increasing. Recently, advanced technologies such as WCSP using through-hole electrodes have also begun to spread. [0003] A WCSP is a semiconductor package formed by performing a forming process step of sealing resin or external terminals at the stage of a wafer before dicing. With the WCSP of the kind just described, when the chip is mounted on a printed boa...
