摘要:
A pressure sensor has a sensor chip with a diaphragm formed therein and bumps formed thereon, and a stem with leads extending from a surface thereof to the sensor chip. The bumps and the leads are electrically connected by face down bonding so that a surface of the sensor chip faces the surface of the stem. In this manner, bonding wires are unnecessary. Therefore, an area for disposing the bonding wires in the stem can be cut down, so that the pressure sensor can be miniaturized.

A manufacturing device of a semiconductor package includes: a holding element for holding a substrate; a bonding element for holding the package and bonding a first metal bump of the package to a second metal bump of the substrate; a monitoring element for irradiating an infrared light toward the substrate and monitoring an electrode pad under the second metal bump based on a reflected light reflected on the pad; and a determination element for determining a state of a bonding surface between the first and second metal bumps based on monitoring information of the pad. The monitoring element faces the bonding element through the holding element, the substrate and the package.
