摘要:
A semiconductor chip, substrate employing plural bonding steps to ensure complete bonding particularly of peripheral edges. Embodiments include placing an adhesive layer on a chip mounting substrate positioned on a first supporting device, pressing a semiconductor chip against the chip mounting substrate to bond the semiconductor chip temporarily to the chip mounting substrate temporarily bonded chip on a second supporting device, and applying chip to straighten warpage and to bond the chip entirely to the chip mounting substrate.

A semiconductor device and a manufacturing method thereof are provided with downsizing and densification achieved by reducing the thickness of the semiconductor device without increase in area. Terminal electrodes are arranged, in plan view, outside a region where semiconductor chips are arranged. A lower semiconductor chip is placed to overlap in the range of height with the terminal electrodes, an upper semiconductor chip is placed above the lower semiconductor chip, a wire connects the upper and lower semiconductor chips to the terminal electrodes, and an encapsulating resin encapsulates the upper and lower semiconductor chips and wire. The encapsulating resin has its bottom surface coplanar with the bottom surface of the terminal electrodes.

In a semiconductor device fabricating method, a plurality of wafers each having a plurality of chips into is carried and is placed in a die bonder. Chips taken out from the plurality of wafers is bonded together, respectively, and superpose in a stack by bonding layers to form a chip assembly. The chip assembly to a die pad by a bonding layer is bonded. Thus, the die bonder is able to bond the chip assembly consisting of the plurality of chips to the die pad, so that the process time of a die bonding process for bonding the plurality of chips to the die pad is comparatively short, the semiconductor fabricating apparatus produces semiconductor devices at an improved productivity, has a comparatively small scale and needs a comparatively low equipment investment.

A section of predetermined geometry and area is provided on or in a die pad of a lead frame and taken as a mark to be used for checking the position of a semiconductor chip. If the semiconductor chip is placed outside an allowable range in the X direction, the semiconductor chip overlaps the mark, thereby changing the geometry of an observable portion (slanted portion) of the mark. By means of the change, a positional deviation of the semiconductor chip in the X direction can be ascertained. A positional deviation of the semiconductor chip in Y direction is determined, by observing whether or not an electrode is situated between extensions of sides of a certain portion of the section.

摘要:
A high positional accuracy of a semiconductor chip is attained to stabilize the quality of a semiconductor device. In a die bonding process during assembly of an SIP, a microcomputer chip not required to have a high positional accuracy is picked up with a surface non-contact type collet and is die-bonded onto a first chip mounting portion, thereafter, an ASIC chip required to have a high positional accuracy is picked up with a surface contact type collet and die-bonded onto a second chip mounting portion. By thus using two types of collets properly, not only a high positional accuracy of the ASIC chip which has been die-bonded with the surface contact type collet is attained, but also the quality of the SIP is stabilized.
