Wherein, the first image capturing device and the second image capturing device capture an entire image of a to-be-measured object, the third image capturing device and the fourth image capturing device capture a plurality of local images of a plurality of local areas of the to-be-measured object, and the entire image and the local images and are simultaneously captured.

Measurement equipment

A manufacturing process for a thermally enhanced package is disclosed. First, a substrate strip including at least a substrate is provided. Next, at least a chip is disposed on an upper surface of the substrate, and the chip is electrically connected to the substrate. Then, a prepreg and a heat dissipating metal layer are provided, and the heat dissipating metal layer is disposed on a first surface of the prepreg and a second surface of the prepreg faces toward the chip. Finally, the prepreg covers the chip by laminating the prepreg and the substrate.

Thermally enhanced package structure

A flip chip package process is provided. First, a substrate strip including at least one substrate is provided. Next, at least one chip is disposed on the substrate, and the chip is electrically connected to the substrate. Then, a stencil having at least one opening and an air slot hole is disposed on an upper surface of the substrate strip, an air gap is formed between the stencil and the substrate strip, the air gap connects the opening and the air slot hole, and the chip is located in the opening. Finally, a liquid compound is formed into the opening of the stencil to encapsulate the chip, and a vacuum process is performed through the air slot hole and the air gap, so as to prevent the air inside the opening from being encapsulated by the liquid compound to become voids.

Flip chip package process

A structure and method of forming a metal buffering layer during the formation of a redistribution layer is provided. It only changes a mask to form the metal buffering layer and circuit traces simultaneously. The metal buffering layer can increase the flatness of the dielectric layer covering on the metal buffering layer. It can also make the structure under the metal buffering layers suffer uniform pressure to prevent the passivation layer from cracking and the circuit traces from collapsing in order to increase the yield of the packaged chips.

Structure and method of forming metal buffering layer

A semiconductor package includes a flip chip mounted on a plurality of leads and encapsulated by a molding compound. The upper surfaces of the leads includes a plurality of bump-bonding regions at the fan-in ends of the leads, and the lower surfaces of the leads include a plurality of outer connecting regions at the fan-out ends of the leads. A plurality of indentations are formed at the upper surfaces of the leads and adjacent to the corresponding bump-bonding regions so as to avoid solder contamination on the leads. After molding, the indentations are filled with the molding compound. Preferably, the indentations have a reversed '&#x3a9;'-shaped profile to prevent bumps of the flip chip from excessively wetting over the other portions of the leads to firmly fix the fan-in ends of the leads.

Semiconductor package with a flip chip on a solder-resist leadframe

A wafer level package mainly comprises a semiconductor wafer and a plurality of bonding pads disposed on the active surface of the wafer. It is characterized in that there is a protection layer formed on the back surface of the wafer, wherein the wettability of the solder material with the protection layer is lower than the wettability of the solder material with the bonding pads. In such a manner, the protection layer will prevent the back surface of the wafer from being contaminated with the solder material. Moreover, when a UBM layer is further provided on the bonding pad, the wettability of the solder material with the protection layer is lower than the wettability of the solder material with the UBM layer.
