MANUFACTURING APPARATUS AND MANUFACTURING METHOD OF SEMICONDUCTOR DEVICE
A manufacturing apparatus of a semiconductor device includes a stage, a mounting tool, a pressing mechanism, and a controller. The pressing mechanism moves the mounting tool in a vertical direction and applies a load to a chip. The controller is configured to perform a first process and a detection process. In the first process, after bringing the chip into contact and until a bump melts, the chip is heated by the mounting tool and a command position of the pressing mechanism is constantly updated so that a positional deviation is constant. In the detection process, melting of the bump is detected based on a decrease in the pressing load.
SUBSTRATE BONDING
A method of preparing a substrate for substrate bonding is provided. The method comprises: forming a recess in a substrate surface of the substrate, and forming a bondable dielectric layer on the substrate surface of the substrate. The bondable dielectric layer has a bonding surface on an opposite side of the bondable dielectric layer to the substrate surface, wherein the recess and the bondable dielectric layer define a dielectric cavity having a dielectric cavity volume. A plug is formed configured to make electrical contact to the substrate in the dielectric cavity volume. The plug has a plug volume which is less than the dielectric cavity volume, wherein the plug extends from the dielectric cavity beyond the bonding surface in a direction generally normal to the bonding surface. The plug is coined by compressing the substrate between opposing planar surfaces such that a contact surface of the plug is made co-planar with the bonding surface.

Employing deformable contacts and pre-applied underfill for bonding LED devices via lasers
The invention is directed towards enhanced systems and methods for employing a pulsed photon (or EM energy) source, such as but not limited to a laser, to electrically couple, bond, and/or affix the electrical contacts of a semiconductor device to the electrical contacts of another semiconductor devices. Full or partial rows of LEDs are electrically coupled, bonded, and/or affixed to a backplane of a display device. The LEDs may be μLEDs. The pulsed photon source is employed to irradiate the LEDs with scanning photon pulses. The EM radiation is absorbed by either the surfaces, bulk, substrate, the electrical contacts of the LED, and/or electrical contacts of the backplane to generate thermal energy that induces the bonding between the electrical contacts of the LEDs' electrical contacts and backplane's electrical contacts. The temporal and spatial profiles of the photon pulses, as well as a pulsing frequency and a scanning frequency of the photon source, are selected to control for adverse thermal effects.

Embodiments of methods and apparatus for reducing warpage of a substrate are provided herein. In some embodiments, a method for reducing warpage of a substrate includes: applying an epoxy mold over a plurality of dies on the substrate in a dispenser tool; placing the substrate on a pedestal in a curing chamber, wherein the substrate has an expected post-cure deflection in a first direction; inducing a curvature on the substrate in a direction opposite the first direction; and curing the substrate by heating the substrate in the curing chamber.
Method of manufacturing a semiconductor package and apparatus for performing the same
In a method of manufacturing a semiconductor package, information with respect to a downward warpage of a reference package substrate, which may be bent with respect to a long axis and/or a short axis of the reference package substrate in applying heat to the reference package substrate to which a plurality of semiconductor chips may be attached using a die attach film (DAF), may be obtained. A package substrate, which may include a first surface to which the semiconductor chips may be attached using the DAF and a second surface opposite to the first surface, may be rotated with respect to the long axis or the short axis at an angle selected based on the information. The heat may be applied to the package substrate to cure the DAF and correct a warpage of the package substrate. Thus, warpage of the package substrate may be corrected for.
