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.
BONDING METHOD, BONDED ARTICLE, AND BONDING DEVICE
A bonding device measures a position deviation amount of the chip with respect to the substrate in a state where the chip and the substrate are in contact, and corrects and moves the chip relatively to the substrate in such a way as to reduce the position deviation amount, based on the measured position deviation amount. Then, the bonding device fixes the chip to the substrate by irradiating a resin portion of the chip with an ultraviolet ray and curing the resin portion when the position deviation amount of the chip with respect to the substrate is equal to or less than a position deviation amount threshold value.
Chip bonding apparatus
Embodiments in accordance with the present inventive concept disclose a chip bonding apparatus that includes a stage configured to support a substrate and a heater that is disposed above the stage. The heater includes a heat generating portion and a body portion. The chip bonding apparatus further includes a bonding tool assembly fixing unit having a first portion connected to the body portion of the heater, and a second portion configured to receive the heat generating portion. The chip bonding apparatus further includes a first bonding tool connected to the heat generating portion; and a first bonding tool fixing unit having a third portion that is connected to the first portion, and a fourth portion configured to receive the first bonding tool. The bonding tool fixing unit may be attached by an electrostatic force or by coupling between a notch gripper and a corresponding notch.
SEMICONDUCTOR DEVICE MANUFACTURING DEVICE AND MANUFACTURING METHOD
This semiconductor device manufacturing device comprises: a stage; a bonding head; a copying mechanism provided on the bonding head; and a controller that executes the copying process to adjust a facing surface to be parallel to a reference plane by having the facing surface, which is a holding surface or a chip end face, follow the reference plane 110, which is a planar surface of the stage or a substrate. In the copying process, the controller moves the bonding head relative to the surface direction of the reference plane with the facing surface left abutting the reference plane in a state with the copying mechanism switched to a free state, until the axial direction position of the bonding head reaches a stipulated reference position, and when the axial direction position reaches the reference position, switches the copying mechanism to a locked state.
