Hybrid bonding interconnection using laser and thermal compression
In one example, a method to manufacture a semiconductor device comprises providing an electronic component over a substrate, wherein an interconnect of the electronic component contacts a conductive structure of the substrate, providing the substrate over a laser assisted bonding (LAB) tool, wherein the LAB tool comprises a stage block with a window, and heating the interconnect with a laser beam through the window until the interconnect is bonded with the conductive structure. Other examples and related methods are also disclosed herein.
Dielectric-dielectric and metallization bonding via plasma activation and laser-induced heating
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.
