Abstract: A method for manufacturing a humidity alarm device based on laser-induced graphene is performed as follows. Carbon-based films are coated with a hydroxide ion-containing solution and processed by a laser device to generate hydrophilic graphene layers. The hydrophilic graphene layers are peeled off from the carbon-based films, wetted, and respectively wrapped around shaping rods varying in diameter. The wrapped rods are heated and shaped by a drying oven to obtain curled graphene switches. Each curled graphene switch is connected in series with an alarm lamp to form an alarm component. The alarm components are connected in parallel, and then connected to a positive terminal and a negative terminal of a power supply to form the humidity alarm device.

Abstract: A method for synchronous electroplating filling of differential vias and an electroplating device. Laser irradiation is adopted as an external energy field to assist synchronous electroplating filling of differential vias. A mask or digital maskless technology is used to precisely heat the vias with different positions and different sizes. The filling rate of different regions varies with the temperature difference, thereby realizing the synchronous electroplating filling of differential vias in one step. In the processes of immersion pre-wetting by the electroplating liquid and electroplating filling copper, the laser is used for preheating the wafer processed with vias. In these two steps, the laser needs to locally and precisely heat upper surfaces of the micro vias on the wafer through the mask corresponding to the micro vias on the wafer.
