Abstract: A method for adjusting furnace temperature of a reflow oven by AI, through obtaining product data of the reflow oven, obtaining initial characteristic data of a preceding work station and calculating mean values of temperatures of an upper furnace and a lower furnace, and taking the mean values as initial reflow characteristic data. Data as to first reflow characteristics of each reflow temperature zone and second reflow characteristics data of each zone are obtained, and data of the first and second reflow characteristics data are obtained. The electronic device further combines the characteristic data of the preceding work station with the combined reflow characteristics and combines results into a trained neural network model to output a temperature prediction, the oven temperature being adjusted according to the temperature prediction.

Abstract: A patterning method includes sequentially forming a target layer, a first layer, a second layer, a third layer, and a first mask pattern. A first spacer is formed on a sidewall of the first mask layer. The first mask pattern is removed to form a plurality of peripheral openings surrounding a central opening in the first spacer. A rounding process is performed to round the peripheral openings and form a second mask pattern. A portion of the second layer is removed by using the second mask pattern as a mask, so as to form a third mask pattern. A second spacer is formed in the third mask pattern. The third mask pattern is removed. Portions of the first layer and the target layer are removed by using the second spacer as a mask.
