A solder powder comprises solder particles having a distribution such that the number of particles having a particle diameter of 20 \u03bcm or less is 30% or less, wherein the oxygen content is 500 ppm or less. Embodiments of the present invention improve image quality by effectively nullifying gamma correction in areas where the envelope effect exists, enabling the human eye to perceive the displayed signal without the envelope effect. Then the solid condensate layer and regions of the material layer that were deposited on the solid condensate layer are removed, leaving a patterned material layer on the structure. The maintained packet information serves as the basis for latency analysis. Thereafter, the oxide layer to be repaired is bonded with the repairing oxide layer. Systems and computer program related to the methods are also disclosed.
