摘要

A first aspect of the present invention provides a method for producing a semiconductor laminate comprising a substrate having formed thereon a silicon layer with small surface unevenness and high continuity. The method of the first aspect of the present invention for producing a semiconductor laminate having a substrate 10 and a sintered silicon particle layer 5 on the substrate comprises (a) coating a silicon particle dispersion containing a dispersion medium and silicon particles dispersed in the dispersion medium, on a substrate 10 to form a silicon particle dispersion layer 1, (b) drying the silicon particle dispersion layer 1 to form a green silicon particle layer 2, (c) stacking a light-transmitting layer 3 on the green silicon particle layer, and (d) irradiating the green silicon particle layer 2 with light through the light-transmitting layer 3 to sinter the silicon particles constituting the green silicon particle layer 2, and thereby form a sintered silicon particle layer 5.
