Abstract:
1. A method for producing a semiconductor device, comprising: producing a semiconductor wafer with semiconductor device positions arranged in rows and columns for semiconductor devices in flip-chip technology with contact areas on an active top side including flip-chip contacts; applying an electrically insulating layer as underfill material to the active top side of the semiconductor wafer while covering the flip-chip contacts, the electrically insulating layer comprising a UV B-stageable material; applying a patterned mask on the active top side of the semiconductor wafer; exposing the mask by means of UV radiation, so that the flip-chip contacts are not exposed and at least a surface of the exposed regions is brought to a cured intermediate state; removing the unexposed regions of the layer while leaving free at least a tip of the flip-chip contacts; and separating the semiconductor wafer into individual semiconductor devices.
