Abstract:
1. A method of manufacturing a base for a light emitting device, comprising steps of: providing a substrate having a first surface and a second surface; forming a first mask layer and a second mask layer on said first surface and said second surface respectively; forming a first opening and a second opening on said first mask layer and said second mask layer respectively; wherein said first opening is larger than said second opening; executing an etching on said substrate under a specified condition for forming a holding space on said first opening and at least one through hole on said second opening, wherein the top of said at least one through hole is connected to the bottom of said holding space to form a junction having a sharp edge; and continuously executing said etching on said substrate under said specified condition so as to remove said sharp edge of said junction to form at least one inclined surface which is configured to exhibit a function of preventing a fault of a conductive layer to be applied onto said substrate subsequently, wherein said second surface includes a solder stop structure formed by steps of: defining a third opening on said second mask layer formed on said second surface of said substrate; and etching said substrate under a specified condition on said third opening so as to remove a part of material of said substrate to form said solder stop structure.
