The invention provides a vertical surface emitting type laser structure and a production method. In the vertical surface emitting type laser structure, a light emergent direction is a P-surface lightemergent direction, and a heat dissipation direction is opposite to the light emergent direction, so that heat dissipation is not depended on a substrate structure, which is beneficial to high-efficiency heat dissipation; and moreover, a P electrode and an N electrode are positioned on the same side, and by arranging an N-type welding pad and a P-type welding pad, an electrode routing structure isnot required so as to reduce a packaging volume to a great degree. 本发明提供了一种垂直面射型的激光结构及制作方法，该垂直面射型的激光结构中，其出光方向为P面出光，散热方向与出光方向相反，以使散热不再通过衬底结构，有助于高效率散热；并且，P电极和N电极位于同侧，通过设置N型焊垫和所述P型焊垫，不再需要电极打线结构，进而极大程度的缩小了封装体积。
