    摘要: Surface mount semiconductor devices and methods for fabricating surface mount semiconductor devices are disclosed. In particular, back-contact-only multijunction photovoltaic cells and the process flows for making such cells are disclosed. The surface mount multijunction photovoltaic cells include through- wafer- vias for interconnecting the front surface epitaxial layer to a contact pad on the back surface. Before etching the through- wafer-vias the substrate is thinned to less than 150 μm. The through-wafer-vias are formed using a wet etch process that removes semiconductor materials non-selectively without major differences in etch rates between heteroepitaxial III-V semiconductor layers. Low stress passivation layers are used to reduce the thermo-mechanical stress of the semiconductor devices.

The first doped region (3) extends to a first surface (11) in the via hole (2). The second doped region (5) is present at the second side (1b) of the substrate (1) and is suitably formed by ion implantation. The resulting solar cell has an appropriate isolation between first doped region (3) and second doped region (5) over a second surface (12) in the via hole (2) and is suitably provided with a deep junction between the first doped region (3) and dopant in the substrate (1).
