Abstract:
An optoelectronic semiconductor chip is disclosed. In an embodiment, the chip includes a semiconductor layer sequence with a first side, a second side and an active zone and at least one via electrically contacting the first side with the second side through the active zone, wherein the via has a base region including a cylinder, a truncated cone or a truncated pyramid, wherein the via is surrounded in a lateral direction by an electric insulation layer, wherein the via has a contact region including a truncated cone, a truncated pyramid, or a spherical or aspherical body, wherein the contract region directly follows the base region, wherein the contact region is in direct contact with the second side, wherein a first flank angle of the base region is different from a second flank angle of the contact region, and wherein the first and second flank angles are related to the lateral direction.

Claim (Index 27):
An optoelectronic semiconductor chip comprising:\n a semiconductor layer sequence comprising a first side, a second side and an active zone lying between the first side and the second side, wherein the two sides are of different conductivity types; and at least one via electrically contacting the first side with the second side through the active zone, wherein the via has a base region comprising a cylinder, a truncated cone or a truncated pyramid, wherein the base region is surrounded in a lateral direction, perpendicular to a growth direction of the semiconductor layer sequence, by an electric insulation layer, wherein the via has a contact region comprising a truncated cone, a truncated pyramid or a spherical or aspherical body, wherein the contact region directly follows the base region in a direction parallel to the growth direction, and wherein the contact region is in direct contact with the second side, wherein a first flank angle of the base region is larger than a second flank angle of the contact region by at least 3\u00b0 and by at most 25\u00b0, wherein the first and the second angles are related to the lateral direction so that the first flank angle is between 40\u00b0 and 70\u00b0 inclusively and the second flank angle is between 25\u00b0 and 55\u00b0 inclusively, and wherein the following applies to a height h of the contact region and to a mean diameter d 1  of the via at a boundary between the contact region and the base region: 7\u2264d 1 /h\u226420.
