    Abstract: The disclosure relates to a method for manufacturing a planarized etch-stop layer, ESL, for a hydrofluoric acid, HF, vapor phase etching process. The method includes providing a first planarized layer on top of a surface of a substrate, the first planarized layer having a patterned and structured metallic material and a filling material. The method further includes comprises depositing on top of the first planarized layer the planarized ESL of an ESL material with low HF etch rate, wherein the planarized ESL has a low surface roughness and a thickness of less than 150 nm, in particular of less than 100 nm.

    Abstract: A method for manufacturing an optical sensor is provided. The method comprises providing an optical sensor arrangement which comprises at least two optical sensor elements on a carrier, where the optical sensor arrangement comprises a light entrance surface at the side of the optical sensor elements facing away from the carrier. The method further comprises forming a trench between two optical sensor elements in a vertical direction which is perpendicular to the main plane of extension of the carrier, where the trench extends from the light entrance surface of the sensor arrangement at least to the carrier. Moreover, the method comprises coating the trench with an opaque material, forming electrical contacts for the at least two optical sensor elements on a back side of the carrier facing away from the optical sensor elements, and forming at least one optical sensor by dicing the optical sensor arrangement along the trench. Each optical sensor comprises an optical sensor element, and the light entrance surface is free of electrical contacts and at least partially free of the opaque material above the optical sensor elements. Furthermore, an optical sensor is provided.

    Abstract: A relief structure is formed on a surface of a carrier provided for accommodating a wafer, which is fastened to the carrier by a removable adhesive contacting the carrier. The relief structure, which may be spatially confined to the centre of the carrier, reduces the strength of adhesion between the wafer and the carrier. If the adhesive is appropriately selected and maintains the connection between the wafer and the carrier at elevated temperatures, further process steps can be performed at temperatures of typically 300° C. or more. The subsequent mechanical separation of the adhesive joint is facilitated by the relief structure on the carrier.

    Abstract: An intermetal dielectric and metal layers embedded in the intermetal dielectric are arranged on a substrate of semiconductor material. A via hole is formed in the substrate, and a metallization contacting a contact area of one of the metal layers is applied in the via hole. The metallization, the metal layer comprising the contact area and the intermetal dielectric are partially removed at the bottom of the via hole in order to form a hole penetrating the intermetal dielectric and extending the via hole. A continuous passivation is arranged on sidewalls within the via hole and the hole, and the metallization contacts the contact area around the hole. Thus the presence of a thin membrane of layers, which is usually formed at the bottom of a hollow through-substrate via, is avoided.

    Abstract: A semiconductor device has a semiconductor substrate and a first metallization stack arranged on the substrate. The substrate has and/or carries a plurality of electronic circuit elements. The first metallization stack has electrically insulating layers and at least one metallization layer. The semiconductor device further has a second metallization stack arranged on the first metallization stack and comprising further electrically insulating layers and an optical waveguide layer. The optical waveguide layer has at least one optical waveguide structure. Furthermore, one of the electrically insulating layers and one of the further electrically insulating layers are in direct contact with each other and form a pair of directly bonded layers.

    Abstract: The semiconductor device comprises a substrate (1) of semiconductor material, a dielectric layer (2) above the substrate, a waveguide (3) arranged in the dielectric layer, and a mirror region (4) arranged on a surface of a mirror support (5) integrated on the substrate. A mirror is thus formed facing the waveguide. The surface of the mirror support and hence the mirror are inclined with respect to the waveguide.
