Abstract: Embodiments provide a photodiode having two electrodes and an absorption volume for absorbing photons, wherein the absorption volume has a photon entry area, wherein the two electrodes are configured to generate an electric field in an active region between the two electrodes when a reverse voltage is applied, wherein the electric field runs parallel to the photon entry area, wherein, starting from a surface of a semiconductor substrate of the photodiode, the two electrodes essentially extend orthogonally to the surface in a depth direction of the semiconductor substrate, wherein the photodiode has at least one guard structure formed in the semiconductor substrate that is disposed below at least one of the at least two electrodes.

Abstract: The concept relates to a method for producing a three-dimensionally integrated semiconductor memory. A layer stack having several individual layers of different material types is provided and individual layers of a first material type are etched out selectively from the layer stack by a dry etching process. Individual layers of a third material type are generated either by filling voids with a third material or converting the individual layers of the second material type into the individual layers of the third material type, or by coating the individual layers of the second material type with a material of the third material type. Voids between the individual layers of the third material type can then again be filled with a fourth material, such that individual layers of a fourth material type are formed in these voids.

Abstract: A transistor structure includes a first terminal region, a second terminal region and a channel region therebetween in a semiconductor substrate. Additionally, the transistor structure includes a control electrode associated with the channel region, the control electrode having a control electrode portion which is elastically deflectable under the action of a force and spaced apart from the channel region. The distance between the control electrode portion and the channel region is changed based on the action of force.
