A method of implanting an implant species into a substrate at different depths is described. The method includes forming an implant mask over the substrate. The implant mask includes a first implant zone designed as an opening and a second implant zone designed as a block array. The implant species is implanted through the implant mask under an implant angle tilted against a block plane, such that a first implant area is formed by the implant species at a first depth in the substrate beneath the first implant zone and a second implant area is formed by the implant species at a second depth in the substrate beneath the second implant zone. The first depth is greater than the second depth.

An exposure method includes projecting a reticle pattern into a first exposure field of a photoresist layer, wherein the reticle pattern includes first and second line patterns on opposite edges of the reticle pattern and wherein at least the first line pattern includes an end section through which light flux decreases outwards. The reticle pattern is further projected into a second exposure field of the photoresist layer, wherein a first tapering projection zone of the end section of the first line pattern in the second exposure field overlaps a projection area of the second line pattern in the first exposure field.

A method of dicing a wafer includes providing a wafer and etching the wafer to singulate die between kerf line segments defined within an interior region of the wafer and to singulate a plurality of wafer edge areas between the kerf line segments and a circumferential edge of the wafer. Each one of the plurality of wafer edge areas is singulated by kerf lines that each extend between one of two endpoints of one of the kerf line segments and the circumferential edge of the wafer.

A semiconductor device includes a central portion and an edge termination portion outside the central portion. The central portion includes a transistor cell array in a semiconductor substrate. Components of transistor cells of the transistor cell array are disposed in adjacent trench structures in the semiconductor substrate. The trench structures run in a first linear direction parallel to a main surface of the semiconductor substrate. The trench structures include a plurality of concatenated trench segments in a plane parallel to the main surface in the central portion, at least one of the trench segments connecting a first point and a second point of one trench structure, the first point and the second point being arranged along the first linear direction. The trench segment comprises a portion extending in a direction different from the first direction.

A semiconductor component comprises a semiconductor body with at least one protective trench in the semiconductor body. An insulation layer is situated at least at the bottom of the protective trench. An electrically conductive layer having a thickness D is formed on the insulation layer in the protective trench, wherein the electrically conductive layer only partly fills the protective trench.
