    摘要: The invention provides a semiconductor product (25) and a method for forming the semiconductor product (25), the semiconductor product (25) comprising a transistor (1) having first (11) and second source/drain regions (12) being arranged at bottom surfaces (B) of recesses (R) in a substrate (2). Due to the depth (d) of the recesses (R) a vertical offset (29) between the source/drain regions (11, 12) and a gate dielectric (4) is achieved. The vertical offset (29) allows reducing a lateral offset (28) between the source/drain regions (11, 12) and the gate dielectric (4). Thereby, the substrate surface area required for a transistor is reduced. In particular in high voltage areas of semiconductor products like memory devices, substrate area is used more efficiently.
