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.
摘要翻译：本发明提供半导体产品（25）和形成半导体产品（25）的方法，所述半导体产品（25）包括具有第一（11）和第二源/漏区（12）的晶体管（1）衬底（2）中凹部（R）的底表面（B）。由于凹陷（R）的深度（d），实现了源极/漏极区域（11,12）和栅极电介质（4）之间的垂直偏移（29）。垂直偏移（29）允许减小源极/漏极区域（11,12）和栅极电介质（4）之间的横向偏移（28）。因此，晶体管所需的衬底表面积减小。特别是在诸如存储器件的半导体产品的高电压区域中，更有效地使用衬底区域。
