摘要： A nonvolatile integrated semiconductor memory has an arrangement of layers with a tunnel barrier layer and a charge-storing level. The charge-storing level has a dielectric material which stores scattered in charge carriers in a spatially fixed position. The tunnel barrier layer has a material through which high-energy charge carriers can tunnel. At least one interface surface of the charge-storing level has a greater microscopic roughness than the interface surface of the tunnel barrier layer, which is remote from the charge-storing level. The charge-storing level has a greater layer thickness in first regions than in second regions. This produces a relatively identical distribution and localization of positive and negative charge carriers in the lateral direction. The charge carriers which are scattered into the charge-storing level, therefore, recombine completely, so that the risk of unforeseen data loss during long-term operation of nonvolatile memories is reduced.
摘要翻译：非易失性集成半导体存储器具有具有隧道势垒层和电荷存储电平的层的排列。电荷储存电平具有在空间固定位置中分散存储在电荷载体中的电介质材料。隧道势垒层具有高能电荷载流子穿过的材料。电荷存储水平的至少一个界面表面具有比远离电荷存储水平的隧道势垒层的界面更大的微观粗糙度。电荷存储水平在第一区域中具有比在第二区域中更大的层厚度。这在横向方向产生正电荷载体和负电荷载体的相对相同的分布和定位。因此，分散到电荷存储电平的电荷载体完全复合，从而降低了在非易失性存储器的长期操作期间不可预见的数据丢失的风险。

摘要： The storage layer (6) is in each case present above a region in which the channel region (3) adjoins a source/drain region (2) and is in each case interrupted above an intervening middle part of the channel region (3). The storage layer (6) is formed by material of the gate dielectric (4) and contains silicon or germanium nanocrystals or nanodots introduced through ion implantation. The gate electrode (5) is widened at the flanks by electrically conductive spacers (7).
