晶闸管随机存取内存
摘要：
本发明涉及晶闸管随机存取内存，其中，提出数种用以形成装置的装置及方法。该装置包括：有具第一极性类型之井区的衬底，以及基于晶闸管之记忆单元。该基于晶闸管之记忆单元包括：邻近该井区具第二极性类型之至少一第一区；设置于该衬底上用作为第二字线的栅极；具该第一极性类型之至少一第一层，其系设置成邻近具该第二极性类型之该第一区且邻近该栅极；以及具该第二极性类型之至少一重掺杂第一层，其系设置于具该第一极性类型之该第一层上且邻近该栅极。至少具该第二极性类型之该重掺杂第一层与该栅极的侧面自我对齐。
摘要（英）：

The invention relates to a thyristor random access memory. Devices and methods for forming a device are presented. The device includes a substrate having a well of a first polarity type and a thyristor-based memory cell. The thyristor-based memory cell includes at least a first region of a second polarity type adjacent to the well, a gate which serves as a second word line disposed on the substrate, at least a first layer of the first polarity type disposed adjacent to the first region of the second polarity type and adjacent to the gate, and at least a heavily doped first layer of the second polarity type disposed on the first layer of the first polarity type and adjacent to the gate. At least the heavily doped first layer of the second polarity type is self-aligned with side of the gate.
