Description
Die vorliegende Erfindung betrifft Halbleiter-DRAM-Speicher, und insbesondere einen Durchgangstransistor, der in einem DRAM-Speicherarray verwendet wird, der mit Arsen implantiert ist.The The present invention relates to semiconductor DRAM memories, and more particularly a pass transistor used in a DRAM memory array which is implanted with arsenic.
Dynamische Speicher mit wahlfreiem Zugriff (DRAM) werden nun üblicherweise in sämtlichen PC-Systemen (PC: Personalcomputer) eingesetzt. Ein DRAM besteht aus Millionen einzelner Speicherzellen, die in einem zweidimensionalen Array oder Feld angeordnet sind. Jede Speicherzelle weist einen Speicherkondensator zur Ladungsspeicherung auf. Das Vorhandensein bzw. die Abwesenheit von Ladung auf dem Speicherkondensator ist mit der dort gespeicherten digitalen Information korreliert. Weiterhin weist jede Speicherzelle einen Durchgangstransistor auf, der dazu eingesetzt wird, die Abtastung des Speicherkondensators durch einen Abtastverstärker zu ermöglichen. Der Durchgangstransistor wird auch als Zugriffstransistor bezeichnet.dynamic Random Access Memory (DRAM) is now becoming commonplace in all PC systems (PC: personal computer) used. A DRAM consists of millions single memory cells operating in a two-dimensional array or field are arranged. Each memory cell has a storage capacitor for charge storage. The presence or absence of charge on the storage capacitor is stored there with the correlated digital information. Furthermore, each memory cell a pass transistor used to scan the sample Storage capacitor through a sense amplifier to allow. The pass transistor becomes also referred to as access transistor.
