Abstract
Official abstract text for this publication.
A mask read only memory containing diodes and method of manufacturing the same. The mask read only memory is a high-density three dimensional array formed by stacking a plurality of diode layers and the logic “0” or “1” is defined by whether there is a dielectric layer on the diode.
First claim
Opening claim text (preview).
What is claimed is: 1. A mask read only memory containing diodes, comprising: a semiconductor substrate; an insulating layer on the semiconductor substrate; at least two memory cell layers stacked on the insulating layer, each memory cell layer including: a first conductive line along a first direction on the insulating layer; a vertical diode on the first conductive line; a dielectric layer on the vertical diode; and a second conductive line along a second direction on…
