As DRAM technologies scale to increasingly tighter pitches, the patterning requirements exceed the limits of conventional single-exposure DUV lithography. In advanced nodes such as D1b (1-beta), ...
Dynamic random-access memory (DRAM) chips contain many other transistors besides the access transistor to enable full operation of the DRAM memory. These peripheral transistors must meet stringent ...
Process and device technologies have had to overcome numerous technical challenges as DRAM memory devices have transitioned between different cell architectures. When DRAM technology nodes went beyond ...
