Viable Method

Abstract Body effect is the key characteristic of DRAM cell transistor. Conventional method uses a TEG structure for body effect measurement. But this measurement is not accurate, because TEG structure has only several transistors and it is located outside of the DRAM die. This paper suggests a viable method for measuring DRAM cell transistor body effect. It uses a memory test system for fast, massive, nondestructive measurement. Newly developed method can measure 100,000 DRAM cell body effects in two minute, without sample damage. The test gives one median value and 100,000 individual values of body effects. Median value of measured body effects is equal to the TEG body effect. An individual DRAM cell body effect has a correlation with the fin height.

Interdot Coupling

In this paper, several four-quantum-dot topological structures are designed. The influence of the interdot coupling strength and intradot Coulomb interactions on the conductance is discussed. The location of the anti-resonance band can be manipulated by tuning the interdot coupling strength, which suggests a physical scheme of an effective quantum switch. The Fano anti-resonance peak may evolve into a resonance peak. For the particular value of the interdot coupling strength, two Fano anti-resonances collapse and bound states in the continuum are formed. Moreover, many-body effect makes the number of anti-resonance bands increase. This study provides a theoretical basis for the design of quantum computing devices.
