Therefore, we have to control μpre and σ pre 2 considering the amount of μshift and σ shift 2. Basically, μpre and σ pre 2 can be controlled by verify levels and the incremental step size ΔV pp of ISPP though physical mechanisms such as cell-to-cell interference, program disturbance, and background pattern dependency also affect μpre and σ pre 2 [5, 7, 8].
One of the most important issues for performance of MOSFETs is integrity of SiGe SEG in terms of layer quality, selectivity, surface roughness, and strain amount and pattern dependency [2].
A test pattern was designed with a series of grouped chips to calibrate the pattern dependency of SEG (both growth rate and Ge content).
The pattern dependency of SEG is referred to the situation when the layer profile (composition and layer thickness) is dependent to the pattern layout (density and size of oxide openings) and architecture (oxide or nitride) of Si wafer [20 23].
Pattern dependency of selective epitaxy of Si1−xGex (0.20 ⩽ x ⩽ 0.45) grown in recessed source/drain regions of 22 nm pMOSFETs has been studied.
In this part, more attention is paid to selective epitaxy of SiGe where the pattern dependency behavior may result in strain variation within a chip or from chip to chip because of layout changes over processed wafers.
A good outcome of high HCl partial pressure during epitaxy is a better control of pattern dependency of the growth [24, 25].
Information was systematically analyzed to identify patterns, dependencies, connections, and causal factors.
The different cellular markers for both apoptosis and necrosis followed a similar pattern of dose dependency and indicated a heterogenic cell population with regard to leukotoxin sensitivity.
Emerging patterns of alcohol dependency and needs for prescription medication among TFA CMs are not invitations to collectively try harder or press further into the narrative that exacts these costs.
