The original idea of this kind of shape is the same as the one reported by Puers et al. for the design of square shape compensation pattern for the formation of convex corners on Si{100} [91].
In the absence of compensation pattern, the beveled shape (or undercut shape) at obtuse and acute angles are shown by red and yellow color lines, respectively.
The evolving etched profile of compensation pattern clearly indicates that the significant beveling will take place at the convex corners A and B. This beveling can be reduced if the square shape compensation geometry (Figure 41(a)) is replaced by asymmetric <110> beams as illustrated in Figure 41(b).
More importantly, behind the scenes, compensation structures shape a large portion of deals, even when neither the buyer nor the seller's employer benefits.
In this case, a square whose center coincides with the apex of the convex corner is used for the time delayed etching to protect the convex corner [24,88,89,91,120,122,125]. It can be noticed from Figure 25 that the square shape compensation design contains three convex corner (m, n and T) and therefore this structure is consumed by the undercutting that starts from these corners.
Numerical dispersion compensation and Gaussian shaping was performed, and fixed pattern noise was removed [ 43].

The length of the sides of the compensating triangle (i.e. AP or AC ) can be determined using the law of sines (or sine rule) as follows: Figure 22 Schematic representation of triangular shape compensation geometry.
Similar to triangular shape compensation, further etching to remove the extra mass at convex corner alters the desired shape of the corner as shown in Figure 27(c).
Global payments might be brought to urban areas by defining the population each hospital must serve and shaping compensation schemes for patients who are treated elsewhere.
