The hemispherical grain silicon formation technique has a silicon layer (40) onto which is placed a layer of hemispherical granular silicon (42). A second layer of hemispherical grain silicon is formed on top of the first granular layer, such that independent grains of the second silicon layer are formed on top of the first layer. The structure forms the lower capacitor electrode.

The method involves determining the relationship between an image gathered by an aircraft and a cartographic region in two different Cartesian co-ordinate systems and calculating a transform matrix. The transform matrix is calculated by determining coefficients by solving a set of equations. The transform matrix is used to express in the coincident co-ordinate system the direction of the projectio...
