    Dashed lines indicate the edges of original hexagonal shape mask pattern. The process starts with coating of positive photoresist on oxidized silicon wafer using spinning method. If the mask patterns are transferred in mask layer without any mask edge distortion i.

It can easily be noticed in Fig. Wet anisotropic etching, which is low cost and best suitable for batch process, is a well-established technique in silicon bulk micromachining [ 12345678 ]. Cancel Save. The dimensions of the proposed pre-etch pattern are presented in Fig.

    Introduction The basis for determining index values is the unit cell, with a right- handed coordinate system consisting of three x, y, and z axes situated at one of the corners and coinciding with the unit cell edges, as shown in figure.
