Web1.1 WAFER FABRICATION (FRONT-END) Identical integrated circuits, called die, are made on each wafer in a multi-step process. Each step adds a new layer to the wafer or modifies the existing one. These layers form the ele-ments of the individual electronic circuits. The main steps for the fabrication of a die are summarized in the following table.

WebApr 6, 2024 · Step 2. Slicing Ingots to Create Thin Wafers. Ingots, shaped like a spinning top, are sliced into thin, disc-shaped wafers of uniform thickness using sharp diamond saw blades. The diameter of an ingot determines the size of a wafer, such as 150 mm (6 inch), 200 mm (8 inch), and 300 mm (12 inch) wafers. interventional echocardiographer
