• CMOS transistors are fabricated on silicon wafer • Lithography process similar to printing press • On each step, different materials are deposited or etched • Easiest to understand by viewing both top and cross-section of wafer in a simplified manufacturing process
1. The wafer is baked at 100°C to solidify the resist on the wafer. 2. The reticle is placed on the wafer and aligned by computer control. 3. The reticle is exposed to ultraviolet light with the transparent parts of the reticle passing the light onto the wafer. The photoresist under the opaque regions

The semiconductor manufacturing process begins with one of the most common elements on earth, silicon. Silicon is found in abundance in sand, but before it is used in semiconductor manufacturing it is refined to be virtually pure. Purity of materials is fundamental to delivering chips that function as …
Semiconductor device fabrication is the process used to create the integrated circuits that are present in everyday electrical and electronic devices. It is a multiple-step sequence of photo lithographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconducting material.
Manufacturing a Silicon Wafer Growing a silicon ingot can take anywhere from one week to one month, depending on many factors, including size, quality and the specification. More than 75% of all single crystal silicon wafers grow via the Czochralski (CZ) method.

PV manufacturing includes three distinct processes: 1. Manufacturing silicon (polysilicon or solar-grade), 2. wafers (mono- or polycrystalline) and 3. cells and modules (crystalline and thin-film).
of the wafer stage with nm accuracy is necessary and control of temperature for the bake process is very important. In RTP, precise control of temperature is a must. Control of pressure, temperature, and flow is ubiquitous. Robotics (wafer handling) is omnipresent in the fab. The semiconductor manufacturing process flow, when
Newer wafers (8" and 12") now use a groove to mark the orientation, instead of a cut to save some area for test structures. Manufacturers Data of incoming wafers: orientation, thickness, doping type, resistivity. Wafer Flat Wafer flats in 4" and 6" silicon wafers
