Sheet resistance - Wikipedia

Sheet resistance, is a measure of resistance of thin films that are nominally uniform in thickness. It is commonly used to characterize materials made by semiconductor doping, metal deposition, resistive paste printing, and glass coating.Examples of these processes are: doped semiconductor regions (e.g., silicon or polysilicon), and the resistors that are screen printed onto the substrates of ...

Nu-FLOW | RIBUS

Nu-FLOW ® is made from rice hulls that are sterilized and ground to a fine powder. The unique functionality comes from the fact that 'Mother Nature' causes the rice plant to take up silica from the soil and concentrate it in the hulls of the rice, thereby producing a natural alternative to silicon dioxide or other anti-caking/flow agents.

Silicone rubber - Wikipedia

Silicone rubber is an elastomer (rubber-like material) composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen.Silicone rubbers are widely used in industry, and there are multiple formulations. Silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost.

4 flow that is important: 400sccm 5%SiH 4/N 2 = 20sccm SiH 4 + 380 sccm N 2 So you will need to flow 1000sccm 2%SiH 4/N 2 to achieve the same SiH 4 flow. The effect of the additional N 2 flow will be minimal, and can sometimes be compensated for by reducing the separate N 2 MFC flow (if applicable).
