Semiconductor device fabrication

These resins are used in various chemical instrumentation and medical devices due to their high solvent, heat, and flame resistance properties. These resins have a temperature limit of 340 °F. • Liquid Crystal Polymers: Abbreviated as LCP, these polymers exhibit high tensile strength, and have high heat and chemical resistance…

satisfied and costs down is a big challenge for high tech industries. Altera Corp., California-based chipmaker (Programmable Logic Devices - PLDs) recognized these challenges in-built in its industry hence it was forced to write-off their inventory stock totaling a mammoth $115 million dollars. Altera is a fabless chipmaker which outsources its chip wafers to Taiwan Semiconductor Manufacturing Corporation.…

Due to faster paced, more dynamic, and more complex market environment, ADI had to alter its scorecard accordingly in the late nineties. The major changes faced by ADI in mid-90’s are: • Because their products were at the heart of many Internet devices, such as PC modems and asynchronous digital subscriber line (ADSL) switches, the Internet boom drove much of ADI’s growth. Internet era let to a 78 % increase in top line growth • ADI’s new market had very different demand characteristics. •…

materials when there is a temperature difference applied between them is demonstrated. Usual thermoelectric system has a pair of n- and p-type semiconductor materials (thermocouple) for obtaining a large thermoelectromotive force. This effect can also be used to determine the temperature or change the temperature of matters. Therefore, thermoelectric devices can act as a good temperature controller. Hence, the direction of heating and cooling is determined by the polarity of the applied…

2.1 Silicon-Carbide (SiC) Initially, Silicon carbide (SiC) was accidentally introduced by Edward G. Acheson in 1890. Silicon Carbide can be stated as a chemical compound of Silicon and the carbon. Edward G. Acheson was running an experiment on the synthesis of diamonds. At that time, it was produced by a high temperature electro chemical reaction of sand and carbon. We can also find the silicon carbide very rarely in nature in very small amounts. Also Edward G. Acheson was the first person to…

How Electro-mechanical Actuator Works? A Rotary Electromechanical Actuation system with an Electric Motor, a gear box & an elastic spring to absorb peak torque loads experienced during operational life. The Schematic below describes the system. Fig. 1.1 Rotary Electro-mechanical Actuator Gearbox Requirements: The Gear Box at the Motor Output is intended to amplify the torque output of the Motor with reduction in speed. The tentative ratio is set at 10:1. Functional Requirements of…
