Interactive Activity 1Online version Read the clues and then look at the answer to see if you were correct. by Josselyn Jeaneth Martinez Tobar 1 I'm a foundational device in modern technology, operating as a voltage-controlled switch or for signal amplification. I'm at the heart of microprocessors and memory chips. What am I? 2 I'm a process used to introduce impurity atoms into a semiconductor to change its electrical properties. I can be achieved through ion implantation. What am I? 3 I'm a highly specialized manufacturing facility where intricate and multi-layered wafer processing occurs. I can take 16 to 18 weeks to complete a single wafer. What am I? 4 I'm a foundational electronic device that allows current to flow in one direction but largely blocks it in the other. I'm used in power supplies to convert alternating current to direct current. What am I? 5 I'm a special class of materials whose electrical conductivity is between that of a conductor and an insulator. My properties are changed by a process called doping. What am I? 6 I'm a manufacturing technique that transfers intricate patterns from a photomask onto a silicon wafer. This process is essential for forming the three-dimensional components of a circuit. What am I? 7 I'm a small, flat-screen device that uses thin films of organic compounds that emit light when an electrical current is passed through them. I'm used in many mobile devices. What am I?
