gs0202.001&tf&2&N&Silicon is a semiconductor material.&TRUE&FALSE&&&&&undefined.0&&&&&4&&&N.
gs0202.002&tf&0&N&The process of etching components on chips is called photosynthesis.&FALSE&TRUE&The process of etching components on chips is called photolythography.&&&&undefined.0&&&&&1&&&N.
gs0202.003&tf&0&N&Clean rooms are used when manufacturing chips to keep impurities out of the production process.&TRUE&FALSE&In a clean room, air is continuously filtered to remove contaminants, and temperature, humidity, and barometric pressure are also closely controlled.&&&&undefined.0&&&&&1&&&N.
gs0202.004&mcs&0&&What is the most common way of improving a chip's performance?&Place more components on the chip.&Use less corrosive chemicals for doping.;Use a purer silicon crystal.;&Performance gains are achieved by placing more components on a chip, which increases the chip's density. The chip performs faster because the electrons have less distance to cover.<br>&&&x&undefined.0&&&&&1&&&N.
gs0202.005&tf&0&&Moore's law is really not a scientific law, but an observation.&TRUE&FALSE&Moore originally predicted that chip components would double every 18 months. This trend has since been called Moore's Law, although it's really just an observation by Gordon Moore.<br>&&&&undefined.0&&&&&1&&&N.
gs0202.006&mcs&0&&What did IBM announce it could use instead of aluminum when developing computer chips?&Copper&Bi-polar;Pentium;&Instead of attempting to drive subtractive-aluminum wiring beyond its reasonable limits, IBM made a breakthrough to employ an additive-copper, dual-damascene wiring process for its high-performance CMOS chips.&&&x&undefined.0&&&&&1&&&N.
