1. Technology Education THE PERSONAL COMPUTER (PC) HARDWARE PART 7

2. Purpose Of Lesson Part 7
Learn how this marvel called an Integrated Circuit (IC) is designed, manufactured, and how it works.

3. VOCABULARY FOR THIS LESSON
CONDUCTOR
INSULATOR
TRANSISTOR
SEMICONDUCTOR.
SUPERCONDUCTOR
CLEAN ROOM
PHOTOLITHOGRAPHY

4. CONDUCTOR
ANY MATERIAL THAT CAN CONDUCT (CARRY) ELECTRONS (ELECTRICITY).
CAN YOU NAME SOME?

5. INSULATOR
ANY MATERIAL THAT STOPS THE FLOW OF ELECTRONS.

6. TRANSISTORS TWO TYPES NPN AND PNP.
CAN STOP OR START THAT FLOW OF ELECTRONS.
CAN BOOST THE FLOW OF ELECTRONS.

7. SEMICONDUCTOR ON SEMICONDUCTOR IS SILICON
SILICON IS THE MOST ABUNDANT ELEMENT IN THE EARTH’S CRUST
BASICALLY GLASS
CAN EITHER CONDUCT OR INSULATE DEPENDING ON HOW ITS TREATED!

8. SUPERCONDUCTORS CONDUCT ELECTRONS WITHOUT LOSING ANY!!
NO HEAT GIVEN OFF!!!
ALL THAT WE HAVE ARE ONES THAT WORK WHILE VERY COLD!!!

9. SUPERCONDUCTORS
Scientist are looking for a room temperature superconductor for years now with no luck.
If they find one it will revolutionize the WORLD AS WE KNOW IT!!!!
Superconductors also exhibit almost magical properties!

10. CLEAN ROOM
ROOM THAT IS KEPT 100,000 TIMES CLEANER THAN AN OPERATION ROOM. COST BILLIONS OF DOLLARS TO BUILD ROOMS THIS CLEAN!!!!!

11. PHOTOLITHOGRAPHY
USING LIGHT TO PRINT THINGS DOWN TO JUST A COUPLE DOZEN MICRONS WIDE!!!

12. WE HAVE DISCUSSED CONDUCTOR INSULATOR TRANSISTOR SEMICONDUCTOR.
SUPERCONDUCTOR
CLEAN ROOM
PHOTOLITHOGRAPHY
