Chapter 1 Intro Flashcards
Infrastructure
Industry Standards, production tools, utilities, materials & chemicals, metrology tools, analytical laboratories, technical workforce, college & universities.
Product Applications
Consumers; (Computers, automotive, aerospace, medical, other, industries), Customer service, original equipment manufacturers, printed circuit board industry.
Advantages of Solid State
Minuscule size, no vacuum, reliable, lightweight, minimal heat production, and low power consumption.
Wafer
A single integrated circuit, also known as a die, chip, and microchip.
Five Stages of IC Fabrication
- Wafer preparation
- Wafer fabrication
- Test/Sort
- Assembly/Package
- Final Test
Wafer Preparation
Growing crystal, rounding, slicing, and polishing.
Wafer fabrication
Cleaning, layering, patterning, etching, and doping.
Test/Sort
Probing, testing, and sorting.
Assembly/Package
Scribe lines to separate. Metal corrections are made and the chip is encapsulated.
Final Test
Passes electrical and environment testing.
Semiconductor Trends
- Increase in chip performance.
- Increase in chip reliability.
- Reduction in chip price.
The Clean Room
Are specially designed areas with low contamination. Air is constantly being filtered and recirculated. Turbulent or Directional.
Turbulent: Non-Direcional
Pushes air/particles to the floor and into filters.
Turbulent: Directional
That pushes air/particles towards the filters/intake.
How many particles can stationary human produce compared to moving one?
A stationary human can produce 100,000 particles per minute and moving human can produce 1,000,000.
