1. What is the primary purpose of semiconductor fabrication technician
training programs in Maryland?
A. To certify professionals for advanced medical laboratory diagnostics
B. To prepare individuals for roles in chip manufacturing, cleanroom
operations, and process control
C. To train engineers exclusively for semiconductor design and circuit
architecture
D. To license workers for electrical power grid maintenance operations
Answer: B
Semiconductor fabrication technician programs are designed to
prepare individuals for hands-on roles in manufacturing
environments such as wafer processing, equipment operation,
cleanroom procedures, and quality control within semiconductor
production facilities.
2. Which of the following best describes semiconductor fabrication work
environments?
A. Open-air industrial workshops with general mechanical tools
B. Hospital sterile environments for biomedical device assembly
C. Controlled cleanrooms with strict contamination and particle
, control standards
D. Outdoor construction sites for infrastructure development
Answer: C
Semiconductor fabrication occurs in highly controlled cleanroom
environments where air purity, temperature, humidity, and
contamination levels are strictly regulated to prevent defects in
microchip production.
3. A key responsibility of semiconductor technicians in wafer fabrication
is:
A. Performing financial audits of production companies
B. Operating lithography, etching, deposition, and inspection
equipment
C. Designing integrated circuit architecture using CAD software only
D. Managing retail distribution of finished electronics
Answer: B
Technicians in semiconductor fabs typically operate and monitor
specialized tools used in wafer processing such as deposition
systems, etchers, and lithography machines to ensure proper device
fabrication.
4. What is the main function of photolithography in semiconductor
manufacturing?
A. To dissolve metal layers using chemical solvents
B. To transfer circuit patterns onto a wafer using light-sensitive
materials
C. To test finished chips for electrical failures
D. To assemble packaged electronic devices into consumer products
Answer: B
Photolithography uses light exposure through masks to transfer
intricate circuit patterns onto photoresist-coated wafers, forming the
foundation of integrated circuit design.
5. Which material is most commonly used as the base substrate in
semiconductor fabrication?
A. Aluminum
B. Copper
C. Silicon
, D. Gold
Answer: C
Silicon is widely used due to its semiconducting properties,
abundance, and ability to form stable oxide layers essential for
microelectronics manufacturing.
6. What does a cleanroom classification primarily measure?
A. Electrical conductivity of materials
B. Number of particles per volume of air
C. Speed of production machinery
D. Temperature of wafer surfaces only
Answer: B
Cleanroom classifications are based on allowable airborne particle
concentrations, which directly affect the quality and yield of
semiconductor devices.
7. Which process removes excess material from a wafer using chemicals
or plasma?
A. Doping
B. Etching
C. Packaging
D. Soldering
Answer: B
Etching is used to selectively remove material from wafer surfaces,
often using chemical or plasma processes to define circuit structures.
8. What is the purpose of doping in semiconductor fabrication?
A. To physically polish wafer surfaces
B. To introduce impurities that modify electrical properties
C. To package chips for shipment
D. To measure wafer thickness
Answer: B
Doping introduces controlled impurities into silicon to alter its
conductivity, enabling the creation of p-type and n-type
semiconductor regions.
9. Which quality control method is commonly used in semiconductor
manufacturing?
A. Statistical Process Control (SPC)
