Basic Principles and Applications of Semiconductor Technology (2026) (Leaving Cert Engineering): Flashcards

High sensitivity to ambient temperature changes affecting performance

Performance shifts, reduced reliability, need for compensation

High manufacturing costs due to complex fabrication requirements

Maintain ultra-pure environments free from contamination

Max operating temps before performance degrades or device fails

Increased temp → increased current → more heat, cycle continues

Performance depends critically on semiconductor material purity

Even a single dust particle can destroy an entire wafer

Devices degrade over time, affecting reliability & performance

Metal conductors gradually wear away under electrical stress

Damage the semiconductor material over time during operation

Substantial initial investment costs for manufacturing facilities
