1. Semiconductor Fundamentals and the Importance of Temperature Control

1.1 What is a Semiconductor

Semiconductor material definition: Materials with electrical conductivity between conductors and insulators, with resistivity in a specific range at room temperature. The main characteristic is that their conductivity can be controlled through temperature, liwanag, mga magnetic field, or doping concentration.

Main semiconductor material types:

Single crystal silicon (Si): Accounts for the vast majority of the global semiconductor market, with certain operating temperature limitations
Gallium arsenide (GaAs): High-frequency and high-speed applications, electron mobility far exceeds silicon
Silicon carbide (SiC): Third-generation semiconductor, can operate in extremely high temperature environments
Gallium nitride (GaN): High power density applications, excellent breakdown field strength

Core applications of semiconductors in modern industry:

Integrated circuit chips (CPU, GPU, memory)
Power electronic devices (IGBT, MOSFET, diodes)
Optoelectronic devices (LED, mga laser, mga photodetector)
Mga sensor (temperatura, presyon, acceleration, image sensors)

1.2 Why Semiconductors Need Precise Temperature Measurement

The impact of temperature on semiconductor physical properties is extremely significant. Intrinsic carrier concentration has an exponential relationship with temperature, and temperature changes in silicon materials have a huge impact on intrinsic carrier concentration. This directly affects key parameters such as on-resistance, threshold voltage, and leakage current of devices.

Temperature control requirements in semiconductor manufacturing processes:

Rapid Thermal Processing (RTP): Requires extremely high temperature accuracy and rapid heating capability
Chemical Vapor Deposition (CVD): Strict temperature uniformity requirements, needs long-term stability
Diffusion/oxidation processes: Precise temperature control, multi-zone independent temperature control
Lithography baking: Temperature stability directly affects photoresist sensitivity

Power semiconductor thermal management challenges are becoming increasingly severe. Moderno IGBT modules have extremely high power density, at SiC MOSFETs can reach very high operating junction temperatures. Local hot spot temperatures may far exceed average temperatures, becoming the main cause of device failure.

1.3 Common Semiconductor Failure Analysis

Thermal-related failure mechanisms account for a major portion of semiconductor failures:

Hot Carrier Injection (HCI): Sa mataas na temperatura, carriers gain enough energy to inject into the gate oxide layer, causing threshold voltage drift. Temperature increases significantly accelerate HCI degradation rates.

Electromigration phenomenon: Atoms in metal interconnects undergo directional migration under the influence of current and temperature, forming voids or hillocks. Following Black’s equation, lifetime has an exponential inverse relationship with temperature.

Thermal mechanical stress failure: Stress concentration caused by differences in thermal expansion coefficients of different materials. The thermal expansion coefficients of silicon and copper differ greatly, and temperature cycling leads to solder joint fatigue cracking.

Bond wire failure: Power cycling causes cracks at the interface between aluminum wires and chips, contact resistance increases, local temperature rise intensifies, forming positive feedback failure.
