IEC 63011-3:2018

Overview

IEC 63011-3:2018 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies a reference model and measurement conditions for the through-silicon via (TSV) - a critical technology in three-dimensional integrated circuits (3-D ICs). This part of the IEC 63011 series focuses on defining the electrical characteristics required for TSVs to ensure reliable transmission and reception of digital data in multi-chip 3-D IC implementations. The document details standardized methods for measuring TSV resistance and capacitance, vital for consistency and interoperability in digital consumer and mobile applications. Power devices, RF devices, and micro-electromechanical systems (MEMS) are explicitly excluded from its scope.

Key Topics

• Through-Silicon Via Reference Model:
  The standard introduces a reference circuit model for the electrical characterization of TSVs, including considerations for capacitance and resistance. The model supports the interface design needed for digital data transmission in 3-D integrated circuits.

• Measurement Conditions:
  IEC 63011-3:2018 establishes the measurement procedures and conditions for:

  • TSV resistance (using four-point measurement to isolate the resistance of the TSV from the surrounding structures).
  • TSV capacitance (impedance measurement to distinguish TSV capacitance from parasitic capacitances).
  • Frequency and voltage dependence of the TSV's electrical characteristics.

• Scope and Exclusions:
  The standard is specifically tailored to digital consumer and mobile electronics, covering operating voltages from 0.1 V to 5 V and frequencies below 2 GHz. It excludes power devices, RF devices, and MEMS from its requirements.

• Model Standardization Policy:

  • Resistance is defined as an average value.
  • Capacitance is waveform-defined, and fringe capacitance is removable.
  • Inductance is not considered due to minimal influence.
  • The model assumes the semiconductor substrate is connected to ground.

Applications

IEC 63011-3:2018 is highly relevant to manufacturers, designers, and test engineers working with advanced digital devices that leverage 3-D IC stacking. Key applications include:

• Multi-Chip Module (MCM) Design:
  Enables accurate modeling and interface development for high-density multi-chip solutions, particularly in mobile phones, digital cameras, and tablets.

• System on Chip (SoC) Integration:
  Facilitates the integration of heterogeneous technologies, allowing digital logic and memory to interface efficiently and reliably through standardized TSV designs.

• Quality Assurance & Testing:
  Standardizes the performance measurement criteria, supporting consistent TSV characterization across the semiconductor industry. Ensures reliable high-speed, low-power interconnection essential in modern consumer electronics.

• Design for Manufacturability:
  Provides guidelines that help in mitigating the effects of mechanical stress and maintain transistor reliability near TSV structures (keep-out zones).
