Trends
Technological trends in semiconductor plasma etching are continuously evolving to address the
growing demands of the semiconductor industry for higher performance, increased
functionality, and enhanced manufacturability. Several key trends are driving innovation in
plasma etching technologies:
Sub-Nanometer Feature Control: With the ongoing push towards smaller feature sizes and
higher device densities, there is a critical need for plasma etching techniques capable of
achieving sub-nanometer feature control. Advanced plasma sources, such as inductively
coupled plasma (ICP) and electron cyclotron resonance (ECR), enable precise control over ion
energy and flux, facilitating the etching of ultrafine features with sub-nanometer accuracy.

growing demand for plasma etching processes that offer high selectivity and compatibility with
diverse materials. Selective etching chemistries and process recipes enable the precise removal
of target materials while minimizing damage to underlying layers and interfaces, ensuring
optimal device performance and reliability.
Anisotropic Etching and Sidewall Control: Anisotropic etching, which produces vertical sidewalls
with minimal sidewall roughness, is essential for fabricating advanced semiconductor structures
with precise dimensions and profiles. Advanced plasma etching techniques, such as reactive ion
etching (RIE) and deep reactive ion etching (DRIE), enable precise sidewall control and profile
customization, facilitating the fabrication of complex device architectures, such as FinFETs,
nanowires, and 3D memory structures.
Damage-Free Etching and Low-K Dielectric Preservation: With the increasing use of low-k
dielectric materials in semiconductor devices to minimize signal delay and crosstalk, there is a
growing emphasis on damage-free etching techniques that preserve the integrity of these
sensitive materials. Plasma etching processes, such as downstream plasma etching and
cryogenic etching, offer reduced ion energy and temperature, minimizing damage to low-k
dielectrics and preserving their electrical properties.
Etch-Depth Uniformity and Across-Wafer Variability: Achieving uniform etch depths and
minimizing across-wafer variability are critical for ensuring consistent device performance and
yield in semiconductor manufacturing. Advanced plasma etching systems incorporate real-time
process monitoring and control capabilities, such as optical emission spectroscopy (OES) and
endpoint detection, to achieve precise etch-depth uniformity and minimize variations across
the wafer, enhancing process repeatability and yield.
High-Aspect-Ratio Etching and Through-Silicon Via (TSV) Fabrication: The increasing demand for
high-aspect-ratio structures, such as through-silicon vias (TSVs) and microelectromechanical
systems (MEMS), requires plasma etching techniques capable of etching deep, narrow features
with high aspect ratios. Deep silicon etching (DSE) and Bosch process-based etching enable the
fabrication of TSVs and MEMS devices with precise control over sidewall profiles, aspect ratios,
and etch depths, facilitating the integration of 3D device architectures and heterogeneous
integration.
