Indium Gallium Zinc Oxide IGZO Sputter Targets

IGZO (Indium Gallium Zinc Oxide) sputtering targets represent a class of high-performance oxide semiconductor materials 

essential for depositing functional thin films. These targets enable precise fabrication of IGZO films with exceptional electronic 

and optical properties, making them indispensable for next-generation devices in multidisciplinary research. Below we outline 

their key application domains relevant to academic and industrial R&D laboratories.

1. Thin-Film Transistors (TFTs) for Advanced Displays

IGZO films deposited via magnetron sputtering are widely adopted as channel layers in TFTs due to their high carrier mobility, 

low off-state current, and superior uniformity over large areas. These properties drive research in:

High-Resolution Displays: Enabling ultra-HD micro-OLEDs and LCDs with enhanced pixel response speeds and reduced power 

consumption.

Flexible Electronics: Facilitating low-temperature processing compatible with heat-sensitive polymer substrates for 

bendable/foldable displays.

Stability Engineering: Investigating passivation layers (e.g., AlOₓ) and annealing processes to improve TFT stability 

against electrical/optical stress.

2. Transparent Electrodes & Optoelectronic Devices

The tunable optoelectronic properties of IGZO films support applications demanding balanced conductivity 

and transparency:

Infrared (IR) Optoelectronics: Serving as transparent electrodes in SWIR (short-wave infrared) sensors due 

to broadband transparency from visible to IR regions.

Multi-Layer Stacks: Enabling low-stress, amorphous films with smooth surfaces for complex optical coatings 

in photodetectors and imaging systems.

3. Photovoltaic & Energy Devices

IGZO’s bandgap engineering and defect tolerance make it attractive for energy conversion/storage research:

Solar Cell Electrodes: Functioning as transparent conductive layers in CIGS and perovskite solar cells.

Thin-Film Battery Components: Depositing interfacial layers to enhance charge transport in solid-state lithium batteries.

4. Emerging & Flexible Electronics

The compatibility of IGZO with non-conventional substrates unlocks novel device architectures:

Wearable Sensors: Enabling transparent, flexible circuits for biosensing and health monitoring.

Printed Electronics: Serving as a benchmark material for hybrid printed-sputtered TFT development
