EUV Photoresist

EUV Photoresist 소개.png

Extreme Ultra Violet (EUV) lithography is the  promising technique of next-generation semiconductors for continuation of Moore's law. However, existing chemically amplified resists have some limits because of poor pattern transfer and pattern collapse. Therefore, the development on photorsists with high photon adsorption and moderate etch selectivity is needed for EUV lithography.

Phtoelectrochemical(PEC) Cells

Photoelectrochemical (PEC) cells are useful devices designed for the chemical process of generating hydrogen via electrolysis of water, namely water splitting, under irradiation of a broad spectrum of sunlight. In general, PEC devices are composed of photoelectrodes, where oxidation/reduction of water occurs with response to sunlight, and appropriate aqueous electrolytes containing a redox couple. 

Supercapacitors

Supercapacitors (SC), comprise a family of electrochemical capacitors. Supercapacitors, sometimes called ultracapacitors or electric double- layer capacitor (EDLC), don't have a conventional solid dielectric. 

Synthesis of 2D Material

Graphene is a material composed of pure carbon atoms, arranged in a regular hexagonal pattern. Graphene can be described as a one-atom thick layer of the mineral graphite (many layers of graphene stacked together effectively form crystalline flake graphite). It has drawn a lot of attention due to its great properties such as high optical transmittance, excellent electrical conductivity, high flexibility, and large theoretical surface area, and great mechanical stability.

Desalination

Capacitive Deionization (CDI) is a promising desalination technique which has attractive advantages, such as low technology cost, low energy, and environment friendly characteristics. For above reasons, the CDI technology has received considerable attention over last ten years. As an electrochemical process, CDI is based on electrical double layer(EDL) principle which is same to EDL capacitpr. 

1D, 2D, 3D nano-periodic structure

Holographic Interference Lithography (HIL) is a fast and efficient technique that allows one to create 1D, 2D and 3D (Three-Dimensional) nano-periodic structures with large-area and defect-free coverage. Additionally, this technique offers increased control over cell geometry and volume fraction. Because of many advantages that IL offers for 3D fabrication, it became subject of very active investigations in recent years. 

Surface-enhanced Raman Spectroscopy(SERS)

Raman scattering is an important phenomenon to understand the molecular structure using inelastic scattering data obtained by excitation of laser onto the sample. In 1977, Van Duyne found the strong enhancement in the metal electrode which he named as surface enhanced Raman Scattering (SERS).
