چکیده

This paper presents three coating methods of photoresist, spin, spray and electrodeposition (ED) on large topography surfaces. Characteristics of each method as well as its advantage and disadvantages are outlined. A comparison is made to point out the most suitable coating method in terms of complexity, costs and type of

Electrodeposition of Nano Hydroxyapatite Coating on Biodegradable Mg-Zn Scaffold (TECHNICAL NOTE)

Magnesium has been recently recognized as a biodegradation metal for bone substitute application. In the present work, porous magnesium-zinc scaffolds were prepared by powder metallurgical process and nano hydroxyapatite (HAP) coating on the Mg-3Zn (wt.%) scaffold was prepared by pulse electrodeposition and alkali treatment processes to improve the corrosion resistance of scaffold. The results ...

MEMS Post-Processing of MPW Dies using BSOI Carrier Wafers

Multi-project-wafer (MPW) services provide an economical route for prototyping of new electronic circuit designs. However, addition of MEMS functionality to MPW circuits by post-processing (also known as MEMS-last processing) is difficult and inefficient because MPW typically yields individual dies. One solution to this problem is to embed the MPW dies in a carrier wafer prior to MEMS processin...

Fabrication of enclosed nanochannels using silica nanoparticles

We report a simple and inexpensive approach to the fabrication of enclosed nanoscale channels composed of silica nanoparticles on planar Si surfaces using interferometric lithography to define the long-range pattern in a photoresist film followed by spin-coating self-assembly of colloidal silica nanoparticles and high-temperature calcination to remove the photoresist leaving open nanochannels. ...

Effects of temperature on mechanical properties of SU-8 photoresist material

A representative fabrication processing of SU-8 photoresist, Ultraviolet (UV) lithography is usually composed of spin coat, soft bake, UV exposure, post exposure bake (PEB), development and optional hard bake, etc. The exposed region of SU-8 is crosslinked during the PEB process and its physical properties highly depend on UV exposure and PEB condition. This work was initiated to investigate if...

Microstructures and Photovoltaic Properties of Zn(Al)O/Cu2O-Based Solar Cells Prepared by Spin-Coating and Electrodeposition

Copper oxide (Cu2O)-based heterojunction solar cells were fabricated by spin-coating and electrodeposition methods, and photovoltaic properties and microstructures were investigated. Zinc oxide (ZnO) and Cu2O were used as nand p-type semiconductors, respectively, to fabricate photovoltaic devices based on In-doped tin oxide/ZnO/Cu2O/Au heterojunction structures. Short-circuit current and fill f...
