Nanogap Dielectric Capacitor for Label Free Bio-Molecules Detection
No full textProf. Dr. Uda Hashim and his team won silver at 21st International Invention, Innovation and Technology Exhibition (ITEX) 2010, 14th - 16th May 2010 at Kuala Lumpur Convention Centre (KLCC), Kuala Lumpur, Malaysia.This research demonstrating that nanogap biosensor was fabricated by standard CMOS technologies function as extremely sensitive and selective biosensor for biomolecular detection and medical diagnostic application using label-free detection technique. The difference in dielectric properties between single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA) permits use of capacitance measurements to detect DNA hybridization which is time saving and cost effective
MOS Transistor Mask Design Using SEM Based E-Beam Lithography
No full textProf. Dr. Uda Hashim and his team won silver for MOS Transistor Mask Design Using SEM Based E-Beam Lithography at ITEX 2006, 19th - 21st May 2006 at Kuala Lumpur Convention Centre (KLCC), Kuala Lumpur.Electron beam lithography (EBL) is one of the alternative tools in transferring micro and nano circuit patterns from design editor to the substrate. EBL is state-of-the-art technology for micro and even to nano feature size in direct writing technology. SEM based EBL will be used to define the mask for device fabrication. These masks were designed in GDSII Editor in EBL System. Poly-methyl-metacrylate (PMMA) is used as a resist in the EBL
Silicon Nanowires
No full textProf. Uda Hashim and his team won gold for Silicon Nanowires. ITEX 2007, 18th - 20th May 2007 was held at Kuala Lumpur Convention Centre (KLCC), Kuala Lumpur.Silicon Nanowires is a new class of materials that have attracted attention and great research interest in the last few years because of their great potential applications in nanotechnology such as:
- nanoelectronic engineering
- nanomechanical engineering
- biomedical engineering
Fabrication of Silicon Nanowires is one of the great challenges today. Conventional lithography methods are not capable to produce Nanowires and even with advance nanolithography sizes below 100nm may not easily be achieved. The goal of this project is to form and produce very small Silicon Nanowires using a Top Down Nanofabrication Method which involved Scanning Electron Microscope (SEM) based Electron Beam Lithography (EBL) method
MOS Transistor (Fabricated Using In-House Low Cost Facilities)
No full textProf. Dr. Uda Hashim and his team won silver for MOS Transistor (Fabricated Using In-House Low Cost Facility) at ITEX 2006, 19th - 21st May 2006 at Kuala Lumpur Convention Centre (KLCC), Kuala Lumpur, Malaysia.MOS Transistor is divided into two types: NMOS and PMOS. Majority carrier od NMOS is electrons whereby PMOS is holes. The MOS transistor consists of three regions namely source, drain and gate. Fabrication of MOS transistor is done on 100mm silicon wafer. The active region of the transistor, which are source and drain are formed by either solid or liquid dopant. These transistors were fabricated using in-house low cost facility which is designed and developed by KUKUM internal expertise. The fabrication work is done in the cleanroom Class ISO 5 and ISO 6

Silicon Nanowires Based DNA Biosensor
No full textProf. Dr. Uda Hashim and his team won bronze at Malaysia Technology Expo 2010 (MTE 2010), 4th - 6th February 2010 at Putra World Trade Centre (PWTC), Kuala Lumpur. MTE 2010 organized by MARS and PROTEMP Exhibitions Sdn. Bhd.This research describes the fabrication of silicon nanowire for DNA hybridization detection in biosensor application. The SiNWs are fabricated by electron beam lithography and followed by deposition of contact metals. Aurum is a suitable metal to make Ohmic contact with SiNWs and its exhibit electrical transport measurements of the devices. The presence of the hybridization DNA will induce electronic charge and changed the electronic properties of the devices from which detectable electronic signals are generated
