Silicon nanowire transistor (SiNWT) is a new promising alternative architecture to the conventional planar technology for electronic device fabrication. In this invention, SiNWT is fabricated via formation of a nanoscale silicon oxide pattern on silicon-on-insulator (SOI) wafer using an atomic force microscopy (AFM) nanolithography. The AFM nanolithography technique is advantageous due to the imaging capability of AFM and the ability to write various patterns by controlling the probe movement over the sample surface. In AFM nanolithography, the force between the tip and sample surface is held constant while a fixed voltage bias is applied to generate the field-emitted current. To fabricate SiNWT pattern by AFM nanolithography, applied voltage between tip and sample surface, tip writing speed and environment humidity are controlled. Our SiNWT is consisted of a silicon nanowire as a channel with a set of source (S) and drain (D) pads. A lateral gate (G) pad is connected by another nanowire made to be as close as possible to the channel in the transistor structure. The fabrication process steps are including a SOI wafer preparation, patterning of a silicon nanowire transistor structure on SOI wafer by AFM nanolithography, and the etching processes of silicon layer and oxide patterns.

dah bersara ke?

dah bersara ke blog ni?
not really yet! but why is static for so long time? busy.... busy and busy is a good reason. actually malas aje! bosan pun juga.

But

Currently, I'm setting up a new blog at http://sdhutagalung.com/. It still under development. Please visit it later. sabar ya......

KUALA LUMPUR 10 April — Timbalan Perdana Menteri Tan Sri Muhyiddin Yassin hari ini mengetuai barisan menteri dan timbalan menteri yang dilantik semalam mengangkat sumpah jawatan dan taat setia serta sumpah simpan rahsia di hadapan Yang di-Pertuan Agong Tuanku Mizan Zainal Abidin di Istana Negara.

Upacara penuh adat istiadat itu disaksikan oleh Pemaisuri Agong Tuanku Nur Zahirah dan Perdana Menteri Datuk Seri Najib Tun Razak serta bekas perdana menteri Tun Abdullah Ahmad Badawi dan Tun Dr Mahathir Mohamad.

Upacara itu yang diadakan di Balairong Seri Istana Negara bermula tepat 9.30 pagi dengan penerimaan surat cara pelantikan oleh Muhyiddin selaku Timbalan Perdana Menteri.

Beliau melafazkan ikrar sumpah jawatan dan taat setia dan kemudian menandatangani dokumen rasmi pelantikan disaksikan oleh Presiden Mahkamah Rayuan Tan Sri Alauddin Mohd Sheriff dan Ketua Setiausaha Negara Tan Sri Mohd Sidek Hassan. - Bernama

Sanggar Sanjung Award 2008

In this picture from left to right: Prof. Zainal, Prof. Farhan, Tan Sri Dato' Dzulkifli Abdul Razak (VC USM), me, Dr. Azmin and Dr. Cheong


I receipt a sanggar sanjung award for Journal Publication category presented by D.Y.M.M Tuanku Tengku Fauziah Binti Al-Marhum Tengku Adul Rashid (Raja Perempuan Perlis) during The Sanggar Sanjung Award Night 2008 ceremony held at Equatorial Hotel, Penang last night (24 March 2009, 8 - 11 PM). This is my third sanggar sanjung award since 2005. I miss only 2006 award.

The Sanggar Sanggung Award is a recognition confererred by Universiti Sains Malaysia (USM) to its academic staff who have enhanced USM's reputation by attaining excellence in research and academic activities annually. The formal evening, in which the awards are presented, is one of the most prominent events held by the university (USM).

Commencing in 2001, staff who have succeeded in producing an innovative product, published an internationally acclaimed and peer reviewed publication or who are recipients of awards at international or national level are feted at a glitzy gala event tagged the Sanggar Sanjung Night.
