TRENCHLESS TECHNOLOGY

INTRODUCTION
TT techniques include methods of pipeline & utility installations with minimum amount

of surface excavation
TT techniques are mainly divided into two main areas: TRENCHLESS CONSTRUCTION

METHODS(TCM) and TRENCHLESS RENEWAL METHODS(TRM)
TCM includes all methods for new utility & pipeline installations
TRM includes all methods of renewing, rehabilitating, or renovating an existing old

or host pipeline or utility system
Trenchless construction and ren ....etc

body of salt water; covering approximately one-fifth of the total ocean area of the world. It is the smallest, youngest, and physically most complex of the world's three major oceans. Stretching for more than 10,000 km, between the southern tips of Africa and Australia and, without its marginal seas, it has an area of about 73,440,000 sq km. The Indian Ocean's average depth is 3,890 m and, its deepest point, in the Sunda Deep of the Java Trench off the southern coast of Java, is 7,450 m.
The Indian Ocean is bounded by Ira ....etc

ABSTRACT

Low-k dielectrics are the very latest path breaking development in the field of Integrated Electronics. It is well on its way replacing the Al / SiO2 interconnects with the help of copper in CMOS fabrication of IC Chips. The CMOS technology has an in-built coupling capacitance which increases the time delay, thereby reducing associated processing speeds. This was compensated by reducing the thickness of the Al / SiO2 interconnects. There is a limit to the reduction in t ....etc

Abstract
This paper describes the realization andcharacterisation of DTI (deep trench isolation)on thick (60μm) SOI (Silicon On Insulator)wafers for domestic and automotiveapplications . In this aim, DTI processoptimisation and adaptation permits to identifythe key parameters in breakdown voltagecapability. The role of different parts ofelaborated DTI was found to demonstrate thepossibility of good results in breakdownvoltage – up to 600V.

Chemical Mechanical Planarization (CMP) is an important process in semiconductor chip fabrication. In the CMP process, excess material is removed and the surface is planarized by the action of chemical and mechanical forces. Shallow Trench Isolation (STI) has become a key technology for device isolation in recent times. In this method, a shallow trench is made on the silicon wafer between active devices, silicon dioxide is deposited over the trench as well as the active area and the excess silicon dioxide is removed by CMP. The oxide remaining ....etc

Free Space Optics (FSO) communications, also called Optical Wireless (OW)
Bo Rong, Yi Qian, Member, IEEE, and Kejie Lu, Member, IEEE
Overview

Imagine a technology that offers unsurpassed reliability and

high-speed connectivity. A technology that can be installed globally is

easy to deploy, license-free and offers a fast, high ROI. That

technology is free-space optics (FSO).

Free Space Optics (FSO) communications, also called Optical

Wireless (OW) or Infrared Laser, refers to the transmission of

modulated visible or infrar ....etc
