Toshiba to relocate Thai operations to new semiconductor facility

24 April 2012

Toshiba's Thai operations ground to a halt last year as floods devastated the countryToshiba has announced it will build a new production facility to relocate its semiconductor operations and redress the problems caused by the 2011 floods and to meet future growth demands. The plant, which will be operated by subsidiary Toshiba Semiconductor Thailand Ltd (TST), will be 135,000 square metres and be due for completion in the spring of 2013, production will begin in the subsequent months.

New Product: Applied iSYS fully-integrated abatement and vacuum pumping solution reduces energy use

02 December 2009
Product Briefing Outline: Applied Materials has unveiled its ‘Applied iSYS’ platform, the industry’s first fully-integrated abatement and vacuum pumping solution for controlling emissions in the semiconductor fab. Networked with an Applied process tool, the iSYS system can deliver typical annual savings in power, water and gas consumption equivalent to 200MWh of energy or 220,000 pounds of CO2 emissions, compared to currently available configurations. In addition to having environmental benefits, the iSYS system lowers the utility cost for abatement and vacuum pumping on a process tool by more than 20%. Read more >>

Edition 38: Chiller plant optimization

21 January 2009

FT38By Terrence Morris & Steve Blaine PE, CH2M HILL, Oregon, USA

Outside of the process tools themselves, the chilled water plant is typically the single largest consumer of electrical energy in a semiconductor facility. This load includes not just chillers but also cooling tower fans, primary pumps, secondary pumps and condenser pumps. In order to meet the cooling requirements for any particular heat load, many different combinations of this equipment can be run. However, electricity consumption varies considerably depending on the combination of equipment used and the operating levels of the individual components. Selecting the optimal mix of equipment and operating levels presents a substantial challenge for an automatic control system and plant operators. Typically, no method is available to predict the effect of interactions and variations in load demand and outside air. This makes it challenging, if not impossible, to find an equipment mix that achieves optimal energy use. In response to this challenge, we set out to create a model/tool that would allow operators to automatically determine the optimal equipment mix to satisfy cooling requirements and minimize energy use. This paper describes how this model was created and how it works.
