TAIPEI — Taiwan Semiconductor Manufacturing Co. (TSMC,台積電), the world’s largest contract chip-maker, uses 5.66 liters of water for every square centimeters of wafer produced, saving several times more water than rivals in the United States, Japan and South Korea, company data showed Thursday.

For the same size of wafer produced, TSMC saves 3 times more water than manufacturers in the U.S., twice as much as those in Japan and 1.5 times more water than companies in South Korea, which are home to the world’s major chip-makers, TSMC data showed.

It noted one of the ways it is able to conserve water is by reusing water.

“TSMC uses each drop of water 3.5 times, and the company this year aims to increase the recycling rate to 4 times,” said Tony Chen, a section official of Fab 15, one of the compmay’s three facilities that produce 12-inch wafers, in Central Taiwan Science Park in Taichung.     [FULL  STORY]
