1.   And in combination with the move to smaller circuitry, the larger wafers will enable Intel to quadruple the output of existing factories, the company says.

2.   But testing a new generation of manufacturing equipment able to process the larger wafers is expensive.

3.   Larger wafers promise to yield a greater chip harvest, boosting profits.

4.   The larger wafers are needed to boost production of more powerful memory chips that are due out early next century.

5.   The larger wafers reduce costs and improve productivity, but require expensive new chip-making equipment.

6.   Those larger wafers will require new manufacturing equipment.
