41.   Silicon wafers are the material for semiconductor chips.

42.   Sputtering targets, made of aluminum, titanium and tungsten, are used by semiconductor makers to lay down fine metal films on silicon wafers.

43.   Taiwan Semiconductor Manufacturing Co., which turns out silicon wafers by the billions for Silicon Valley designers, is winning more and more orders, too.

44.   Strong sales of silicon wafers for semiconductor production were not enough to compensate for weakness in other areas, Veba said.

45.   That means scores or even hundreds of them could be made from a single silicon wafer.

46.   That raises prices Korean companies must pay for imported supplies such as silicon wafers and chip-making equipment.

47.   The change in processing technology involves increasing the size of the round silicon wafers from which chips are culled.

48.   The change involves increasing the size of the round silicon wafers from which chips are culled.

49.   The chips are tiny silicon wafers, less than an inch square, to which tens of thousands of DNA genetic probes are attached.

50.   The beads were placed in micromachined wells on a silicon wafer.
