A semiconductor manufacturing line includes an inert environment selected from the group consisting essentially of an inert airtight wafer holder, an inert wafer transport channel, an inert production tool, an inert clean room, and combinations thereof.

Preventing contamination in integrated circuit manufacturing lines

A memory device includes a memory array, an I/O circuit for accessing the memory array, and a tracking circuit. The tracking circuit includes a dummy bit line, a first tracking cell including a first NMOS transistor, the first tracking cell being coupled to receive a control signal and also coupled to the dummy bit line through the first NMOS transistor, and a second tracking cell including a second NMOS transistor, the second tracking cell being coupled to receive the control signal and also coupled to the dummy bit line through the second NMOS transistor, a gate of the second NMOS transistor being coupled to the dummy bit line. The memory device also includes a control circuit coupled to the dummy bit line for generating a clock signal for the I/O circuit.
