摘要
CMOS/SOI devices as well as 51-stage ring oscillators with channel design length of 1 μm are fabricated using 4 inch SIMOX wafers. SOI MOSFETs show high saturated current while still remaining the cut-off current very low. Unloaded 51-stage ring oscillators reported here have very good speed performance. Under 5 V supply voltage, the delay per stage reaches 92 ps. These results are attributed to excellent short-channel characteristics as well as low parasitic performance in CMOS/SOI, which verifies that there is significant room for continued performance improvement in scaled CMOS/SOI.
