摘要:
A method of making MOS integrated circuits employs high-pressure oxidation of the surface of a silicon slice to create thermal field oxide for device isolation. The implant used prior to this oxidation to provide the channel-stop regions beneath the field oxide may be at a lower dosage, and yet the field-transistor threshold voltage is maintained at a high level. Thus, encroachment of the channel stop impurity into the transistor channel is minimized, and higher density devices are permitted.
