Abstract

The present invention relates to a method for manufacturing a semiconductor wafer having a SOI wafer-like structure which is prepared on a silicon substrate by electrochemical etching, and an active-driven liquid crystal display employing the semiconductor wafer as a pixel switching wafer. In accordance with the method for manufacturing the SOI-type semiconductor wafer, a wafer having a good electrical insulation property, low leakage current and small parasitic capacity, like a SOI wafer, can be prepared, by employing a silicon substrate which is cheaper than the SOI substrate.
