A thin-film semiconductor device having a CMOS inverter comprising a pair of n-type and p-type thin-film transistors, wherein the gate electrode of at least one of the paired thin-film transistors comprises a plurality of gate electrode sections spaced apart along the channel length. The channel region of the n-type thin-film transistor is doped with p-type impurities. This structure serves to reduce the leakage current and maintain high OFF resistance for a high source-drain voltage. Further, since a good symmetry of characteristics is maintained between the n-type and p-type thin-film transistors that constitute the CMOS inverter, no appreciable bias is caused in the output voltage of the CMOS inverter.

A cleaning apparatus in accordance with the present invention includes a first inflow section, provided on a first side surface of a cleaning tank having a substantially rectangular parallelopiped shape, having two inflow openings, a second inflow section, provided on a second side surface facing the first side surface, having inflow openings, and outflow openings for releasing a cleaning liquid flown in from the first and second inflow sections. The cleaning liquid flowing in from the inflow openings forms complex and strong flows in the cleaning tank, thus removing contaminants on a cleaning target evenly and efficiently without nonuniformity and preventing stagnation of the cleaning liquid in the cleaning tank. The cleaning liquid released in filtered by a circulatory section and is allowed to flow into the cleaning tank again through a pipe. As a result, it is possible to clean evenly and efficiently a large cleaning target such as a glass substrate used for liquid crystal display devices and other devices.
