Gate oxide can go really very thin down to atomic width and still work fine...but it all depends on the technology used. The upper limit is that gate oxide can't go below the width of one atom of the gate oxide material . However this is theoretical, in practical...its at least 5 times of above. If its very thin, yes it will result in failture of device with gate material shorted to channel.
