An independent leadframe transport system for use with an integrated-circuit processing unit. A logical control channel to be transmitted on a physical channel of a macro cell in the macro cell network is selected as the channel to be tested. The casing is provided with a main casing having first through holes and a cover having second through holes. The first position allows a wearer to look through the first lens and the second lens, and the second position is substantially away from the first position in a direction toward the temple member. An embodiment utilizes apparatus comprising a waveform controller and a waveform generator that are controlled by the waveform controller. Anti-etch films are formed in the top corners of the device isolation film using a material that has a different etch selectivity ratio from nitride or oxide and is not etched in an oxide gate pre-cleaning process.
