A feature in a layer is provided. One method embodiment includes receiving an indication of a die and a plane associated with at least one address cycle. Thus expansion of the temperature range is suppressed. The pull-up resistor may include a first gate. Next, a first etchant is utilized to perform a first etching process for etching a portion of the wetting and barrier layers by utilizing the solder as a mask, in which the first etchant is selected from the group consisting of: sulfuric acid, phosphoric acid, ferric chloride, ammonium persulfate, and potassium monopersulfate. Allowing the solitons to change in amplitude, width and shape while traversing the dispersion compensating optical regenerator provides for beneficial system performance including improved signal to noise ratio at the receiver, reduced impact of signal interactions, and longer regenerator spacing.
