A photoresist exposure process is disclosed which produces features which are substantially smaller than the aperture dimension of the mask used to make the feature. The smaller feature size results from a double exposure of the photoresist, combined with a double baking process to create the features in the photoresist. The double baking process thins the layer of photoresist, prior to the second exposure, thereby improving the resolution of the mark created by the second exposure on the photoresist. The process also uses a binary bias mask through which the first exposure is made, which overlaps with the area of the second exposure, to allow a process tolerance for the realignment of the mask over the wafer for the second exposure.

A guitar strap including lasso-like connectors at either end, allowing the strap to be fastened to the guitar by placing the sliding loops over the guitar's strap-buttons and pulling tight. A pull-tab near the sliding eye on the sliding loops is used to pull the loop back open and disconnect the strap end from the guitar. An elastic ring incorporated into the pull-tab stretches over the button head and fastens onto the button to prevent the sliding eye from loosening open when there is no tension on the strap. Each connector is positioned in a sling formed by folding a length of the strap band. The strap band has soft loop material on its surfaces and a section of hook tape fixed to either end to facilitate adjustment of the overall strap length. The tape adheres to nearly any location along the top surface of the band, allowing the length of the strap to be adjusted quickly in large or small increments. The loop material along both sides of the strap band allow users to affix hook-tape to a variety of objects such as wireless transmitters, audio recorders, and decorations and attach them to the strap as desired.
