Normally you just need to set the layer as 50% transparent and export. But you have to export to an adequate format that supports partial transparency, JPG has no transparency, and GIF has binary transparency only (same AFAIK for the .ICO format, since you call this thing an "icon"). Recommended format would be PNG.
This said, the image is very simple to recreate from scratch, for instance with two overlapping and perpendicular rounded rectangles: make a vertical rectangle with rounded corners, duplicate it, rotate each copy 45° in opposite directions.
