An embodiment of the present invention provides a method for manufacturing a semiconductor device. The straw has a tube wall with an expanded portion proximate an outlet. Alternatively, the transparent planar glass can be eliminated and a spacer used to adjust the mounting of the direct view camera to the support so as to restore a sight line for the direct view camera. Each separate groove extends in the separate active region and does not extend over the isolating region. So produced aldehydes are converted in an ex vivo process to corresponding alcohols. A preferred laser treatment includes topical application of an energy activatable material to the skin followed by laser irradiation.
