Each shallow member has a layer of closed cell foam material positioned along the inside of the upper wall of the shallow member.

Abstract: Quantitative dopant profile measurements are performed on a nanometer scale by using a scanning capacitance microsope. A nanometer scale tip of the microscope is positioned at a semiconductor surface, and local capacitance change is measured as a function of sample bias. The method incorporates a feedback system and procedure in which the magnitude of the AC bias voltage applied to the sample is adjusted to maintain a constant capacitance change as the tip is scanned across the sample surface. A one dimensional model is used to extract dopant density profiles from the measurements made by the scanning capacitance microscope.

Abstract: A method is disclosed for permanently repairing roofs using a colloidal clay such as sodium montmorillonite (commonly called bentonite). A layer of particles of the colloidal clay is spread on the surface of the roof that is to be repaired so that the layer of colloidal clay covers any cracks or openings in the roofing material that are causing leaks. A membrane made of water impermeable material is then applied over the layer of colloidal clay particles so as to confine the particles underneath the membrane. During a rainstorm, water wets the colloidal clay, and the clay swells rapidly to form a water tight blockage between the roof and the membrane. Rain water cannot infiltrate beneath the membrane and thus cannot leak through holes or openings in the roof material that have been covered by the layer of colloidal clay and the membrane. The colloidal clay material is held permanently in place beneath the membrane, and thus the repair is a permanent repair rather than a temporary repair.
