Abstract:
A multi-step cleaning procedure cleans phase shift photomasks and other photomasks and Mo-containing surfaces. In one embodiment, vacuum ultraviolet (VUV) light produced by an Xe2 excimer laser converts oxygen to ozone that is used in a first cleaning operation. The VUV/ozone clean may be followed by a wet SC1 chemical clean and the two-step cleaning procedure reduces phase-shift loss and increases transmission. In another embodiment, the first step may use other means to form a molybdenum oxide on the Mo-containing surface. In another embodiment, the multi-step cleaning operation provides a wet chemical clean such as SC1 or SPM or both, followed by a further chemical or physical treatment such as ozone, baking or electrically ionized water.
Abstract:
A semiconductor structure for dissipating heat away from a resistor having neighboring devices and interconnects. The semiconductor structure includes a semiconductor substrate, a resistor disposed above the semiconductor substrate, and a thermal protection structure disposed above the resistor. The thermal protection structure has a plurality of heat dissipating elements, the heat dissipating elements having one end disposed in thermal conductive contact with the thermal protection structure and the other end in thermal conductive contact with the semiconductor substrate. The thermal protection structure receives the heat generated from the resistor and the heat dissipating elements dissipates the heat to the semiconductor substrate.
Abstract:
A method for forming a semiconductor structure is provided to prevent energy that is used to blow at least one fuse formed on a metal layer above a semiconductor substrate from causing damage on the structure. The semiconductor structure includes a device, guard ring, protection ring, and at least one protection layer. The device is constructed on the semiconductor substrate underneath the fuse. A seal ring, which surrounds the fuse, is constructed on at least one metal layer between the device and the fuse for confining the energy therein. The protection layer is formed within the seal ring, on at least one metal layer between the device and the fuse for shielding the device from being directly exposed to the energy.
