20090321248 | LOW DAMAGE SPUTTERING SYSTEM AND METHOD - A sputtering system includes a disk-shaped target concentric with an annular anode in a reaction chamber. A thermally-sensitive sample is arranged in the reaction chamber so as to receive material sputtered from the target. The thermally-sensitive sample can be a soft tissue biological specimen. A magnet is arranged proximal to the sample within the reaction chamber. The magnet can be a U-shaped magnet or one or more bar magnets. During sputtering from the target, the magnetic field of the magnet deflects the trajectory of secondary electrons generated by the sputtering process, thereby protecting the sample from heating and damage. | 12-31-2009 |
20130056036 | INTEGRATED PROCESSING AND CRITICAL POINT DRYING SYSTEMS FOR SEMICONDUCTOR AND MEMS DEVICES - Processing and drying of a sample, such as a semiconductor or MEMS device, is achieved using a single pressure chamber. The pressure chamber holds the sample in a sealed interior volume throughout various process steps, such as, but not limited to, photoresist removal, sacrificial layer etching, flushing or rinsing, dehydration, and critical point drying. The pressure chamber is constructed of a chemically-resistant and pressure-resistant material to withstand the various chemicals and pressures that are encountered in the various process and drying steps. For example, the pressure chamber is constructed from a nickel-copper alloy. Automated release etching and critical point drying of a MEMS or semiconductor device is provided without removing the device from the sealed pressure chamber. | 03-07-2013 |
20130224724 | CRITICAL POINT DRYING SYSTEMS AND METHODS FOR IN SITU TISSUE PRESERVATION - Methods and systems for preserving tissues in situ using critical point drying are disclosed. Such methods and systems are particularly applicable to the preservation of a deceased body, such as a deceased person or animal, with or without removal of internal tissues or organs. A fixative can be perfused through the vascular system of the body while blood is removed from the body. The exterior of the body can also be immersed in a bath of fixative. The fixative in the vascular system and the bath can be replaced by subsequent washes of buffer, de-ionized water, and/or alcohol. The alcohol-infused and fixated body can be disposed in a pressure chamber and subjected to a critical point drying process using carbon dioxide. After the critical point drying process, the body is in a preserved state. | 08-29-2013 |
