Patent TW-283087-B (TW)
IPC: A61H23/02
Filed: 1995-02-20
Granted: 1996-08-11
Abstract: A transducer for non-invasive transcutaneous transmission of pulsed ultrahigh-frequency acoustic radiation, in body tissue and/or fluids adjacent a bone fracture is "on target" when a fraction of the propagated energy within the longitudinal-response lobe of the transducer encounters a crack or other open feature of the fracture, where a gap or space exists between closely spaced fracture walls. The ultrahigh-frequency acoustic radiation sees this "on target" feature as the entrance to a waveguide, whereby pulsed ultrahigh-frequency acoustic radiation is guided within the crack. When this acoustic radiation encounters a gap of at least a quarter wavelength (at the ultrahigh frequency), a standing wave condition establishes itself, with dissipation of the ultrahigh frequency and with demodulation to establish a therapeutically beneficial low-frequency acoustic condition, within the fracture, and acting where most needed, namely, on and between wall regions of adjacent fragments of the broken bone. Collagen, callus and cartilage development is accelerated, closing the gap in a matter of days, so that thereafter zone-flooding of shear waves from transducer radiation can be osteogenically operative upon both bone fragments of the fracture and on the collagen through which they are united at first tentatively and then increasingly more securely as treatment continues, from day to day, as with one or more single treatments of 20 minutes per day.

Title: Dry microlithography process
Inventor: MOSLEHI MEHRDAD M
IPC: H01L21/3065
Filed: 1995-11-21
Granted: 1999-09-01
Abstract: An all dry microlithography process, where a fluorinated layer 30 is deposited on a processable layer 18 of a semiconductor wafer, and regions of the fluorinated layer 30 are exposed to a masked radiation source so that exposed regions and unexposed areas 31 are formed in the fluorinated layer 30. An oxide layer is grown on the fluorinated layer forming thick region 34 of oxide on the exposed areas 31 of the fluorinated layer, and forming thinned region 32 of oxide on the exposed region of the fluorinated layer 30. The oxide layer is then etched, removing thinner regions 32 of the oxide layer but leaving at least a fraction of the thick portion 34 of the oxide layer to be used as a patterned hard mask. Then the exposed fluorinated layer not cover by the patterned oxide hard mask, is etched, to exposed areas of the processable layer 18 not covered by the oxide hard mask, for subsequently patterned processing. The subsequently patterned processing may be an etch process for pattern transfer to the processable layer, a doping process to dope the exposed regions of the processable layer, or another process such as a deposition step. The all-dry lithography can be completed in an integrated environment, such as a cluster tool, resulting in improved cycle time and increased yields. The dry photoresist layer may be deposited using PECVD at low temperature, and is compatible with all other semiconductor device fabrication process flows.
