Title: Fabrication of dielectric in trenches formed in a semiconductor substrate for a nonvolatile memory
Inventor: WU KUO-CHUN
IPC: H01L21/8247
Filed: 2002-10-18
Granted: 2003-11-11
Abstract: To form substrate isolation for a nonvolatile memory, floating gate polysilicon (410) is formed over a semiconductor substrate (110), then silicon nitride (130) is deposited, and then the nitride, the floating gate polysilicon and the substrate are etched to form isolation trenches (140). Dielectric (150) is formed in the trenches and over the silicon nitride. The dielectric thickness is relatively small so that the top surface (150T) of the dielectric over the trenches lies at all times below the top surface of silicon nitride. The dielectric deposition and polishing times are therefore reduced. Other embodiments are also provided.

Patent TW-577964-B (TW)
Title: Tensioner
Inventor: SERKH ALEXANDER
IPC: F16H7/12
Filed: 2003-04-14
Granted: 2004-03-01
Abstract: The invention comprises a self-contained mechanical belt tensioner that produces damping which is a function of the applied hubload through the effect of frictional forces derived from the sliding action of mutually opposing wedges. A first wedge or conical piston is contained within a housing. The conical piston cooperates with a second or conical wedge. A surface of the conical wedge slides on the inner surface of the housing. The conical wedge is expandable in a direction normal to the inner surface of the housing. A spring urges the conical wedge into engagement with the conical piston. As the pulley is loaded, as with an impulse load, the piston will move into the conical wedge. This, in turn, will cause the conical wedge to expand against the inner surface of the housing. The expansion of the conical wedge in the housing will increase the frictional force between the conical wedge and the housing. This will have the effect of damping movements of the conical piston and, in turn, of the pulley. The greater the impulse, then the greater the expansion of the conical wedge. This increases the resultant frictional force resisting movement between the conical wedge and the housing. As the load moves toward a minimum, the frictional force is abated to a low level allowing ease of retraction of the piston.
