Title: Method and apparatus for trimming the optical path length of optical fiber components
Inventor: CHEN GANG
IPC: G02B6/34
Filed: 2000-07-09
Granted: 2001-08-01
Abstract: The method and apparatus of the present invention achieves the trimming and, therefore, tuning of fiber optic devices by, in one embodiment, precisely heating a small area of a fiber to allow its elongation when mounted under tension in its package. By pulsing a source of heat in precise amounts, the elongation can be precisely controlled within 1 picometer precision over a tuning range of about 200 picometers. In another embodiment with fibers having core dopants which can be diffused, the optical length of an optical fiber can be trimmed with nanometer precision. By employing a controlled source of localized energy applied to the optical fiber, real time trimming can be achieved in both systems by injecting a broad band source of energy at the input of the device and coupling a spectral analyzer at its output to monitor the frequency characteristic of the optical device during trimming. In a preferred embodiment, the energy source comprised a CO2 laser having a relatively narrow beam corresponding to the diameter of the optical fiber. Energy from the laser is directed to a small area of the optical fiber in pulses which provide precise control of the trimming process.

A low k dielectric film is then deposited on top of the phosphorus or boron-containing metal alloy film. The structure is then heated in a second annealing process in a reducing atmosphere to a temperature of at least 300 DEG C for at least 1 hour. It is also possible to anneal in a single process after sequential depositions of metal and dielectric layers. An electrical conductor in a semiconductor structure is further disclosed which includes a metal conductor situated in an insulator layer, a film of a phosphorus or boron-containing metal alloy on top of the metal conductor, and a film of a dielectric material on top of the metal alloy film.

Title: Manufacturing of semiconductor wafer
Inventor: HARADA SEIJI
IPC: B24B37/24
Filed: 2001-04-24
Granted: 2002-10-21
Abstract: To provide a semiconductor wafer having a surface and a rear surface having different glossiness at low cost and its glossiness can be selected arbitrarily. A silicone wafer W is inserted into each holding hole 11a of a carrier plate 11 by a double-sided polishing device without fixed star gears. The rear surface of each wafer faces upward. A foaming urethane foam pad 14 and a non-woven fabric pad 15 are pressed against the rear surface and the surface of the wafer, respectively. Slurry is supplied from a central part on an upper surface plate 12 side so that a carrier holder 20 and the carrier plate 11 perform circular movement without revolution in a horizontal plane. As a result, the surface and the rear surface of each silicone wafer W are uniformly polished on the whole surfaces. At this time the urethane pad 14 provides a smaller sinking amount of the wafer than that of the non-woven fabric pad 15, thereby providing the polished wafer having pear skin-like rear surface and mirror-like surface. Furthermore, use polishing pad having different sink amount on the front and rear surface and let the rotation speed of the top and bottom table be different. Accordingly, there occurs a difference between the polishing amount of the front surface of the wafer and the polishing amount of the rear surface of the wafer. Thus, the obtained wafer W has different glossinesses on the front and rear surfaces.

Granted: 2003-04-01
Abstract: The present invention provides a method, apparatus, and system for controlling memory accesses to multiple isolated memory areas in an isolated execution environment. A page manager is used to distribute a plurality of pages to a plurality of different areas of a memory, respectively. The memory is divided into non-isolated areas and isolated areas. The page manager is located in an isolated area of memory. Further, a memory ownership page table describes each page of memory and is also located in an isolated area of memory. The page manager assigns an isolated attribute to a page if the page is distributed to an isolated area of memory. On the other hand, the page manager assigns a non-isolated attribute to a page if the page is distributed to a non-isolated area of memory. The memory ownership page table records the attribute for each page. In one embodiment, a processor having a normal execution mode and an isolated execution mode generates an access transaction. The access transaction is configured using a configuration storage that contains configuration settings related to a page and access information. An access checking circuit coupled to the configuration storage checks the access transaction using at least one of the configuration settings and the access information and generates an access grant signal if the access transaction is valid.
