Title: Ordered structures in homogeneous magnetic fluid thin films and method of preparation
Inventor: HORNG HERNG-ER
IPC: G02F1/09
Filed: 1998-03-20
Granted: 2002-01-01
Abstract: Methods for preparing homogeneous magnetic fluid compositions capable of forming ordered one dimensional structures or two dimensional lattices in response to externally applied magnetic fields are disclosed. The compositions are prepared using improved co-precipitation methods in which the steps of the procedure have been tuned to reduce sample heterogeneity. Fe3O4 particles are coated with a surfactant and dispersed in a continuous carrier phase to form these homogeneous magnetic fluid compositions. The ability of these compositions to generate ordered structures can be tested by holding a magnet near a thin film of the compositions and observing the formation of colors in the region near the magnet. Methods for controlling the characteristic spacing of the ordered structures formed by the composition also are disclosed. Relevant parameters include the thickness of the film, the strength and orientation of the externally applied magnetic field, the rate of change of field strength, the volume fraction of the magnetic particles dispersed in the continuous phase, and the temperature of the homogeneous magnetic fluid. The homogeneous magnetic fluid composition is useful for the manufacture of liquid crystal devices. The devices take advantage of the serendipitous fact that the spacings in the material are on the order of the wavelength of visible light. A variety of magnetic-optical devices can be constructed that use the ordered structures to diffract, reflect, and polarize light in a controlled and predictable manner. These devices include color displays, monochromatic light switches, and tunable wavelength filters.

Title: Device with asymmetrical channel dopant profile
Inventor: GALL MARTIN
IPC: H01L21/336
Filed: 1998-03-25
Granted: 2002-07-21
Abstract: A method for fabricating a bit line junction in a DRAM array device which improves the doping profile in the channel region. The method includes contradoping via ion implantation through the bit line contact opening made in the device during processing. This particular doping method increases the concentration of dopants in the channel region on the bit line side of the array, without a corresponding increase of dopants on the buried strap side. Such a doping profile results in an improvement in the off current behavior of the device. Depending on the aspect ratio of the contact opening, tilt angles for the ion implantation are possible and can be adjusted for maximum off current efficiency.

Title: Plasma process for selectively etching oxide using fluoropropane or fluoropropylene
Inventor: WANG RUIPING
IPC: H01L21/768
Filed: 1998-08-27
Granted: 2001-06-23
Abstract: A plasma etch process, particularly applicable to an self-aligned contact etch in a high-density plasma for selectively etching oxide over nitride, although selectivity to silicon is also achieved. In the process, a fluoropropane or a fluoropropylene is a principal etching gas in the presence of a substantial amount of an inactive gas such as argon. Good nitride selectivity has been achieved with hexafluoropropylene (C3F6), octafluoropropane (C3F8), heptafluoropropane (C3HF7), hexafluoropropane (C3H2F6). The process may use one or more of the these gases in proportions to optimize selectivity and a wide process window. Difluoromethane (CH2F2) or other fluorocarbons may be combined with the above gases, particularly with C3F6 for optimum selectivity over other materials without the occurrence of etch stop in narrow contact holes and with a wide process window.
