Title: A method for formulating a green pigment composition containing no halogen
Inventor: HATAKEYAMA YASUHHIKO
IPC: H05K1/02
Filed: 2000-06-21
Granted: 2003-02-11
Abstract: A process for preparing a green pigment composition which comprises subjecting a mixture of a halogen-free blue pigment material and a halogen-free yellow pigment material to size reduction; the size reduction desirably comprises (1) kneading the pigment mixture in the presence of a grinding medium or (2) dissolving the said blue pigment material and yellow pigment material in a strong acid to obtain a solution and injecting the solution into water to recover the pigment materials as a precipitate. This process provides a high-quality pigment composition which has a green hue completely free from the problem of shading into white and contains sufficient light resistance and heat resistance. The pigment composition obtained is highly suitable for use in the coloring of plastics required to be processed at a high temperature, and is highly safe and hygienic and does not lead to an environmental problem.

Title: Method and apparatus for regenerating catalytic filters
Inventor: STRAUB PETER
IPC: B01J38/02
Filed: 2000-06-21
Granted: 2003-05-11
Abstract: The method is used to regenerate a catalytic filter (28, 30) which is used in particular in refuse incineration plants for cleaning flue gases and is suitable for mechanically separating out solids and for cleaning or converting gaseous contaminants. In this method, the catalytic filter (28, 30) is heated to a temperature which is above its operating temperature. At the same time, a carrier gas is fed to the catalytic filter (28, 30), so that the catalytic filter (28, 30) is regenerated by simultaneous thermal and mechanical treatment. The method according to the invention, which is easy and inexpensive to carry out, therefore enables the mechanical and catalytic filter action of the catalytic filter to be restored rapidly by simultaneous mechanical and thermal treatment. The apparatus allows sequential regeneration of the catalytic filters (28, 30), so that the flue gas cleaning installation (10) can be run without interruption even when the catalytic filters (28, 30) are being regenerated.

The bit line structure contains the bit line which is electrically connected with the bit line contact window, the cap layer which is on top of the bit line, and the spacer of the bit line and the cap layer sidewall. After that, the second insulating layer, the etching stop layer and the third insulating layer are sequentially formed on the substrate. An opening is formed in these three layers in order to expose one part of the bit line structure and the first section of node contact window. The first conductor layer which is conformal with the opening is formed in the opening, and is used as the second section of node contact window as well as the lower electrode of the crown-shaped capacitor. Finally, the conformal dielectric layer and the second conductor layer are sequentially formed on the substrate in which the second conductor layer is used as the upper electrode of the crown-shaped capacitor.

Title: Substrate treatment method
Inventor: SUZUKI FUJIO
IPC: C23C16/46
Filed: 2001-02-16
Granted: 2003-10-21
Abstract: This invention relates to a substrate treatment method. A plurality of wafers W are mounted on a wafer boat 11 in a reaction tube 1 having a double-tube structure as shelves, and zones 6a, 6b and 6c in the reaction tube 1 are heated to a first process temperature, e.g., 770 DEG C, by heating parts 4a, 4b and 4c of a heater 4, respectively. Then, while the temperature in each of the zones 6a, 6b and 6c is lowered to a second process temperature, e.g., 750 DEG C, which is lower than the first process temperature, a deposition gas is fed to deposit a thin film. If a step of raising the temperature in each of the zones 6a, 6b and 6c and a step of feeding the deposition gas while lowering the temperature of each of the zones 6a, 6b and 6c are repeatedly carried out, a deposition process is carried out while the temperature of the peripheral edge portion of each of the wafers W is lower than the temperature of the central portion of the wafer W. Thus the uniformity of the thickness of the film deposited on each of the wafers is improved. The temperature dropping rate in each of the zones 6a, 6b and 6c is separately set for each of the zones to achieve the optimum deposition process in each of the zones.

Title: Method of a surface treatment in impromoving adhesion of an organic polymeric low-k dielectric layer
Inventor: HSIEH TSUNG-TANG
IPC: H01L21/205
Filed: 2001-08-10
Granted: 2002-11-21
Abstract: A method of coating an organic polymeric low-k dielectric layer starts by depositing a protective layer composed of silicon nitride (SiN) or silicon carbide (SiC) on a substrate. A hydrophilic surface is produced across a top surface of the protective layer by performing a fast surface treatment that subjects the surface to an oxygen-containing plasma at a pre-selected low radio frequency power. An adhesion promoter coating layer is formed over the top surface of the protective layer. The coating layer has promoter molecules, each promoter molecule having at least one hydrophobic group and one hydrophilic group. The low-k dielectric layer is spin-on coated onto the coating layer. Formation of the hydrophilic surface alters an orientation of the adhesion promoter molecules to facilitate the hydrophilic group of each of the adhesion promoter molecules facing the hydrophilic surface while the hydrophobic group of the adhesion promoter molecules faces the low-k dielectric layer.
