Title: Method of making a multilayer circuit board
Inventor: YAMAZAKI KOZO
IPC: H05K3/46
Filed: 2000-01-04
Granted: 2002-05-21
Abstract: In a method of making a multilayer circuit, a surface of an organic resin precursor layer is roughened when the organic resin precursor layer is in a semi-cured, state. An electroless plated layer constituting part of the conductive layer is formed on the roughened surface of the semi-cured organic resin precursor layer and heat-treated simultaneously with heat treatment for completely curing the semi-cured organic resin precursor. By this, the adhesion between the insulating organic resin layer and the conductive layer can be maintained high, thus making it possible to prevent peeling or floating of the conductive layer from the insulating organic resin layer assuredly. The heat treatment of the electroless plated layer together with the organic resin precursor layer is effective for enabling the etching for forming the conductive layer to be accurate and therefore enabling to form the conductive layer of a predetermined pattern accurately. Further, the surface of the insulating organic resin layer is roughened in such a manner that the roughness of the surface of the insulating resin organic resin layer is X μm Rz where Rz is a ten-point average roughness according to JIS-B-0601. The electroless plated layer is formed so as to be Y μm thick. The surface roughness X μm Rz and the thickness Y μm have the relation of Y ≤ X/3. By this, the surface roughness of the electroless plated layer can be nearly equal to that of the insulating organic resin layer, whereby it becomes possible to attain a sufficient adhesion between a plating resist layer and the electroless plated layer and therefore it becomes possible to prevent separation or floating of the plating resist layer from the electroless plated layer assuredly.

Title: Method and device for processing filament yarn, and the application of this device
Inventor: BUCHMUELLER PATRICK
IPC: D02G1/16
Filed: 2000-03-03
Granted: 2003-06-21
Abstract: The invention relates to a method for processing spun and prepared yarn in a processing body.

Title: Method to form a smooth gate polysilicon sidewall in the fabrication of integrated circuits
Inventor: BALASUBRAMANIAM PALANIVEL
IPC: H01L21/28
Filed: 2000-03-17
Granted: 2001-05-28
Abstract: A method for forming gate structures with smooth sidewalls by amorphizing the polysilicon along the gate boundaries is described. This method results in minimal gate depletion effects and improved critical dimension control in the gates of smaller devices. The method involves providing a gate silicon oxide layer on the surface of the semiconductor substrate. A gate electrode layer, such as polysilicon is deposited over the gate silicon oxide followed by a masking oxide layer deposited over the gate electrode layer. The masking oxide layer is patterned for the formation of the gate electrode. An ion implantation of silicon or germanium amorphizes the area of the polysilicon not protected by the masking oxide mask and also amorphizes the area along the boundaries of the polysilicon gate. Thereafter, the amorphized silicon is then removed by an anisotropic etch leaving a narrow area of amorphized silicon on the gate electrode sidewalls under the edges of the masking oxide mask completing the gate structure having smooth sidewalls.
