Title: Method for removing carbon-rich particles adhered on a copper surface
Inventor: TSAI TENG-CHIUN
IPC: H01L21/304
Filed: 2000-12-06
Granted: 2003-03-21
Abstract: A method for removing carbon-rich particles adhered on a copper surface, especially on a copper surface of a copper/low k dielectric dual damascene structure is provided. A barrier layer and a barrier-CMP stopping layer are formed between the copper layer and the low k dielectric layer of the dual damascene structure. After a Cu-CMP process and a barrier CMP process, a chemical buffing polishing process using an acidic aqueous solution under a downward force of about 0.5 to 3 psi is performed to remove carbon-rich particles adhered on the exposed copper surface. The carbon-rich particle is generated from the low k dielectric layer with at least 90% carbon element being exposed due to dishing phenomenon of the copper layer, which is then polished during the Cu-CMP process and the barrier CMP process and thus produces many carbon-rich particles. Finally, a post-CMP cleaning step is carried out to remove residual impurities on the exposed copper surface. Alternately, a first chemical buffing polishing process using an acidic aqueous solution is performed after the Cu-CMP process, and a second chemical buffing polishing process using an acidic aqueous solution is performed after the barrier CMP process. These two chemical buffing polishing processes are used to remove the carbon-rich particles on the copper surface.

Abstract: The invention provides a design for fingerprint recognition chip whose manufacturing method fully complies with the IC fabrication process by using the temperature difference sensing concept to obtain the fingerprint pattern. Using temperature of human body as live creature recognition concept, a temperature gradient is generated by contacting fingerprint wave peak of finger with a sensor. The sensor converts the temperature gradient into electric signal such that the fingerprint recognition chip including multiple sensors aligned in form of 2-D matrix can acquire the electric signal output of fingerprint wave peak contour to achieve fingerprint recognition goal. The sensor structure includes a silicon substrate, an oxide layer formed on the substrate as the heat insulation structure, at least a thermopile formed by serially connected thermocouples, wherein the hot contact area of the thermopile is located at the central portion of the field oxide layer and the cold contact area of the thermopile is located on the thin oxide layer surrounding the field oxide layer; and a heat conduction tube structure consisting of at least a conductor connection line layer and at least a dielectric hole block metal fabricated between the central portion of the field oxide layer and passivation layer closest to surface. The signal read circuit of the fingerprint recognition chip employs improved dynamic memory signal read structure using digital method to output every sensor signal. Each sensor is equipped with a transistor switch. When the bit line selects the transistor switch (ON), the sensor voltage is outputted from bit lines to achieve the output of 0 and 1 digital signal via a comparison of a comparator between the bit line output and the output voltage of mute sensor in the end of the neighboring bit lines. The signal output is 1 when fingerprint wave peak contacts the sensor, otherwise, is 0 so as to acquire the digital hot image of fingerprint for fingerprint recognition.

Granted: 2003-01-01
Abstract: The present invention provides an apparatus and a method for compensating critical dimension deviations across a photomask. In this method, a photomask is partitioned into a plurality of regions. A critical dimension is then measured for each of the regions in the photomask. Based on the measured critical dimensions, a deviation map is generated to map deviation of the critical dimension from a target dimension for each of the regions in the photomask. From the deviation map, an amount of actinic radiation needed to be attenuated to compensate for the critical dimension deviation from the target dimension is determined for each of the regions of the photomask. Based on the determined attenuation amount of actinic radiation, the transmission of the actinic radiation through each of the regions in the photomask is attenuated such that the critical dimension deviation is compensated to the target dimension for each of the regions in the photomask.
