Abstract: Methods for forming flip chip interconnection, in which the bump interconnect is defined at least in part by an underfill. The underfill includes a material that is thermally cured; that is, raising the temperature of the underfill material can result in progressive curing of the underfill through stages including a gel stage and a fully cured stage. According to the invention, during at least an early stage in the process the semiconductor chip is carried by a thermode, which is employed to control the temperature of the assembly in a specified way. Also, flip chip interconnections and flip chip packages made according to the methods of invention.

Abstract: A method for removing an oxide layer such as a natural oxide layer and a semiconductor manufacturing apparatus which uses the method to remove the oxide layer. A vertically movable susceptor is installed at the lower portion in a processing chamber and a silicon wafer is loaded onto the susceptor when it is at the lower portion of the processing chamber. The air is exhausted from the processing chamber to form a vacuum condition therein. A hydrogen gas in a plasma state and a fluorine-containing gas are supplied into the processing chamber to induce a chemical reaction with the oxide layer on the silicon wafer, resulting in a reaction layer. Then, the susceptor is moved up to the upper portion of the processing chamber, to anneal the silicon wafer on the susceptor with a heater installed at the upper portion of the processing chamber, thus vaporizing the reaction layer. The vaporized reaction layer is exhausted out of the chamber.

Abstract: Provided is a display module cabinet having the slim front frame width and improved design and keeping strength against breakage. In addition, provided is the cabinet having the elegant rear cover, which reduces costs and time in assembling the display device. The cabinet includes a front cover and a rear cover. The front cover includes a front frame portion defining an opening and a side frame portion extended backward from the front frame portion and including a thick portion and a thin portion that are sequentially formed. The rear cover includes a rear portion and a peripheral portion extended forward from the rear portion and including a thick portion and a thin portion that are sequentially formed. A protruding portion is extended backward from the thick portion of the front cover so as to be interposed between the thin portion of the rear cover and the display module.

Abstract: A cleanling apparatus for removing contaminants from the surface of a substrate includes two parts: one which produces an aerosol including frozen particles and directs the aerosol onto the surface of the substrate to remove contaminants from the surface by physical force, and another part in which a fluid including a gaseous reactant is directed onto the surface of the substrate while the surface is irradiated to cause a chemical reaction between the reactant and organic contaminants on the surface, to chemically removing the organic contaminants. In the method of cleaning the substrate, the physical and chemical cleaning processes are carried out in a separate manner from one another so that the frozen particles of the aerosol are not exposed to the effects of the light used in irradiating the surface of the substrate. Therefore, the effectiveness of the aerosol in cleaning the substrate is maximized.
