Title: Semiconductor integrated circuit device and manufacturing method thereof
Inventor: NOSE FUJIAKI
IPC: H01L23/12
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To decrease the rigidity of an element mounting portion of an element mounting board, so as to reduce the stress applied onto a bump connection part of a semiconductor element and improve connection reliability of the bump connection part of the semiconductor element, by forming the element mounting portion of the element mounting board with a thickness smaller than that of a non-element mounting portion. SOLUTION: In an element mounting board 2 for supporting a semiconductor chip 1, an element mounting portion 2a is formed with a thickness smaller than that of a non-element mounting portion 2b. Thus, the rigidity of the element mounting portion 2 in the element mounting board 2 may be decreased. Therefore, when BGA is heated or cooled to cause the element mounting board 2 to expand or contract, the element mounting portion 2a may be deformed in accordance with the degree of deformation of the semiconductor chip 1, since the element mounting portion 2a having a coefficient of thermal expansion greater than that of the semiconductor chip 1 has flexibility. As a result, the stress applied onto a bump connection part 3a may be reduced, and connection reliability of the bump connection part 3a may be improved.

Abstract: PURPOSE:To enable sensitiveness of a photoresist to be controlled with good accuracy for improving size accuracy of a photoresist pattern by providing a large number of holes for applying gas, whose temperature is controlled on the hot plate surface, to the rear of a wafer. CONSTITUTION:A wafer 1 is heated, while a temperature is controlled with a heater 3 for wafer heating installed in the inside of a hot plate, for being conveyed. At the same time, dry air heated by the heater inside a dry air lead-in tube 2 for wafer heating going through inside the hot plate hits on the rear of the wafer 1 through a large number of holes on the hot plate. Then dry air blown out from a dry air nozzle for purge purges a solvent evaporated from a photoresist but without coming round because dry air for wafer heating is blowing out from the rear of the wafer 1. Accordingly, the wafer is not cooled by dry air for purge so that the temperature can be controlled with good accuracy by heating from the rear.

Title: Reflection type optical sensor
Inventor: SHINDO MIKIO
IPC: G01V8/12
Filed: 1985-12-17
Abstract: PURPOSE:To improve the S/N in case of detecting an original, by inclining and disposing optical axes of a light emitting element and a light receiving element against a normal of the surface of a transparent plate. CONSTITUTION:A light beam R1 from a light emitting element 3 irradiates an original 1 through glass 2, and a part of a light beam R2 which has been reflected irregularly by the surface of the original 1 is made incident on a light receiving element 3b through the glass 2 again. In this case, the light beam R1 from the element 3a is reflected by the incident surface of the glass 2, as well, but as for a sensor 3, its optical axis is placed in a state that it has been inclined by a prescribed angle thetaagainst a normal of the surface of the glass 2, therefore, a reflected light R3 is reflected in the direction being different from the element 3b, and not made incident on the element 3b, therefore, it does not become a noise. Also, even when a light beam is emitted into the air from the glass 2, it is reflected by the inside surface of the glass 2, but this reflected light R4 is not made incident on the element 3b either. Accordingly, against a light quantity S of the reflected light R2 of the original 1 in the element 3b, it does not occur that a light quantity N of the reflected rays R3, R4 from the glass 2 increases, therefore, the S/N in case of detecting an original is improved.
