Abstract: To improve the reliability and yield of a thin-type semiconductor device as used for a stack-type flash memory, the semiconductor device is manufactured by upheaving each of semiconductor chips (semiconductor devices) obtained by dicing a semiconductor wafer on an adhesive sheet from a backside via the adhesive sheet using an upthrow jig to which ultrasonic vibration is applied so as not to break through the adhesive sheet, and by picking up each semiconductor chip.

Abstract: In an RFID (radio frequency identification) tag comprising an antenna formed of a conductive paste containing conductive filler like silver flakes on a base member, and an RFID chip connected to the antenna, the present invention cures a pattern of the antenna formed of the conductive paste, and then connects the RFID chip to the antenna with thermoplastic resin contained in the conductive paste by heating bump electrodes of the RFID chip in contact with the antenna. According to the present invention, Since the bump electrodes of the RFID chip and the antenna are connected to each other and establish sufficient electrical conduction therebetween without providing an anisotropic conductive sheet or the like therebetween, a highly reliable RFID tag is supplied at a low cost.

Abstract: In an apparatus for separating semiconductor chips, a semiconductor wafer stuck to an adhesive sheet with its silicon mirror surface facing downwards is sucked as a whole through its circuit surface side by means of a sucker plate capable of sucking the whole of wafer. In order to separate the sheet from a frame fixing the sheet while the sheet being sucked, the sheet is cut by a cutter edge so as to be separated from the frame. To separate the sheet from the wafer, the wafer top surface is guided by a guide plate having a tip angle of 15° and by causing the sheet to profile the tip of the guide plate, the sheet is peeled off in a direction making an angle of 45° to the dicing direction on the wafer.

Abstract: Electric conductor patterns including antenna coils are formed on one surface of a film. Electronic components are fixed onto the film by a temporary fixing material. A cover film is laminated on the film so that the electrically conductive patterns and the electronic components are covered with the cover film. Simultaneously with the lamination, the electronic components are connected to the electric conductor patterns.

Abstract: There are disclosed a solder bump forming method and an apparatus therefor, which achieve a high reliability, and an electronic part, produced by this method and this apparatus, is also disclosed. For each of the step of arraying solder balls, the step of supplying a flux, and the step of mounting the solder balls on a board, it is checked whether or not any solder ball is omitted, and the process is conducted while confirming the condition of the operation, thereby enhancing the reliability and also preventing defective products from being produced.

Abstract: A surface of a wafer (semiconductor substrate) is subjected to grinding by rotating it and bringing it into contact with a rotating grinding wheel. The grinding wheel is rotated in a first direction at a rotating speed N1. The wafer is rotated in a second direction which is opposite to the first direction at a rotating speed N2, wherein a value of N2/N1 is in the range of 0.006 to 0.025. The wafer is then carried from the grinding process to a dicing process while being maintained in a horizontal position by using a wafer handling jig to prevent the breakage of the wafer. A flash etching process may also be used at the end of the grinding process.

Abstract: The present invention is to define an enclosed space by covering a holder which can hold numerous minute particles, and introduce a fluid into the enclosed space to stir up the numerous minute particles within the enclosed space with a turbulent flow of the fluid so that the minute particles are placed in and held by the holder After stirring up and loading the minute particles in the holder, the fluid is introduced into the enclosed space again to recover the remaining minute particles which have not been held by the holder. The number of minute particles required for one cycle of the loading operation are taken out by moving a particle push-up shaft vertically, having a recess at the distal end thereof, within a stocker which stores a large number of minute particles, and then delivered to the enclosed space with the fluid.
