Abstract:
Wafers are prevented from getting damaged on delivery thereof from a sucking and carrying device to a table. A wafer before planarization sucked and held by a sucking board is positioned above a table. Next, wafer is vacuum-attracted by the table, and the table is moved upward by that attraction power in a direction to suck the wafer so as to vacuum-suck it on the table. Subsequently, the wafer is sucked and held only by the table by releasing the sucking and holding thereof by the sucking board.
Abstract:
A workpiece processing device (10) for processing a workpiece (60; 20, 36) comprises: a surface protection film peeling means (50) for peeling a surface protection film (110), which is adhered to a front surface (21) of a workpiece, with a peeling tape (4); a bar code adhering means (11) for adhering a bar code (65) corresponding to the workpiece to the workpiece; and a movable support table (72) for supporting the workpiece. A peeling operation for peeling the surface protection film conducted by the surface protection film peeling means and a adhering operation for adhering a bar code conducted by the bar code adhering means are given to the workpiece while the workpiece is being supported by the support table. Due to the foregoing, it is possible to avoid failures when adhering the bar code to the workpiece, such as a wafer. The bar code adhering means may adhere the bar code, which corresponds to character information of the workpiece read out by an optical reading means, to the workpiece.

Abstract:
A film peeling device for peeling a film (11) adhered to a front surface of a wafer (20), on the back surface of which a dicing tape (3) is adhered, the wafer is integrated with a mount frame (36) into one body, comprises: a movable table (31), which can be moved horizontally to support the wafer and the mount frame while the surface protection film is being directed upward; a covering means (80) for covering an adhesive face (3a) of the dicing tape, which is exposed between the mount frame and the wafer at one end (28) of the wafer; and a adhering means (46) for adhering a peeling tape (4) to the film at the end of the wafer. The film is peeled from the front surface of the wafer by moving the movable table from the other end (29) of the wafer to one end after the peeling tape has adhered. Due to the foregoing, while the peeling tape is being prevented from adhering to the dicing tape, the film can be peeled from the front surface of the wafer in a shorter period of time.
Abstract:
A method of calculating a quantity of light by measuring, by using an adhering force measuring unit (71), the adhering force of an ultraviolet light-curable tape (11 or 21) relying upon the quantity of ultraviolet light with which the ultraviolet light-curable tape is irradiated from an ultraviolet light irradiation unit (61), and calculating, by using a calculation unit, the quantity of ultraviolet light corresponding to a predetermined adhering force, from the measured adhering force of the ultraviolet light-curable tape, and a device therefor. The predetermined adhering force may have been stored in advance in the storage unit or the predetermined adhering force may be determined in advance relying upon at least either one of the kind of the ultraviolet light-curable tape or the elapsed time of the ultraviolet light-curable tape. Then, the quantity of light necessary for the ultraviolet light-curable tape that is used is automatically calculated to avoid a problem caused by an insufficient quantity of light or an excess quantity of light.
Abstract:
There are provided a wafer processing method comprising the steps of grinding an underside (21) of a wafer which is provided, on its front surface (29), with a plurality of semiconductor devices (10); polishing a ground surface (22) formed by the grinding operation; and carrying out a plasma-processing for a polished surface (23) formed by the polishing operation under a predetermined gaseous atmosphere in a plasma chamber, to form an oxide layer on the polished surface, and a wafer processing method comprising the steps of carrying out a first plasma-processing for a polished surface formed by the polishing operation under a first gaseous atmosphere (CF4 or SF6) in a plasma chamber, to clean the polished surface; and carrying out a second plasma-processing for the polished surface after the cleaning operation under a second gaseous atmosphere (O2) in the plasma chamber, to form an oxide layer on the polished surface, and a wafer processing apparatus for carrying out these methods. Thus, the wafer can be processed while the occurrence of an electrical failure in a thin wafer is restricted.
