Title: Method for dividing wafer
Inventor: MORITA HIDEKI
IPC: B23K26/38
Filed: 1990-09-07
Abstract: PURPOSE:To cut a wafer without generating contaminating materials by forming grooves of the width smaller than a laser beam diameter on the wafer along desired lines to be cut, then irradiating these grooves with a laser beam, thereby dividing the wafer. CONSTITUTION:The grooves 2 are formed along the desired lines to be cut of the wafer W. The grooving is executed by photolithography or chemical dry etching, etc., preferably to about 2 to 3mum groove width. Thermal stresses act on the irradiated position and a crack C is generated in the bottom of the groove 2 if the positions near the end edge of the wafer W is irradiated with the laser beam L. The crack C is guided and progressed along the groove 2 when the position irradiated with the laser beam L is moved along the groove 2. The dividing of one line is thus completed. The generation of the contaminating materials by evaporation and dissolution is obviated and the characteristics of devices of LSIs and ICs, etc., on the wafer are not adversely influenced.

Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To efficiently to use an on-gauge portion by counting the number of turns of a metallic sheet to be delivered, calculating the outside diameter of an off-gauge portion on the inner circumference side from the outside diameter value when the remaining number of turns is a specified value, plate thickness, and remaining number of turns, and deciding the remaining number of turns to start deceleration based on the value, thus stopping the reel. SOLUTION: The number of turns of a metallic sheet 20 when a metallic rolled coil 2 is wound on a pay-off reel 1 is recorded as the first number of turns in a controller. The number of revolutions of the pay-off reel 1 is detected by a counter, and the controller calculates the difference between the first number of turns and the detected value as the remaining number of turns. When the remaining number of turns reaches the specified value, the outside diameter of the off-gauge portion on inner circumference side is calculated from the outside diameter value of the metallic rolled coil 2, thickness of the metallic sheet 20, and the remaining number of turns.  Length necessary for decelerating/stopping is added to the outside diameter to make the deceleration starting diameter, and when the remaining number of turns becomes the number of turns equivalent to the deceleration starting diameter, the deceleration of the pay-off reel 1 is started.
