A wafer processing method in which a wafer including devices on a front surface side is processed. The method includes a wafer-with-protective-component forming step of forming the wafer with a protective component through sticking the protective component formed of a resin that softens by heat to the front surface side by pressing and heating the protective component, a thickness measurement step of measuring a thickness of the protective component in the wafer with the protective component, and a grinding step of holding the wafer with the protective component by a chuck table and grinding a back surface side of the wafer until a thickness of the wafer becomes an intended finished thickness. In the grinding step, the thickness of the protective component measured in the thickness measurement step is subtracted from a total thickness of the wafer with the protective component to calculate the thickness of the wafer.

Wafer processing method

An electric circuit breaker device includes: an igniter; a projectile that is disposed in a movement path, the projectile formed to be movable by actuation of the igniter; and a conductor piece that forms one portion of a predetermined electric circuit, the conductor piece having both end portions connected to respective other portions of the predetermined electric circuit, the conductor piece having a first portion between both the end portions arranged to traverse the movement path. A sensor is connected to a first part positioned between both the end portions and to a second part that is between both the end portions and is different from the first part, the sensor configured to detect current flowing through the conductor piece between both the end portions, the sensor disposed to be integrated with the conductor piece. The actuation of the igniter is controlled, based on the current detected by the sensor.
