In a manufacturing method of a semiconductor device, a semiconductor chip is sealed with a resin, and then a laser is applied to remove the resin so that a part of the semiconductor chip is exposed. The semiconductor chip is made of a material that has a lower absorptivity of the laser than the resin and is not melted by the laser. The laser has a wavelength that passes through the semiconductor chip and has a lower absorptivity in the semiconductor chip than in the resin. The laser is applied to the resin from a side adjacent to one of plate surfaces of the semiconductor chip, so that the resin sealing the one of the plate surfaces is sublimated and removed and at least a part of the resin sealing the other of the plate surfaces is subsequently sublimated and removed by the laser having passed through the semiconductor chip.

Semiconductor device and method for manufacturing the same

An antitheft apparatus for a vehicle has an inertia sensor, which is also used for an anti-lock braking system. An electronic control unit receives output signals from the inertia sensor and determines a possible vehicle theft when a detected vehicle condition (for example, vehicle acceleration) is larger than a threshold value.
