Abstract: An in-vehicle control device performs authentication using a variable authentication key when the authentication is requested upon executing a predetermined process involving communication with an external communication server, and executes the predetermined process and stores, as the variable authentication key, at least a part of information on the communication upon executing the predetermined process when the authentication using the variable authentication key is certified. As such, since the in-vehicle control device and the external communication server automatically certify each other's validity using the variable authentication keys, a user does not need to certify the validity, thereby improving the efficiency of the authentication for the communication between a vehicle and the external communication server.

Abstract: A semiconductor device production system using a laser crystallization method is provided which can avoid forming grain boundaries in a channel formulation region of a TFT, thereby preventing grain boundaries rom lowering the mobility of the TFT greatly, from lowering ON current, and from increasing OFF current. Rectangular or stripe pattern depression and projection portions are formed on an insulating film. A semiconductor film is formed on the insulating film. The semiconductor film is irradiated with continuous wave laser light by running the laser light along the stripe pattern depression and projection portions of the insulating film or along the major or minor axis direction of the rectangle. Although continuous wave laser light is most preferred among laser light, it is also possible to use pulse oscillation laser light in irradiating the semiconductor film.
