Only a region where TFTs constituting a high-performance circuit will be disposed in a precursor semiconductor film PCS on an insulating substrate GLS with an insulating layer UCL serving as an undercoat is irradiated with a first energy beam LSR so as to be poly-crystallized while growing crystal grains laterally. The implantable medical device includes a recharge module that regulates the recharging process of the implantable power source using closed-loop feedback control. An efficient, reliable method and mechanism operate to discriminate between successful and unsuccessful projectile launch and use that information to arm or not arm the projectile.
