Title: Thin film forming equipment and thin film forming method
Inventor: FUJII SHINJI
IPC: H01L21/285
Filed: 1990-11-06
Abstract: PURPOSE:To improve the step coverage and denseness of a thin film to be formed, by a method wherein, when powder particles are deposited on a substrate to be deposited, said substrate is irradiated with laser light, and the powder particles are heated, fused, and fluidized. CONSTITUTION:Powder particles are deposited on a substrate 31 to be deposited. At this time, the substrate 31 is irradiated with laser light 29 generated by an ArF eximer laser light source 27, through a laser light irradiation window 28 (intensity is 0.5J/cm<2>). Thereby powder particles deposited on the substrate 31 can be fused and fluidized. The laser light irradiation time is made pulse type, and the pulse time width is made shorter than or equal to 100ns. Thereby the thickness of a reaction layer of Al and Si can be made thinner than or equal to 0.2mum. When the substrate 31 to be deposited is a silicon substrate, a junction part formed on the silicon substrate can be prevented from destruction.

Abstract: PURPOSE:To make it possible, when a power failure occurs, to clearly display the occurrence of a power failure and its content with only a single display element by displaying the occurrence of power failure by flickering a LED differently in accordance with the content of the failure. CONSTITUTION:CPU 51 of power supply controller 15, when detecting a power failure, initiates a timer in the controller 15, and carriers out the on/off control of LED 19. Further, when about two seconds pass, CPU 51 restarts the timer, and turns on LED 19 to inform the operator that reporting the error status starts. Next, the error status is represented with 4 bits, and when a bit indicates '1', it is lighting for long while '0' is lighting for short, and thus 4 bits light sequentially to display 15 types of power failures with a single LED 19. With this, the operator is informed clearly of the occurrence of a power failure and its content.
