Title: Semiconductor device
Inventor: ITO MASAHIKO
IPC: H01L23/29
Filed: 1985-05-10
Abstract: PURPOSE:To improve moisture resistance and corrosion resistance without imparing the functions of a semiconductor device at all, only by converting a flame retardant of a sealing resin into an Sb(V) compound. CONSTITUTION:In many cases, Sb2O3 is used as a flame retardant of a sealing resin. The Sb2O3 is hard to be dissolved into water. The moisture is transmitted through the resin and reaches the surface of an element. Cl is present in the moisture. Under the state of high temperature, a minute amount of Sb<3+> is dissolved. Corrosion of Al electrodes is accelerated in the state both Cl and Sb<3+> are present. When Sb2O5 as a flame retardant, which includes Sb of quinquevalence, is used, corrosion of the Al electrodes and Al wirings can be remarkably reduced. Sb compounds of quinquevalence, which are not dissolved or are hard to be dissolved in water, such as K [Sb(OH)6] and the others are similarly effective, in addition to the Sb2O5. The corrosion is reduced to a larger extent in comparison with the case only Cl ions are used. Thus the highly reliable device is obtained.

Title: Resist coater
Inventor: SAKAMOTO HIROTO
IPC: B05C11/08
Filed: 1990-04-13
Abstract: PURPOSE:To obtain a resist coater which always realizes a satisfactory coating process by measuring a waiting time after stopping the supply of resist fluid by a resist fluid supply mechanism, operating the resist fluid supply mechanism and disposing the preset amount of resist fluid from a resist supply nozzle when the waiting time has exceeded a preset time. CONSTITUTION:This resist coater measures a waiting time after stopping supply of resist fluid by a resist fluid supply mechanism 5. This waiting time is collated with the times T1, T2 previously stored in a memory 10. When the waiting time has exceeded the preset time T1, the resist fluid supply mechanism is operated immediately after the preset time, for example, or before the next resist coating with an instruction from a computer 10 after the preset time and the preset amount of resist fluid within the end portion of a resist supply nozzle 6 is disposed therefrom into a waste fluid collector 8. When the waiting time is longer, the time T2 is not limited only one timing and is set to intermittent plural timings. Therefore, if the waiting time until the next resist coating process becomes longer, it can be prevented that the resist fluid having a higher viscosity is supplied on the substrate to be processed and the resist solution is solidified within the resist supply nozzle.
