Filed: 1985-10-21
Abstract: PURPOSE:To obtain the titled semiconductor device of high reliability at a high yield rate by a method wherein a process, in which a high density impurity layer is formed on a scribe- lined region, is included in the initial process, and the thermal distortion generated by the temperature difference between the high impurity density region and the low impurity density region of an active element region and a passive element region is reduced in the heat treatment process wherein a short period annealing method (RTA) is used. CONSTITUTION:After an N-type collector region 5 has been formed on a silicon oxide film 2, an integrated circuit is formed in accordance with a planar process. An ion implanting method is used for the formation of an active element necessary for a shallow junction. Then, an RTA method with which a high temperature short-period heat treatment can be performed is used in order to recover activation and crystallizability after ion implantation. At this time, the rate of temperature rise of a low density impurity region and a high density impurity region is different due to the dependency of free carrier density of infrared ray absorption coefficient, and a thermal distortion is generated. As a result, if the area of the activated high density impurity region is increased in the initial process, the difference in temperature rising rate is reduced by providing a new high density impurity region especially on a scribe-lined region, the internal part of a wafer can be heated up uniformly, and the thermal distortion of the semiconductor device can be reduced.

Title: Discharge lamp lighting device
Inventor: NORO HIROSHI
IPC: H05B41/18
Filed: 1993-09-22
Abstract: PURPOSE:To reduce dispersion of a high voltage pulse by restricting charge voltage of a capacitor before inverting a rectangular wave, and controlling a charge quantity to the charge/discharge capacitor per half cycle. CONSTITUTION:At the time of inverting a rectangular wave, since both end voltage VS1 of a pulse driving voltage element S1 is higher than breakover voltage of the element S1 due to a potential difference by a charge accumulated in a charge/discharge capacitor C2 and a divider capacitor C3, the element S1 is turned on. Then, the capacitor C2 is discharged, to equalize voltages of the capacitors C2, C3, and the element S1 is turned off. Here by not charging the capacitor C2, voltage applied to the element S1 is OV until the rectangular wave is inverted, and also the element S1 is turned on/off only one time per half cycle, to control a charge quantity to the capacitor C2. Dispersion of pulse generating number of times and pulse generating phase is thus eliminated.
