Title: Manufacture of semiconductor device
Inventor: SUZUKI SATOSHI
IPC: H01L21/265
Filed: 1994-05-20
Abstract: PURPOSE:To make uniform various kinds of characteristics at a MOS structure part within a wafer by partially eliminating an insulation film at a position where ions are scheduled to be implanted for the film thickness direction and implanting ions for forming an impurity region at the position where ions are scheduled to be implanted. CONSTITUTION:After a gate electrode 4 is formed, a gate insulation film 3 at a position where ions are scheduled to be implanted is made thinner than by partial etching for the direction of film thickness. At this time, a gate insulation film below the gate electrode 4 remains as a general thick film. After that, ions are implanted at the position where ions are scheduled to be implanted to form an impurity region. The acceleration voltage for implantation can be reduced from general conditions, thus enabling ions to pass through a gate insulation film and preventing channeling from occurring due to the reduction in an acceleration voltage. Therefore, various kinds of characteristics at the MOS structure part can be made uniform within the wafer and yield can be improved.

Filed: 1980-08-04
Abstract: PURPOSE:To prevent a video signal from having a flicker by alternating a transfer pulse in the 1st phase and that in the 2nd one at intervals of one or a few fields. CONSTITUTION:The vertical transfer pulses phi'V1T and phi'V2T of driving clock pulses phi'V1 and phi'V2 are inverted in phase at intervals of one field TV. Therefore, when the same read pulse is applied with the driving clock pulses phi'V1 and phi'V2, their vertical transfer pulses phi'V1T and phi'V2T are inverted in phase at invervals of one field TV, so integration time of nodes n1 and n2 at the same bias potential are both one frame Tf equally. Further, a photodiode applied with the read pulse phi'V1R of the driving clock pulse phi'V1 and that applied with the read pulse phi'V2R of the driving clock pulse phi'V12 have the equal amounts DELTAV'R1 and DELTAV'R2 of light signals integrated in the period of one frame Tf.

Filed: 1982-06-23
Abstract: PURPOSE:To make it possible to join a certain process and the next process and thereby realize a consistent manufacturing system by compensating for fluctuation in a certain process in the next process. CONSTITUTION:After applying a resist 52 on a polycrystalline Si formed in the process PN-1, it is exposed after matching, a film 52 is developed and is printed. Thereafter the film 52 is peeled and a substrate is sent to the next inspection process. Here, for example, it is presumed that a processing width L is deviated positively as 2.1mum, although within the scope of specification, from the center value 2mum of the processing width L. This wafer is within the scope of specification and therefore it is sent directly to the process PN+1 where the As ion is implanted in order to form the source 53 and drain 54. In this case, however, the data of processings after the inspection process are transmitted to the process PN+1 and thereby adjustment of thermal processing lamp is carried out automatically so that the thermal diffusion of 0.1mum in the lateral direction is executed and thereby the value of polycrystalline Si gate electrode width L which is the same as that of the center value can be obtained. Thereby, fluctuation in the process PN can be compensated in the process PN+1.

Title: Prevention of vibration of ground due to driving of pile
Inventor: TAKEE TAKASHI
IPC: E02D13/10
Filed: 1981-07-10
Abstract: PURPOSE: To exactly prevent the vibration of the ground due to the driving of pile by a method in which the energy of driving of pile is stored in a pressure-storing medium inside a device and then gradually released for a comparatively long period of time immediately after the driving of the pile is ended.  
     CONSTITUTION: When a drop hammer 36 is dropped and strikes an anvil 29, a ram 26 goes down to raise the pressure of a pressure-storing medium inside a generating chamber 25, a valve plate 13 is pushed down against a spring 15, and the pressure- storing medium inside a pressure-storing chamber 10 is pressurized. Then, when a pressure difference between the generating chamber 25 and the pressure-storing chamber 10 is eliminated, the valve plate 13 is pushed up by the spring 15 and a valve hole 8 is closed. Upon completion of the driving, the pressure-storing medium gradually flows back into the generating chamber 25 through the valve hole 11, a communication hole 9, and valve hole 8 by its volumetric expansion for a comparatively long period of time. Thus, a power-accumulating action against the dynamical stability of the ground is applied through the pile after the ending of the driving in such a way as to damp the dynamical stability of the ground, whereby preventing the vibration of the ground.
