Title: Dram and its manufacturing method
Inventor: ONO KEIICHI
IPC: H01L27/108
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To form the plate contact of a DRAM with COB(capacitor over bit line) structure stably and efficiently. SOLUTION: A cylindrical capacitor 15 is formed at a capacitor formation region I and at the same time two dummy patterns 15d that are electrically irresponsive are formed also at a plate contact formation region II. An etching stop layer 6d in formed is advance by a film that is common to a bit line 6 at the lower part of a space between the dummy patterns 15d. An interlayer insulation 16 is subjected to dry etching and at the same time each contact hole connected to a plate electrode 14, a diffusion layer 3, and a word line 4 is formed. The depth of a pair of plate electrode contact holes 21 is shallower than that of other holes but the contact holes 21 are formed to a proper depth since a plate electrode 14 with a slow etching speed is greatly exposed in the hole. Also, a contact area between the plate electrode 14 and a plate drawing electrode is increased.

Title: Blood ejection function-evaluating device
Inventor: OKA SUSUMU
IPC: A61B5/022
Filed: 1995-03-01
Abstract: PURPOSE: To provide a blood ejection function-evaluating device by which the blood ejection function of heart can precisely be evaluated. CONSTITUTION: A blood pressure evaluating curve is determined by arithmetically- operating successively a product of a size of peripheral side pulse sound and a delayed time of the peripheral side pulse sound to a mainstay side pulse sound which is determined by means of the delayed time determining means 61 according to pressure change of a cuff 10 in a blood pressure evaluating curve computing means 62, and the highest blood pressure and the lowest blood pressure are determined based on a sharply increasing point and a sharply decreasing point of the blood pressure evaluating curve in a blood pressure determining means 63.  Higher measurement accuracy can be obtained than usual blood pressure determination because the sharply increasing point and the sharply decreasing point are strengthened by a multiplication of the size of the peripheral side pulse sound and the delayed time in the blood pressure evaluating curve, thereby the influence of noise attributed to body motion is greatly removed, and thus the blood ejection function of a living body can precisely be evaluated in the blood pressure ejecting function evaluating device having a form of measuring blood pressure value before/after loading exercise load.

IPC: H01L21/3065
Filed: 1981-03-25
Abstract: PURPOSE: To increase proof stress against dry etching by implanting ions in approximately 1×10 13 W1×10 15 /cm 2  to a resist pattern.  
     CONSTITUTION: A PSG film 2 and a polymethylmethacrylate film 3 are applied onto a Si substrate 1 by approximately 1μm. The resist pattern 3 is manufactured through the irradiation of electron rays and development after baking. When Ar ions 4 are implanted in the whole surface, the unstable side chain sections of the film 3 are removed by the ions having high energy, stable principal chains are left, and the film 3 is partially carbonized. Accordingly, proof stress is increased against a shock by plasma, etc. When the PSG 2 is etched through reactive sputtering in C 4 F 8  while using the resist 3 as a mask, the mask 3 is hardly etched. Lastly, an excellent PSG pattern 2 is formed when the resist 3 is removed by O 2  plasma. The quantity of ions implanted differs slightly according to the kinds of resists, but approximately 1×10 13 W1×10 15 /cm 2  is effective, and the minute pattern is obtained with high accuracy.
