Title: Formation of capacitor
Inventor: SAITO MASAKI
IPC: H01L27/108
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To enable filling of a capacitor with a void-free insulating film, and prevent damage to the capacitor due to gas expansion in a void and reduction in yield of a semiconductor device due the damage. SOLUTION: On a substrate 30 covered with a first polysilicon film 34 constituting a bottom part of a lower electrode of a cylinder capacitor, a silicon oxide film 35 having an impurity concentration gradually lowered from the bottom to the surface is formed. The silicon oxide film 35 is patterned by dry etching, thus forming a silicon oxide pattern 35a. An exposed surface of the silicon oxide pattern 35a is wet-etched, until the sidewall of the silicon oxide pattern 35a becomes substantially perpendicular to the surface of the substrate 30 and a native oxide on an exposed surface of the first polysilicon film 34 is removed. After that, a second polysilicon film constituting a lateral part of the lower electrode of the cylinder capacitor is formed on the substrate 30 in such a state as to cover the silicon oxide pattern 35a.

Filed: 1981-11-16
Abstract: PURPOSE:To copy information immediately from the last frame, by adding the last frame marks in a line in addition to lines of frame marks and the first frame marks. CONSTITUTION:On a microfilm 11, frame marks MK for individual frames K, the first frame marks MC for the first frames of respective frame groups KG, and the last frame marks MD for the last frames of respective frame groups are added in different lines in the longitudinal direction of the mirofilm. In case that an information group (B1, B2, and B3) of one unit is copied, the last frame mark MD of the frame group KG is detected by a reader/printer, and the copy is started immediately from the last frame K after information B3 of the last frame is recorded, and information B3, B2, and B1 are copied in order. In the microfilm where the last frame marks are not added, time is wasted and the operativity is low because the microfilm must be returned by an extent corresponding to one frame after detection of the start frame mark of the next frame group.

Title: Recognizer for handwritten character
Inventor: YOSHIKAWA TAKATOSHI
IPC: G06K9/66
Filed: 1985-08-20
Abstract: PURPOSE:To attain a learning function based on variance data intrinsic to a writer by obtaining this data for each partial character pattern serving as a component element of a character recognized mistakenly in case the result of recognition is wrong. CONSTITUTION:A writer supplies a character to a tablet handwriting input part 1 in a correct order of strokes. Thus a stroke recognizing part 2 obtains normalized stroke data and this data is recognized by a stroke dictionary part 6. Thus a basic stroke code is obtained. These stroke data and code are separated from each other by a partial character pattern recognizing part 3. Then the partial character pattern code is obtained by a partial character pattern dictionary part 7. These candidate groups are compared with each character of a character pattern dictionary part 8 by a character pattern recognizing part 4 to be specified and delivered to a display part 5. When the character pattern is recognized mistakenly, a partial character pattern variance detecting part 10 compares the normal pattern with the candidate groups of partial character patterns recognized mistakenly for detection of the variance data intrinsic to the writer. This variance data is stored in a partial character pattern variance dictionary 9. Thus the correct recognition is possible after the variance data on the writer is once stored even if a character is supplied in a wrong order of writing strokes.
