Title: Production of field effect transistor
Inventor: MATSUSHITA SHIGEHARU
IPC: H01L21/338
Filed: 1991-02-19
Abstract: PURPOSE:To allow application of the title production of various semiconductor devices by forming a source/drain area a symmetrically to a certain gate bearing on a wafer and improving the performance of a FET. CONSTITUTION:Impurities are doped by using a gate 5 composed of two or more layers allowing under-cut, and source areas and drain areas are formed on the both sides of the gate allowing self-alignment. One side wall of the drain or the source is covered with resist 9, other exposed side wall is under-cut, and the resist 9 is removed to be re-under-cut. Thus, the quantity of the under- cut of the drain and the source is independently controlled and an asymmetrical source/drain structure is formed.

Title: Section measurement
Inventor: SHINGU TERUO
IPC: H01J37/28
Filed: 1987-03-04
Abstract: PURPOSE:To measure a correct aerial view with limited computing errors with correction by a data on a reference line as required, by actually measuring a Z-way relative position on a starting line to calculate X-way profiles with the resulting value as reference. CONSTITUTION:First, X-axis profiles are measured. For example, a straight line 15 is scanned to measure the profile thereof. Here, an arithmetic processing is carried out along the X-axis using a Z-axis measured value Za obtained on a starting line 12 at the point A (X0, Y1) as initial value of integration. When approaching a reference line 13 from the starting line 12, the profile is corrected by a Z-way measured value Zb at the point B (Xm, Y1) as obtained on the reference line 13. Likewise, when approaching the point C from the point B, the profile is corrected by a Z-axis measured value Zc at the point C. Thus, when the measurement of the profile 15 is ended in this way, an electron beam is returned to a sampling point (X0, Y2) to scan an straight line 16 parallel with the X-axis containing Y=2 whereby the corresponding profile is determined while being corrected by the reference lines 13 and 14.

Title: Reproducing system of pcm signal
Inventor: HOSHINO TAKASHI
IPC: H04B14/04
Filed: 1983-03-24
Abstract: PURPOSE:To correct codes by writing the data showing errors immediately before reading is over with each memory region in order to restore an array of data blocks and then writing said data to the memory region before new data is written. CONSTITUTION:In a read mode the error pattern data is written to each memory region in field memories 23 and 24 immediately after the data is read out. No data which is once read out remains, and the error pattern data which receives a code correction without fail is used instead to a data block containing an error when the data block of the next field period. Therefore the PCM sound data of the preceding field period which is not erased is never used. As a result, the sound signal delivered from a D/A converter 25 contains no abnormal waveform that produces abnormal sounds.
