Title: Manufacture of semiconductor device
Inventor: SHIMIZU YUJI
IPC: H01L21/316
Filed: 1990-10-04
Abstract: PURPOSE:To realize a high integrity by a method wherein a silicon oxide film is selectively etched to form a recess and a silicon nitride film is selectively buried in the recess and a semiconductor substrate is subjected to thermal oxidation by using the silicon nitride film as a mask. CONSTITUTION:After a polycrystalline silicon film 3 and a silicon oxide film 2 are etched by dry-etching by using a photoresist film 4 as a mask to form a recess, the photoresist film 4 is removed. Then a silicon nitride film 5 is built up and a photoresist film 4A is formed again. After the silicon nitride film 5 is etched together with the photoresist film 4A to leave the silicon nitride film 5 in the recess above an element forming region only, the polycrystalline silicon film 3 is removed by a wet-etching method. By subjecting a semiconductor substrate 1 in this state, the further thicker silicon oxide film 2 for element isolation is formed. With this constitution, a thermal oxidation time after the growth of the silicon nitride film can be reduced and bird's beaks can be suppressed significantly.

Title: Magnetic recording and reproducing device
Inventor: KITANO MASUO
IPC: G11B15/087
Filed: 1984-12-18
Abstract: PURPOSE:To detect whether an FM-modulated signal is recorded on a magnetic tape or not at a high speed by allowing a fixed magnetic head to detect the envelope of the FM-modulated signal recorded on a magnetic tape by a rotary magnetic head. CONSTITUTION:When a program for program search starts, a CPU34 sends a drive control signal 38 to a motor driving circuit 35 for rotating a reel motor 36. This circuit 35 flows a driving current to the motor 36 to rotate the motor 36. This motor 36 is rotated to feed the tape fast and when the tape passes on a head 16 at a high speed, the signal S1 of the head 16 is supplied to a detecting circuit 33 to detect whether there is an envelope or not. Its detection signal is sent to a CPU34, which judges whether there is the envelope or not. Consequently, if there is the envelope, the program advances to the stop of the reel motor and the CPU34 outputs a command for stopping the motor driving.

Title: Method for examining trace contaminated state
Inventor: FUJIE NOBUO
IPC: G01N21/88
Filed: 1994-10-31
Abstract: PURPOSE: To examine a contamination with a high sensitivity by arranging a silicon substrate in a space to be examined, allowing it to stand for a fixed period, exposing the surface to water, and detecting the particles adhered to the surface. CONSTITUTION: A beaker 2 containing a contaminant 5 is arranged in a vessel 1, and a bare silicon wafer 3 is arranged with the polished surface toward the material 5. The vessel 1 is allowed to stand for about 18 days after sealed by a lid 4, and the particles on the wafer surface are counted in the state where the wafer is taken out from the vessel 1, the state after it is rinsed with pure water, and the state after it is brush-scrubbed, respectively. The wafer is once taken out, for example, on the first, third, and seventh days after it is left, and returned into the vessel 1 after particle counting. Depending on the kind of the material 5, throughout these measurements, there are cases where the particles are increased but cart be removed pure water rinsing, and cases where the particles are never increased in the left state out increased after brush scrubbing.  Thus the contaminated state of the environment in which the wafer is left can be known by counting these particles.
