Patent JP-H03120745-A (JP)
Title: Manufacture of semiconductor device
Inventor: KATO JURI
IPC: H01L21/768
Filed: 1989-10-03
Abstract: PURPOSE:To avoid abnormal electric characteristics of a transistor, bubble of a boundary by forming a spin coated insulating film, and then heat treating it at a temperature lower than the spin coated film curing temperature. CONSTITUTION:Many transistors are formed on an Si substrate 1, and separated by AL alloy interconnection 3 of a first layer and an insulating film 2. After the interconnection 3 is formed, an interlayer insulating film is formed of a CVD SiO2 film 4, flattened by a spin coated insulating film 5, and heat treated to be cured. In this case, if a barrier layer exists in the base of the interconnection 3 of the first layer, no punchthrough of an AL diffused layer occurs. If AL alloy of a second layer is formed by sputtering, the step coverage of AL interconnection 6 is improved. This heating temperature is lower than its curing temperature. After the interconnection 6 is patterned, an Si3N4 film 7 is CVD- formed to protect its surface. The CVD reaction temperature at this time is lower than the curing temperature.

IPC: G01L21/00
Filed: 1986-10-31
Abstract: PURPOSE:To measure an atmospheric pressure accurately, by measuring the atmospheric pressure depending on changes in the drag of gas molecules acting on a planar vibrator to prevent any aging in the detection value. CONSTITUTION:When a vibration voltage is applied with a vibrating circuit 7, a planar vibrator 2 vibrates. Here, the electrostatic capacitance changes between the vibrator 2 and a displacement detection electrode 6 and hence, the displacement of the vibrator 2 can be detected by checking changes in the electrostatic capacitance with a displacement phase output circuit 8. A phase difference detection circuit 9 detects a phase lag in the displacement of the vibrator 2 as a detected with the displacement detection circuit 8 with respect to the applied voltage of the vibration circuit 7. The phase lag maintains a one-to-one correspondence with an atmospheric pressure.

Title: Method and apparatus for holding substrate
Inventor: TAMURA NAOYUKI
IPC: H01L21/203
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To reduce foreign matters on the underside of a substrate, by controlling the area of contact between a wafer and a placement table by electrostatic suction to not more than 1/2 of the area of the wafer, forming at least one annular contact portion between the circumference of the wafer and the center of the wafer as well as on the circumference of the wafer, and providing portions other than the contact portion with a gap. SOLUTION: When a substrate 1 is placed on the projection 3 on a support member 2 for substrates 1, the substrate 1 is anchored to the support member 2 by the projection 3 on the support member 2 connected with an electrostatic attraction circuit. Control of the temperature of the substrate 1 is provided by cooling gas, filled in the recess 8 in the supporting member 2, taking on thermal conduction of the temperature-controlled support member 2 and the substrate 1. Further, electrostatic attraction force is generated by a dielectric 18 stuck to or formed on the surface of the support member 2.  Since the substrate 1 is in contact with the support member 2 only through the projection 3, portions of the underside of the substrate where foreign matters may stick due to contact with other members are limited to the portion of the underside of the substrate corresponding to the projection 3.

IPC: H04Q9/00
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of a reception distance by correcting the detection sensitivity of a signal detection comparator by deciding whether the level of external disturbance light noises contained in a remote control signal is high or low. SOLUTION: The output part of a control circuit 109 is connected to a transconductance amplifier A2 in an amplifier circuit 102 provided with a signal detection comparator 106 and an AGC function. The signal detection comparator 106 is composed of a differential amplifier, constant current source and current mirror, and switches the signal detection sensitivity corresponding to the level detected result of external disturbance light noises obtained by a noise level detection circuit 104. Besides, since the output current of the control circuit 109 is applied to the current mirror and the gain of the transconductance amplifier A2 is controlled, the amplitude of disturbance light noises is suppressed, sensitivity drop caused by the increase of the noise amplitude is suppressed and further, the reduction of reception distance can be improved.
