Title: Manufacture of semiconductor device
Inventor: MATSUMOTO JUNKO
IPC: H01L21/60
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent an unstable operation from being caused in a device due to a short-circuit between wirings and a contact. SOLUTION: This method forms an etching stopper film 20, which consists of a siliocn nitride film, on an insulating film, which protects wirings and consists of a silicon oxide film, to prevent the wirings from being damaged due to an anisotropic dry etching for opening a contact hole and forms a resist pattern having the shape of the contact hole utilizing an antireflection film, which contains nitrogen atoms. The film 20, which is located in a contact hole formation region, and the antireflection film, either of which contains nitrogen atoms and has an equal selection ratio under a prescribed condition, are simulataneously etched away. Thereby, it becomes possible to obtain a semiconductor device, which has a stable performance and can simplify the manufacturing process of the device.

Title: Manufacture of piezoelectric ceramics
Inventor: KANEKO KAZUHIDE
IPC: H01L41/257
Filed: 1989-11-08
Abstract: PURPOSE:To facilitate suppression of displacement hysteresis by a method wherein a piezoelectric ceramic element is cooled down from a temperature higher than a Curie point while a high electric field is applied to the element. CONSTITUTION:In a polarization process, a piezoelectric element is heated to a temperature higher than a Curie point and then cooled down to a temperature lower than a Curie point at the highest, or, more preferably, to a room temperature while a high electric field is applied to the element. In other words, if the piezoelectric element is heated to a temperature higher than a Curie point to make polarization regions disappear completely and then cooled down while the high voltage is applied to it, only a 180 degrees polarization region is created and a 90 degrees polarization region which causes displacement hysteresis is made to disappear. With this constitution, the displacement hysteresis can easily be eliminated.
