In a design-system distributing method, when a server side design system is updated, a server compares an updated server side design system and a client update state data, and the server distributes an update assisting system, an update indication data and a difference data to a client system based on the comparing result. The client system stores the update assisting system, the update indication data and the difference data, and the client system starts the stored update assisting system such that an update notice is outputted to a user of the client system to urge update of the client side design system each time a preset condition is satisfied until an update command of the client side design system is supplied to the client system. The client system updates the client side design system based on the stored update indication data and the stored difference data in response to the update command. The client system generates and transmits the client update state data to the server to indicate an update state of the client side design system for this time, and the server updates the client update state data based on the client update state data received from the client system.
摘要:
The MFIS transistors heretofore have a problem that after data writing, the data disappear in terms of memory transistor operation in about one day at most. This is mainly because the buffer layer and the ferroelectric have a high leakage current and, hence, charge is accumulated around the interface between the ferroelectric and the buffer layer so as to shield the electric polarization memorized by the ferroelectric, making it impossible for the electric polarization of the ferroelectric to control electrical conduction between the source and the drain in the transistor. In the present invention, by constituting an insulator buffer layer 2 of HfO2+u or Hf1−xAl2xO2+x+y, the leakage current flowing through each of the insulator buffer layer 2 and a ferroelectric 3 can be reduced and a memory transistor having a truly sufficient long data holding time is realized.

摘要:
A method of forming film on a substrate, in which in a preliminary step information on film thickness deposited on a test substrate prepared for use in collecting information over a fixed irradiation time is obtained in advance while shining a laser beam on a target, there being a fixed positional relationship between spatial positions of the test substrate and an incidence point of the laser beam on the target, or while shining the laser beam on the target while rotating the test substrate. In a main step, a deposition time at each relative positional relationship is adjusted based on film-thickness distribution information obtained in the preliminary step while spatially moving or rotating the substrate or substrate holder about a specific central axis of rotation relative to the incidence point of the laser beam to the target, or while performing both the relative rotation and relative movement.
