Abstract: PURPOSE:To realize a high integrity by a method wherein an aperture with a specific width is provided in a first insulating film formed on a silicon substrate and a void is formed in a second insulating film built up in the aperture and a V-trench is obtained in the silicon substrate by anisotropic etching by utilizing the void. CONSTITUTION:A silicon nitride film 2, for instance, is built up on a silicon substrate 1. After a photoresist film 3 is applied to the silicon nitride film 2 and patterned, the silicon nitride film 2 is etched by using the patterned photoresist film 3 as a mask. Then an aperture 4 with a width about 1mum is formed. After the photoresist film 3 is removed, a silicon oxide film 5, for instance, is built up on the surface including the aperture 4. Because of the inferior step coverage inside the aperture 4, a space (void) 6 is formed. Then the silicon oxide film 5 on the whole surface is etched back. At that time, the upper part of the silicon substrate 1 is successively removed together with the insulating film 5 beneath the void 6 by anisotropic etching to form a Y- trench 7 with a width less than 1mum. Thus, an element isolation layer can be formed.

Title: Method and unit for synchronous position control
Inventor: KATO HIROAKI
IPC: G05D3/00
Filed: 1995-03-02
Abstract: PURPOSE: To improve the performance of holding the synchronism of respective stages if disturbance occurs to some of the stages by putting position information on other stages in a feedback loop of each stage. CONSTITUTION: This device is provided with synchronism compensators 3a and 3b which put position information on stages 12 and 11 in feedback loops 1a and 2a, and 1b and 2b of the stages 11 and 12. In this constitution, if disturbance is applied to one stage to cause a position shift, the current position of this stage is inputted as a target value to the other stage through the synchronism compensators 3a or 3b, so the position shift is reflected on target value variation of the other stage. Namely, if one stage has delay, the target value of the other stage also decreases correspondingly and if one stage leads, the other stage also leads. Both the stages have no discrimination between a master and a slave and one stage varies so as to maintain the synchronism as the other stage shifts in position.
