Title: Formation method of resist pattern
Inventor: TANAKA TOSHIHIKO
IPC: H01L21/027
Filed: 1992-05-13
Abstract: PURPOSE:To effectively prevent resist patterns from falling by a method wherein, when the resist patterns are formed, especially when dense and fine resist patterns or high-aspect resist patterns are former, a rinsing liquid is set to a critical state and allowed to evaporate in a state that its surface tension is zero. CONSTITUTION:In a rinsing process in the developing operation of a resist pattern, a rinsing liquid 5 which is collected between adjacent resist patterns 2a, 2b when the rinsing liquid 5 is dried is set to a state that its surface is hollow. Then, since the face of the liquid is hollow, a pressure generated at the inside is a negative pressure, and an attractive force acts between the resist patterns 2a, 2b corresponding to wall surfaces. Then, the rinsing liquid is evaporated in the critical state of the rinsing liquid, the surface tension is eliminated and the attractive force between the resist patterns 2a, 2b is eliminated. Thereby, it is possible to effectively prevent the resist patterns from falling when the resist patterns or high-aspect resist patterns are formed, and it is possible to manufacture a product whose yield is high.

Title: Dynamic ram
Inventor: KIKUTA SHIGERU
IPC: G11C11/404
Filed: 1987-06-11
Abstract: PURPOSE:To prevent latch up by connecting a storage gate electrode to ground only for a prescribed period just after application of power supply so as to reduce power consumption thereby suppressing remarkably the rise in a base voltage just after the application of power voltage while keeping high circuit integration. CONSTITUTION:A period connecting a storage gate electrode 2 to ground is set by a waveform of a power-on reset signal V. Then the period is selected to a time or over when the power voltage VCC is made stable and a negative voltage V1 is supplied stably. Then the increase in the base voltage VBB after that is suppressed by the negative voltage V1 applied from a base voltage generating circuit similarly to a conventional circuit. Thus, just after the application of the power voltage VCC, the increase in the base voltage VBB is suppressed by the transfer of the electric charge into a capacitor C3 of the memory cell 1. Thus, even just after the application of the power voltage VCC, the remarkable increase in the base voltage VBB is suppressed to prevent generation of latch up.
