Filed: 1988-06-17
Abstract: PURPOSE:To realize high density and high speed by counting a multilayer film consisting of a polysilicon film, an SiO2 film, and a resist film, and equalizing the etching rate between the resist film and the SiO2 film so as to form a polysilicon S/D electrode by self-alignment. CONSTITUTION:Using such etching gas that the etching rate between a resist film and an SiO2 film becomes equal, the second resist film 13 is etched back. At this time, since the upper side of a polysilicon gate electrode 24 is the highest as compared with the surrounding, the third SiO2 film 12 at this part first appears. When the etching is continued further, only the SiO2 film at this part is removed and an opening 52 opens and the second polysilicon film appears. Next, wet etching or isotropic dry etching is performed from this opening 52 so as to remove the second polysilicon film 11 by etching up to the proper position that it contacts with a side wall spacer 28 and that at least the semiconductor substrate where high concentration S/D areas 9 and 10 are formed is not exposed. After that, when the second resist film is removed, polysilicon S/D electrodes 14 and 15 are formed.

Title: Solid agricultural chemical and application thereof
Inventor: KOSUGI SOHACHI
IPC: A01N25/10
Filed: 1990-06-08
Abstract: PURPOSE:To produce a solid agricultural chemical by forming and solidifying a mixture consisting of wooden powder, agricultural chemical, water soluble paste and favorite food of insect pest in a form of gain, pellet, bullet, etc. and to lay the resultant solid agricultural chemical underground by a method boring soil and punching and sprinkling the chemical and then covering the soil. CONSTITUTION:A mixture consisting of wooden powder having <= 0.5 mm diameter, agricultural chemical (e.g. insecticide, germicide or herbicide), water soluble paste (e.g. CMC) and favorite food of insect pest (e.g. sugar or powder milk) is formed and solidified in a form of grain, pellet, bullet, etc., to produce the solid agricultural chemical. The solid agricultural chemical is convenient to handle and free from fear in which a person in charge adsorbs harmful gas or the chemical sticks to skin and is free from loss of agricultural chemical by raining or sprinkling of water, because the chemical is buried in the ground when the chemical is applied. Consequently, it is not required to use a large amount of agricultural chemical in order to compensate the loss and agricultural chemical having high concentration is not mixed into drain. The chemical increases effective term remarkably and also has soil improving effects by rot of wooden powder.

Title: Bipolar level shift circuit
Inventor: HASHIMOTO MASAMI
IPC: H03K19/0185
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To convert both positive and negative levels of a low level system into those of a high level system simultaneously by connecting a MOSFET of opposite conduction type in parallel with each MOSFET being a component of a high level system latch circuit in a complementary way. SOLUTION: MOSFETs 1-8 connected in crossing being components of a latch circuit are provided between power supply points of a high level system (between +VDD2 and -VSS2 ). Then MOSFETs 9-12 of opposite conduction type connect respectively in parallel with the MOSFETs 1, 3, 5, 7 and they are controlled in a complementary way by an input signal or its inverse signal to a low level system (between +VDD1 and -VSS1 ). Thus, in the case that the input signal to the low level system is changed, a clue to start inversion is produced and a signal of the high level system is obtained.  Furthermore, after the end of inversion, since the conduction type of the MOSFETs 9-12 connected in parallel is opposite, the MOSFETs 9-12 are completely interrupted when an off-signal is fed to each gate electrode regardless of the low level system, no leakage current flows and the circuit with low power consumption is obtained.
