Title: Semiconductor device
Inventor: USHIKUBO MAHO
IPC: H01L21/76
Filed: 1992-07-02
Abstract: PURPOSE:To obtain a semiconductor device enabling simplification of a process, by forming an electrode on a laminated ferroelectric film. CONSTITUTION:When a voltage of -Vcc is impressed on an electrode 15 and a silicon substrate 1 is grounded, the part of a P2T film 12 covered with the electrode 15 is polarized upward and, therefore, holes are induced in the surface of the silicon substrate 1 in the part of a P region 2 between a drain region 4 and a source region 5. When a voltage of +Vcc is impressed on an electrode 16 and the silicon substrate 1 is grounded likewise, the part of the P2T film 12 covered with the electrode 16 is polarized downward and, therefore, electrons are induced in the surface of the silicon substrate 1 having no impurities between the drain region 4 and the source region 5. Accordingly, a Pn junction is formed between the drain region and the source region by the holes and the electrons and a ferroelectric film in an isolating region can be prepared simultaneously when a gate ferroelectric film of FET is prepared. Therefore a process of isolating discrete FETs can be simplified.

Title: Image forming material
Inventor: TAGUCHI TAKAO
IPC: G03F7/004
Filed: 1982-10-07
Abstract: PURPOSE:To improve a reducing effect in a photomechanical process by successively forming a light shielding layer and a photosensitive resin layer which is swellable but insoluble in a soln. for dissolving the light shielding layer and contains an extender of a specified particle size on a transparent flexible film. CONSTITUTION:A polyethylene terephthalate film having a light shielding layer of vapor-deposited Al is coated with a photosensitive liq. prepared by dispersing an extender of <=5mum particle size such as silica in a diazo type photopolymer to form a photosensitive layer having moderate unevenness on the whole surface of the light shielding layer. The resulting photoreceptor is exposed and developed. By the development the exposed part of the photosensitive layer is removed, and at the same time, the Al layer is etched to obtain a positive image. When the image is reduced with a reducing soln., the contact area is increased because the resin layer has unevenness due to particles of <=5mum particle size over the whole film, and the resin layer is well permeable to the reducing soln., so the reduction can be carried out in a short time even if the resin layer is perfectly cured.
