Title: Maleimide monomer, its (co)polymer and resin composition
Inventor: AMO SATORU
IPC: H01L21/027
Filed: 1994-09-05
Abstract: PURPOSE: To provide a maleimide monomer suitable for a photosensitive resin composition of a chemical amplification system having high sensitivity as well as heat-resistance. CONSTITUTION: This maleimide monomer is expressed by formula (R<1> is a protective group substituting with hydrogen by an acid catalyst). The compound can be produced by protecting the hydroxyl group of hydroxyphenylmaleimide with a functional group eliminable by an acid catalyst. Preferable protective groups are t-butoxycarbonyl group and tetrahydropyranyl group. A high- sensitivity photo-sensitive resin composition imparted with high-sensitivity chemical amplification-type photosensitive mechanism and giving a heat-resistant relief pattern can be produced by adding a photo-acid generator (preferably an onium salt) to the maleimide monomer and its (co)polymer.  The resin composition may be incorporated with either one of polyhydroxyphenylmaleimide, polyhydroxystyrene, novolak resin, epoxy resin and polyimide precursor to control the solubility, heat-resistance, film-forming property, etc., of the composition.

Abstract: PURPOSE:To prevent gravel or dust from going into or rainwater from staying in a jointed portion between a rim and a disc by finish-cutting the outer surface of a wheel to remove beads and finishing the outer surface of a wheel cross section into a smooth and continuous shape. CONSTITUTION:After a jointed portion between the top edge of a flange 21 and the inner circumference of a rim 1 and a jointed portion between an arc- shaped portion made at the base edge of the flange 21 and the rim 1 are welded, weld beads 31, 32 are generated respectively on both sides of the peripheral edge of a disc 2.

Title: Ultraviolet ray resist exposing method
Inventor: TAKIZAWA MASAAKI
IPC: G03F7/20
Filed: 1989-08-18
Abstract: PURPOSE:To position the side face of a developed resist film vertical to the base layer by a method wherein a pattern exposing operation is conducted using ultraviolet rays, and also an overall exposing operation is conducted using an electron beam. CONSTITUTION:After the surface of the base layer 1 is coated with a resist film 2, a prebaking treatment is conducted thereon. The resist film 2 is exposed by a Deep UV light through an exposing mask 3. The part 4 shown in the diagram is the light- transmitting part of the mask 3, and the resist film 2 is photo-decomposed by the Deep UV light passed through the part 4. As the resist film 2 has the tendency that the distribution of absorption energy in depthwide direction becomes weaker as going deeper, the area of the photo-decomposition part 5 of the resist film 2 becomes narrower as going deeper. The distribution in depthwide direction of the absorption energy, in the case where an electron beam is projected, has the tendency of becoming stronger as going deeper, and this tendency is reverse to the case where pattern exposure is conducted using ultraviolet rays. At that point, when an overall exposure is conducted by the electron beam accelerated to 20keV or thereabout, for example, the photo-decomposition part 5 of the resist film 2 is positioned almost vertical to the surface of the base layer with uninclined side face, not in an inverted taper form.

Abstract: PURPOSE:To demodulate a data without being affected by noises even at a weak electric field by using a couple of changeover means so as to select a limiter output continuously, FM-demodulating the data and extracting a data signal.
