A method of forming a semiconductor structure comprises forming pools of acidic or basic material in a substrate structure. A resist is formed over the pools of acidic or basic material and the substrate structure. The acidic or basic material is diffused from the pools into portions of the resist proximal to the pools more than into portions of the resist distal to the pools. Then, the resist is exposed to a developer to remove a greater amount of the resist portions proximal to the pools compared to the resist portions distal to the pools to form openings in the resist. The openings have wider portions proximal to the substrate structure and narrower portions distal to the substrate structure. The method may further comprise forming features in the openings of the resist.

The invention discloses a preparation method of monoethanol diisopropanolamine. The monoethanol diisopropanolamine is prepared by mixing and reacting diisopropanolamine and epoxyethane in a reaction kettle. The method does not adopt the traditional synthesis reaction of liquid ammonia with epoxyethane and epoxypropane, but creatively reacts the raw material diisopropanolamine with epoxyethane to obtain the product. The invention has the advantages of high yield, short reaction time, mild reaction conditions and controllable process; one active position on the ammonia molecule is substituted by epoxyethane, so that the molecular structure of the product can be controlled more easily; and by using the high-content diisopropanolamine as the raw material, the product has better smell, color and reaction time than that of an ammonia process.

PROCESSES FOR PRODUCING ARYL CARBAMATES, ISOCYNATES AND POLYUREAS USING DIARYL CARBONATE

Номер: US20130079542A1
Автор: Chen Xue-Yong, Dai Shenghong A., HUANG CHUN-YING, Lin Chao-Hsing, Pan Wen-Chen
Принадлежит:

A preparation of aryl carbamates can be achieved readily by carbonylation of an aromatic polyamine compound with diphenyl carbonate (DPC) using a combination of an organic acid and a tertiary amine as a catalyst. Aryl carbamate can be converted into 4,4′-diphenylmethane diisocyanate (MDI) by heating it at about 200 to about 230° C. in a non-polar solvent containing inhibitor such as benzoyl chloride. In another application, trans-ureation of biscarbamates with an amine or mixed amines is found to be extremely facile in a polar solvent such as dimethyl sulfoxide (DMSO) and tetramethylene sulfone (TMS) in absence of any catalyst to make polyurea polymers of high molecular weights. Thus, efficient green-chemistry processes based on biscarbamates in making isocyanate products as well as urea prepolymers, urea elastomers and urea plastics have been developed in all in excellent yields without using reactive phosgene or 4,4′-diphenylmethane diisocyanate separately in the trans-ureation polymerizations. 1.

The features have wider portions proximal to the substrate structure and narrower portions distal to the substrate structure. 1. A method of forming a semiconductor structure , comprising:forming recesses in a substrate structure;filling the recesses with a pool material comprising an acid-generating material or a base-generating material;forming a resist over the pool material and the substrate structure;exposing the resist to an energy source to generate an acid or a base from the pool material, the generated acid or base diffusing into adjacent portions of the resist; andremoving a greater amount of the portions of the resist proximal to the substrate structure than the amount of the portions of the resist distal to the substrate structure to form openings in the resist, the openings comprising wider portions proximal to the substrate structure and narrower portions distal to the substrate structure.2. The method of claim 1 , wherein the substrate structure comprises a substrate and a hardmask overlying the substrate claim 1 , and wherein forming recesses in a substrate structure comprises forming the recesses extending at least partially into a thickness of the hardmask.3. The method of claim ...
