摘要:
A method of fabricating a thin film transistor substrate includes: forming a polymer layer on a glass substrate; forming a passivation layer on the polymer layer; forming a thin film transistor array on the passivation layer; and separating the glass substrate from the polymer layer by irradiating a laser from a rear surface of the glass substrate.

摘要:
The present invention relates to a method for fabricating a conductive particle, the method comprising steps of: (a) preparing a particle based on a macromolecular resin; (b) forming a layer of a nano powder on a surface of the particle; and (c) subjecting the layer of the nano powder to an electroless plating. In accordance with the present invention, a nano powder is bonded on a particle based on a macromolecular resin and an electroless conductive layer is plated such that a pretreatment process of a plating process for forming a conductive particle is omitted and the plating process is simplified from twice to once, thereby reducing a toxic substance generated in a conventional process to improve a stability of the process and reduce a manufacturing cost.
摘要:
A process for stereoselective preparation of (E)-enolthioether derivatives comprising the steps of;(a) protecting free secondary hydroxy group of L-threonine with trialkylsilyl group; (b) the protected L-threonine derivatives (I) being degraded by ninhydrin to prepare (2R)-2-(trialkylsilyloxy)propanal (II); and (c) carting out the Honor-Wordsworth-Emons (HWE) reaction of the resultant compound (II) with stabilized phosphonate ylide, phosphonium ylide or phosphine oxide ylide which was obtained by treating the organic phosphine compound (III) with strong base to provide (E)-enolthioether derivatives (IV) is provided.The present invention has advantages in comparison with the prior art in that the costs required for the process can be lowered because L-threonine, an .alpha.-amino acid of low in price is used as a starting material and the process is simple; and the desired (E)-enolthioether derivatives can be prepared with high stereoselectivity.
