摘要： A polymer that when used with a suitable photoacid generator (PAG) forms a positive working photoresist. The polymer comprises of a tartaric polyanhydride backbone, an acetal protected 1,2 diol group; and a fused ring acetal group pendant to the backbone. The acetal protected .alpha.-hydroxy anhydride backbone structure, undergoes an efficient photoacid catalyzed cleavage, which gives rise to small molecular weight fragments which are readily dissolved in an aqueous base developer. This high contrast in solubility allows high resolution images to be produced. The fused rings offer etch resistance and can be comprised of either an adamantone or norcamphor ring structure. With the addition of a commercially available photo acid generator, the polymer formulation forms a positive working photoresist that offers high contrast and resolution.

摘要： A water soluble polymer that when used with a suitable photoacid generator (PAG) forms a negative working water soluble photoresist. The polymer comprises of a backbone, such as polyvinyl ether, coupled by a linkage group to an acetal protected .beta.-keto acid group. With the addition of a number of commercially available photo acid generators, the polymer formulation forms a negative working photoresist that is water soluble. Exposure to radiation will cause a photoacid catalyzed deprotection of the acetal group, yielding a .beta.-keto acid which, upon heating, will undergo decarboxylation, which results in a water insoluble photoproduct and evolution of CO.sub.2 as a byproduct. This photochemically induced reaction results in a significant change in the polymer solubility parameter, and the product is no longer soluble in water. As this solubility change does not require crosslinking, there will be no swelling of the resist images on exposure to the aqueous base during development, and hence no loss of resolution. This enables the photoresist to be used at fine resolutions at i-line and deep UV wavelengths.
摘要翻译：当与合适的光酸产生剂（PAG）一起使用时，水溶性聚合物形成负性工业水溶性光致抗蚀剂。聚合物包括主链，例如聚乙烯醚，通过连接基团与缩醛保护的β-酮酸基团偶联。通过添加许多市售的光酸产生剂，聚合物配方形成水溶性的负性光致抗蚀剂。暴露于辐射将导致缩醛基的光酸催化脱保护，产生β-酮酸，其在加热时将经历脱羧，这导致水不溶性光产物和作为副产物的CO 2的释放。这种光化学诱导反应导致聚合物溶解度参数的显着变化，并且产物不再溶于水。由于该溶解度变化不需要交联，因此在显影期间暴露于碱性水溶液时，抗蚀剂图像不会溶胀，因此没有分辨率的损失。这使得光致抗蚀剂可以在i线和深紫外波长处以高分辨率使用。

摘要： A three-dimensional electro-optic waveguide is formed as a channel in a structure made of an organic non-linear optical polymer. A poling electric field is maintained in a portion of the polymer structure defining the channel, and the polymer structure is heated above the glass-transition temperature to enable dipolar moieties of the polymer to become aligned by the poling field. Heating continues until the dipolar moieties are sufficiently aligned to produce a higher index of refraction in the channel portion than in adjacent cladding portions of the polymer structure for at least one polarization of optical radiation propagating through the channel. The poling field is maintained as the polymer structure is then cooled below glass-transition temperature, thereby preserving alignment of the dipolar moieties (and hence preserving the differential index of refraction) in the channel portion of the polymer structure. Guided modes of optical radiation of at least one polarization can be supported in the channel.
