摘要:
A method of forming a polymer film on a surface of a substrate is described. The method comprises placing a substrate on a substrate holder in a vapor deposition system, and introducing a process gas to the vapor deposition system, wherein the process gas comprises a monomer, a cross-linking monomer, and an initiator. Thereafter, the substrate is exposed to the process gas in order to form a polymer film on the substrate, wherein the polymer film thermally decomposes at a decomposition temperature.

A method includes performing a dicing on a composite wafer including a plurality of dies, wherein the composite wafer is bonded on a carrier when the step of dicing is performed. After the step of dicing, the composite wafer is mounted onto a tape. The carrier is then de-bonded from the composite wafer and the first tape.

A wafer level package includes a semiconductor die bonded on a supporting wafer. The semiconductor die has at least a step recess at its substrate. An underfill layer is formed between the semiconductor die and the supporting wafer. Moreover, the height of the underfill layer is limited by the step recess. During a fabrication process of the wafer level package, the step recess helps to reduce the stress on the wafer level package.

The present invention relates to a process for preparing an optical waveguide component from acrylate/titanium alkoxide composite material, which is characterized by using an acid-free sol-gel process to prepare a precursor solution of acrylate/titanium alkoxide composite film, then coating the precursor solution on a silicon wafer then drying, and producing the optical waveguide component having channels by using a lithography process. The present invention also relates to an optical waveguide component of acrylate/titanium alkoxide composite material, the material has excellent transparency and its refractive index varies with the amount of titanium alkoxide contained therein. When an optical waveguide component is prepared from the composite the reduction of near-infrared ray is less than 0.7 dB/cm and therefore the waveguide component is advantageous for use as an optical communication element.
