A method for fabricating a three-dimensional structure comprises the steps of: preparing a substrate; irradiating focus ion beam to a surface of the substrate and forming an etching mask including an ion containing portion in the irradiated region; and dry-etching the substrate from a diagonal direction using the etching mask and forming a plurality of holes. | 11-20-2008 |
20080290064 | METHOD FOR FORMING SAPPHIRE MICRO-LENS IN LED PROCESS - A method for forming a micro-lens on a sapphire substrate in an LED process. In the method for forming the micro-lens on the sapphire substrate in the LED process, the ratio of source power and bias power used to generate plasma into a chamber is set to the optimum ratio of 3:1 in order to minimize the burning phenomenon of a photoresist mask caused by plasma having strong potential when a conventional micro-lens is formed. In essence, plasma having low potential energy can be realized in RIE etch used to form the micro-lens on the sapphire substrate, thereby minimizing the burning phenomenon of the photoresist mask. A yield rate can be improved in the LED process. | 11-27-2008 |
20090230087 | MICROELECTRONIC IMAGERS WITH INTEGRATED OPTICAL DEVICES AND METHODS FOR MANUFACTURING SUCH MICROELECTRONIC IMAGERS - Microelectronic imagers with integrated optical devices and methods for manufacturing imagers. The imagers, for example, typically have an imaging unit including a first substrate and an image sensor on and/or in the first substrate. An embodiment of an optical device includes a stand-off having a compartment configured to contain the image sensor. The stand-off has a coefficient of thermal expansion at least substantially the same as that of the first substrate. The optical device can further include an optics element in alignment with the compartment of the stand-off. The stand-off can be formed by etching a compartment into a silicon wafer or a wafer of another material having a coefficient of thermal expansion at least substantially the same as that of the substrate upon which the image sensor is formed. The optics elements can be formed integrally with the stand-offs or separately attached to a cover supported by the stand-offs. | 09-17-2009 |
