Abstract: A grill pan includes a flat portion and two slanting portions. The slanting portions are connected to each side of the flat portion respectively. Each of the slanting portions is formed with a spout positioned opposite to where the flat portion and the slanting portion meet. The slanting portions are slightly higher than the flat portion to divide a cooking area for low-fat food and a cooking area for high-fat food, and the slanting portions slope downward from the flat portion to allow any fluid on the cooking area for high-fat food to flow toward the spout instead of the cooking area for low-fat food during cooking.

Abstract: A method of forming a gate insulator in the manufacture of a semiconductor device comprises conducting a photo-assisted electrochemical process to form a gate-insulating layer on a gallium nitride layer of the semiconductor device, wherein the gate-insulating layer includes gallium oxynitride and gallium oxide, and performing a rapid thermal annealing process. The photo-assisted electrochemical process uses an electrolyte bath including buffered CH3COOH at a pH between about 5.5 and 7.5. The rapid thermal annealing process is conducted in O2 environment at a temperature between about 500° C. and 800° C.

Abstract: A method and apparatus are described for removing an initial gas from a gas-filled enclosure between the mask-protective device, such as a pellicle, and the patterned mask, such as a reticle, and adding a purge gas with a different composition. The gas-filled enclosure includes a vent for adding the purge gas to the chamber and removing the initial gas from the chamber. Adding and removing may be accomplished by using pressure, diffusion, vacuum, or other means.

Abstract: A method for manufacturing gallium nitride based transparent conductive oxidized film ohmic electrodes includes forming a transparent conductive film on a GaN layer, forming a transparent conductive hetero-junction of opposing electrical characteristics on a transparent conductive film on the surface of the GaN layer through an ion diffusion process, and laying a metallic thick film on the surface of the transparent conductive hetero-junction for wiring process in the later fabrication operation. Thus through the electron and hole tunneling effect in the ion diffusion process the Fermi level of the hetero-junction may be improved to form an ohmic contact electrode.

Abstract: Plasma etching is controlled utilizing two etchant gases to form a plasma so as to obtain controlled (e.g., uniform) etch rate across a wafer. One etchant gas forms appositive plasma, which is the dominant plasma. The other etchant gas forms a negative plasma, which is the secondary plasma. The ratio of dominant plasma to the secondary plasma can be adjusted such that ion densities are uniform across the wafer, resulting in uniform etch rate over the wafer.
