  • Patent number: 6693938
    Abstract: A discharge circuit for pulsed laser 10 in which one connecting portion of a preionization capacitor Cpp is connected to a preionization electrode 4 and the other one connecting portion of the preionization capacitor Cpp is connected to a junction between a capacitor C2 and a magnetic switch AL2. In the discharge circuit for pulsed laser 10, a voltage Vcc of the preionization capacitor Cpp, which is charged in synchronization with the charging of the capacitor C2, increases at a time t3 earlier by a predetermined time than a start time t6 of main discharge by the main discharge electrodes 1, 2. When a voltage of the preionization electrode 4 increases to a predetermined preionization start voltage through the preionization capacitor Cpp, a main discharge gap 3 is preionized by a corona discharge caused by the preionization electrode 4 and the main discharge is caused by the main discharge electrodes 1, 2 with the main discharge gap 3 fully preionized.

  • Patent number: 6686300
    Abstract: A method of photolithographically forming an integrated circuit feature, such as a conductive structure, for example a gate electrode (15), or such as a patterned insulator feature, is disclosed. A critical dimension (CD) for a photolithography process defines a minimum line width of photoresist or other masking material that may be patterned by the process. A photomask (20, 30, 40, 50, 60) has a mask feature (25, 35, 45, 55, 65) that has varying width portions along its length. The wider portions have a width (L1) that is at or above the critical dimension of the process, while the narrower portions have a width (L2) that is below the critical dimension of the process. In the case of a patterned etch of a conductor, photoexposure and etching of conductive material using the photomask (20, 30, 40, 50, 60) defines a gate electrode (15) for a transistor (10) that has a higher drive current than a transistor having a uniform gate width at the critical dimension.
