摘要： An LED-based photolithographic illuminator with high collection efficiency is disclosed. The illuminator utilizes an array of LEDs, wherein each LED has an LED die and a heat sink. The LED dies are imaged onto the input end of a homogenizer rod to substantially cover the input end without inclusion of the non-light-emitting heat sink sections of the LED. A microlens array is used to image the LED dies. The collection efficiency of the illuminator is better than 50% and the illumination uniformity at the output end of the light homogenizer is within +/−2%.

摘要： Methods of annealing a thin semiconductor wafer are disclosed. The methods allow for high-temperature annealing of one side of a thin semiconductor wafer without damaging or overheating heat-sensitive electronic device features that are either on the other side of the wafer or embedded within the wafer. The annealing is performed at a temperature below the melting point of the wafer so that no significant dopant redistribution occurs during the annealing process. The methods can be applied to activating dopants or to forming ohmic contacts.

摘要： Each sensor of a linear array of sensors includes, in part, a sensing electrode and an associated feedback circuit. The sensing electrodes are adapted to be brought in proximity to a flat panel having formed thereon a multitude of pixel electrodes in order to capacitively measure the voltage of the pixel electrodes. Each feedback circuit is adapted to actively drive its associated electrode via a feedback signal so as to maintain the voltage of its associated electrode at a substantially fixed bias. Each feedback circuit may include an amplifier having a first input terminal coupled to the sensing electrode and a second input terminal coupled to receive a biasing voltage. The output signal of the amplification circuit is used to generate the feedback signal that actively drives the sensing electrode. The biasing voltage may be the ground potential.

摘要： Radiant energy line source(s) (e.g., laser diode array) and anamorphic relay receiving radiant energy therefrom and directing that energy to a substrate in a relatively uniform line image. The line image is scanned with respect to the substrate for treatment thereof. Good uniformity is provided even when the line source is uneven. Optionally, delimiting aperture(s) located in the anamorphic relay focal plane and a subsequent imaging relay are includeable to permit substrate exposure in strips with boundaries between adjacent strips within scribe lines between circuits. An anamorphic relay focal plane mask with a predetermined pattern can be used to define portions of the substrate to be treated with the substrate and mask scanning motions synchronized with each other. Control of source output, and position/speed of the substrate, with respect to the line image, allows uniform dose and required magnitude over the substrate.

摘要： A broadband diffractive lens or imaging element produces a sharp focus and/or a high resolution image with broad bandwidth illuminating radiation. The diffractive lens is sectored or segmented into regions, each of which focuses or images a distinct narrowband of radiation but all of which have a common focal length. Alternatively, a serial stack of minus filters, each with a diffraction pattern which focuses or images a distinct narrowband of radiation but all of which have a common focal length, is used. The two approaches can be combined. Multifocal broadband diffractive elements can also be formed. Thin film embodiments are described.
