A suction area is located at a distal end of the collet. A pick and place collet contact area is located adjacent to and outwardly from the suction area, and comprises tapered sidewalls that depend downwardly and outwardly away from the outer periphery of the suction area. The tapered sidewalls and the outer periphery of the suction area are configured and dimensioned to cause an electronic device to substantially self-align and center itself with respect to the collet when engaged thereby.

Abstract: A memory configuration circuit is provided. The memory configuration circuit may be integrated into a programmable logic device (PLD) and as such, may be used to configure and reconfigure specific elements in the PLD. The memory configuration circuit includes a comparator circuit and a counter. The comparator circuit is coupled to receive two data words from two different memory configuration sources. The comparator circuit compares the two data words received before writing one of the data words to a configuration memory. One of the data words may be written to the configuration memory if the two data words compared are not equal. The counter increments the address of the memory configuration sources so that a next data word can be processed after the current data word is processed.

Abstract: Apparatus is disclosed for steering a directional audio beam that is self-demodulated from an ultrasound carrier. The apparatus includes means for modulating a carrier signal with an audio signal and means for adjusting the amplitude and phase of at least one of the audio signal and/or the carrier signal to steer the audio beam to a desired direction. The apparatus also includes means for generating an ultrasound beam in the desired direction driven by the modulated carrier signal. The apparatus may include means for weighting the audio and/or carrier signal by a zeroth order Bessel function to synthesize a Bessel distribution source. A corresponding method for steering a directional audio beam is also disclosed. A harmonic generator may be used to generate harmonics of low frequencies in the audio signal. The harmonics may provide (upon demodulation) a psycho-acoustic impression of improved perception of low frequencies.

Abstract: A embodiment method for forming a layout for a phase shift mask. A embodiment comprises providing a layout comprising a first feature, a first shifter region and a second shifter region. The first feature preferably has a L-shape portion with an elbow region. The first shifter region is on the outside of the L-shaped portion and the second shifter region is on the inside of the L-shaped portion. The elbow region has an outside corner away from the second shifter region. We identify a phase conflict region caused by the L-shaped portion of the first feature, the first shifter region and the second shifter region. We resolve the phase conflict by modifying the elbow region by moving the outside corner of the elbow region away from the first shifter region and the phase conflict region. The modification of the elbow region further comprises forming a jog region in the line end section of the first feature.

Abstract: A method for forming a contact hole unit cell is provided. A light transparent contact hole region of a first phase is positioned at a first plane. A light transparent phase-shifting region of a second phase is positioned at the first plane, the second phase being substantially out of phase with the first phase. The phase-shifting region substantially surrounds the contact hole region. A light transparent border region is positioned at the first plane outside and substantially surrounding the phase-shifting region. The border region has a phase substantially the same as that of the contact hole region. The contact hole region, the phase-shifting region, and the border region are positioned to cause light from the first plane to be reinforcing in a target contact hole configuration on a second plane and to be substantially neutralizing outside the target contact hole configuration on the second plane.

Further, positioning a non-transparent region at the first plane to assure radiation at the second plane to be neutralized in the first region and positioning a third radiation transparent region of the first or second phase at the first plane to neutralize the side lobes in the third region at the second plane.

Abstract: A reticle structure and a method of forming a photoresist profile on a substrate using the reticle having a multi-level profile. The reticle comprises (1) a transparent substrate, (2) a partially transmitting 180 degree phase shift film overlying predetermined areas of the transparent substrate to transmit approximately 20 to 70% of incident light, and (3) an opaque film overlying the predetermined areas of the partially transmitting 180 degree phase shift film. The method comprises the following steps: a) depositing a photoresist film over the substrate; b) directing light to the photoresist film through the reticle, and c) developing the photoresist film to form an opening in the resist layer where light only passed thru the substrate, and to remove intermediate thickness of the photoresist film, in the areas where the light passed through the partially transmitting 180 degree phase shift film. In an aspect, the photoresist film is comprised of a lower photoresist layer and an upper photoresist layer.
