Abstract: A memory management system for a packet data mode system is used in conjunction with a direct memory access controller. The management system is of the type for communicating packet data into and out of memory storage. Each message in a packet data mode system contains a control address field and a data field. A change of field signal is generated and communicated to the DMA controller. An end of message signal is generated and communicated to the DMA controller. The control address field is stored separately from the data field. This increases the efficiency of the data storage and enhances the density of information packing into the memory storage.

Abstract: An electronics controller for controlling the power supply of a laser operating in a pulse mode is disclosed. The power supply is of the type having a resonant DC converter, charging a capacitive storage means with an inverter stage driving the laser discharge tube.

Set points for the current, the voltage, and on/off are provided to the electronics controller as the comparison points for the controller. Based upon the voltage and current detected, and the set points provided, the controller controls the on/off of the converter and its frequency, and the on/off of the inverter.

Abstract: A methd of making an electrically programmable and erasable memory device having a re-crystallized floating gate is disclosed. A substrate is first defined. A first layer of dielectric material is grown over the substrate. A layer of polysilicon or amorphous silicon is then deposited over the first layer. The layer of silicon is covered with a protective material and is annealed to form recrystallized silicon. A portion of the protective material is removed to define a floating gate region. Making oxide is grown on the floating gate region. The remainder of the protective material and the recrystallized silicon thereunder is removed. A second layer of dielectric material is formed over the floating gate and over the substrate, immediately adjacent to the floating gate. A control gate is patterned and formed. Source and drain regions are then defined in the substrate.

Abstract: A semiconductor wafer processing apparatus has a processing housing including a pair of coaxial hollow cylindrical members each defining an inner cylindrical chamber for directing a treatment medium toward a wafer and an annular chamber for withdrawing the treatment medium. A wafer support which can include a heater holds one or two wafers substantially normal to the axis of the processing housing. The treatment medium is introduced in vapor phase at very low to high velocity and at subatmospheric to superatmospheric pressure. Radiation can be introduced into the housing, and wafers can be automatically moved into and out of the housing and from the housing to another treating apparatus.

Abstract: A VTR incorporating a video printing controller comprising at least one rotary magnetic head for scanning recording tracks formed on a magnetic tape to reproduce a video signal recorded on a recording track specified by a marker signal, a marker signal detector for detecting the marker signal specifying the recording track carrying the video signal to be printed, and a system controller connected to the marker signal detector and to a video printer connected to the VTR. The system controller gives a video printer control signal to the video printer upon receipt of a marker signal detection signal from the marker signal detector to control the video printer for printing out in a hard copy the video image reproduced from the recording track specified by the marker signal. Thus, the recording track storing the video image desired to be printed is located automatically by searching the recording tracks for the marker signal, and then the desired video signal is printed out automatically.

Abstract: A method for measuring the proper exposure and registration of layers of desired circuit features on an integrated circuit wafer. The process of making the integrated circuit feature is modified in three ways. First, a structure is added to the mask pattern for each layer, apart from the desired circuit feature and parallel with and abutting the previous layer structure, comprising a plurality of geometric patterns arranged in a progressively overlapping edge-to-edge orientation on the mask pattern. The progressive overlap is such that at one end of the structure there is a substantial separation between the opposing edges of the geometric patterns, in the middle of the structure the opposing edges of the geometric patterns meet, and at the other end of the structure there is a substantial overlap of the opposing edges of the geometric patterns. The non-opposing edges of the geometric patterns are offset relative to a reference pattern in the middle of the structure.

Abstract: A method and an apparatus for detecting the endpoint in a plasma etching process is disclosed. The invention uses a positive filter and a negative filter simultaneously to generate a first and a second signal respectively. The first and second signals are combined to form a combined signal. A change in the combined signal is indicative of the endpoint.

Abstract: Apparatus and methods for encoding information characters received by a station from a transmission medium to generate internal code points for retrieval or retransmission by the station. The encoding provides an internal symbol set that is able to pass complete line state information via its internal code points, thereby eliminating the need for extra signals to indicate the current line state. The code points can also report error situations, such as elasticity buffer errors, and can be accepted by the station's transmitter to be encoded and, after appropriate filtering, repeated onto the transmission medium. The internal code points are optimized so that the code point set minimizes the decoding logic at the receiving end, be it the station's Media Access Control function or its transmitter. Furthermore, internally, the station may make use of the internal code points to synchronize the receiver elasticity buffer.

Simultaneous mixing means are provided for the lysing reagent addition step.

Abstract: A laser system is disclosed wherein a solid state gain medium (30) is longitudinally pumped with the beam (40) from another laser (42). The laser is configured with an optically stable resonator while at the same time matching the shape of the pump beam to the shape of the cavity beam in the gain medium. Optimum matching is achieved by taking into consideration thermal lens effects in the gain medium resulting from absorption of the pump beam.

Abstract: In an ellipsometric apparatus, a laser is provided for generating a probe beam. The probe beam is passed through a polarization section to give the beam a known polarization state. The probe beam is then tightly focused with a high numerical aperture lens onto the surface of the sample. The polarization state of the reflected probe beam is analyzed. In addition, the angle of incidence of one or more rays in the incident probe beam is determined based the radial position of the rays within the reflected probe beam. This approach provides enhanced spatial resolution and allows measurement over a wide spread of angles of incidence without adjusting the position of the optical components. Multiple angle of incidence measurements are greatly simplified.

Abstract: A method and an apparatus for assembling, editing and producing a production video cassette from a source video cassette without timing signal recorded thereon is disclosed. The source video cassette is initially dubbed onto a dub cassette with timing signals recorded thereon. The dub cassette is edited and assembled, using the timing signals recorded thereon. Using the sync count of the original source cassette, the timing signal of the desired video scene is correlated with the sync field count of the source video cassette. A production cassette is made from the source cassette without the timing signal. The present invention also discloses assembling, editing and viewing a video cassette having timing signals associate recorded thereon. The cassette recorder is operated on based upon the performance characteristics which were predetermined. The assembling and editing of each of the video cassettes is done to form the video production.

Abstract: A method and apparatus are disclosed for evaluating surface and subsurface features in a semiconductor sample. In operation, a periodic energy source is applied to the surface of the semiconductor sample to generate a periodic electron-hole plasma. This plasma interacts with features in the sample as it diffuses. The plasma affects the index of refraction of the sample and the changing plasma density is monitored using a radiation probe. In the preferred embodiment, the radiation probe measures the plasma induced periodic changes of reflectivity of the surface of the sample to yield information about the sample, such as ion dopant concentrations, residue deposits and defects.

Abstract: A self-aligned masking process for use with ultra-high energy implants (implant energies equal to or greater than 1 MeV) is provided. The process can be applied to an arbitrary range of implant energies. Consequently, high doses of dopant may be implanted to give high concentrations that are deeply buried. This can be coupled with the fact that amorphization of the substrate lattice is relatively localized to the region where the ultra-high energy implant has peaked to yield a procedure to form buried, localized isolation structures.
