Inventor: MAYDAN DAN
IPC: H01L21/768
Filed: 1989-12-15
Abstract: An improved planarization process is disclosed which comprises depositing over a patterned integrated circuit structure (2) on a semiconductor wafer (10) a conformal insulation layer (20) by ECR plasma deposition of an insulation materia. The ECR plasma deposition is carried out until the trenches or low regions between adjacent raised portions of the structure are completely filled with insulation material. A planarization layer (30) of a low melting glass material, such as a boron oxide glass, is then formed over the integrated circuit structure (2) to a depth or thickness sufficient to cover the highest portions of the ECR plasma deposited insulation layer (20). This planarization layer (30) is then anisotropically etched back sufficiently to provide a planarized surface on the ECR plasma deposited insulation layer. A further layer (40) of insulation material may then be conventionally CVD deposited over the planarized ECR plasma deposited insulation layer (30) which acts to encapsulate any remaining portions of the planarizing layer (30).

Abstract: A bowling center system (10) includes a plurality of lane pair control systems (16) each including a pinsetting device (14) for each lane (12), a pinsetter control unit, a game control unit, a bowler input station (18) and a pair of overhead display moni­tors (20R, 20L). The game control unit (16) is operable under the control of a game control program stored in a memory for automati­cally operating the pinsetter control units during game play to selectively set a sequence of pin patterns on the lane (12), which patterns may comprise any array of pins. The game control unit (16) responsive to pin fall data received from the gamesetter generates scoring information which is displayed using video graphic displays on the overhead monitors (20R, 20L). The game control program can be any one of a plurality of dif­ferent game programs which may be downloaded to the memory from a memory associated with the manager's control termi­nal. According to the particular game program, the number of bowling frames the game may vary as well as the number of balls and pins utilized in each frame. The manager's con­trol system (26) provides accounting control over the bowling center system (10) and is operable to override operation of a selected game control unit as necessary. A plurality of remote terminals (21) are provided asscciated with selected ones of said lane pair control systems (16). Each remote terminal system includes a keyboard (24) and a display monitor (22). The re­mote terminal (21) operates under the control of the game control unit (16) to allow a user thereof to enter requests for video displays. The video displays include, for example, ball trajectory displays which illustrate the path of the ball on the bowling lane, or dynamic displays, such as for training, generated by video source devices associated with the manag­er's control system (26).

Abstract: A portable light weight completely self-contained emergency single patient ventilator/resuscitating apparatus (10) usable at the scene of an emergency by persons with minimal training. The appara­tus (10) includes a housing assembly (12) which supports a solid state oxygen generator which also acts as a power supply, the gen­erator being in the form of a chlorate candle (20). The housing additionally supports a pump (90) in the form of a venturi ejector, a two-position valve (92), and suitable primary controls (93) which are utilized to control the inspiratory:expiratory (I:E) ratio, the inspiratory time, the expiratory time, the breaths per minute, the flow rate, the tidal volume, the minute volume, etc. Various fluid passageways (54, 58, 116, 118) interconnect the candle with the valve, and additional fluid lines (120, 138, 140, 146, 148) inter­connect the valve with the pump and primary controls. The primary controls include a fixed volume timing chamber (132) which is dis­posed about the venturi ejector. The housing is provided with a void (98) adjacent the timing chamber, which void acts as an accumu­lator during the expiratory cycle. While the two-position valve is normally automatically switched between inspiratory and expiratory positions by the primary control, it may be manually switched from its expiratory position to its inspiratory position against full pilot line pressure by a secondary control including a push button (152) or the like when the operator desire to give extra breaths or sigh breaths. In addition, the push button can be so positioned that the valve may be maintained in its inspiratory position, which may be desirable when the patient is breathing on his own and only requires extra oxygen over that which he would normally receive from ambient air.

In one embodi­ment of the present invention, a slider configuration includes a first air bearing region (31) at the leading edge of the slider and a second air bearing region (32) at the slider's trailing edge. The first air bearing region includes a tapered region (37). A deformable central region (33), including a non air bearing surface, joins the first and second air bearing regions and controls the relative angle between the air bearing surfaces. The relative angle is adjusted by deforming the central region using a layer of e.g. piezoelectric material which overlays the central region. A conventional read/write head is placed on the rear portion of the second air bearing region.

Abstract: A method is provided for assessing the generalized genetic change which occurs during tumorigenesis. The method relies on measurement of loss of a large number of alleles from the chromo­somes of the tumor cells. The alleles are RFLP markers. The role of any of the particular alleles in tumorigenesis need not be known. The amount of allelic loss allows a prognosis to be made regarding tumor metastasis, tumor recurrence, and mortality.
