Title: Self-aligned diffused source vertical transistors with stack capacitors in a 4f-square memory cell array
Inventor: KALTER HOWARD LEO
IPC: H01L27/115
Filed: 1997-09-25
Granted: 2000-03-11
Abstract: A densely packed array of vertical semiconductor devices, having pillars with stack capacitors thereon, and methods of making thereof are disclosed. The pillars act as transistor channels, and are formed between upper and lower doped regions. The lower doped regions are self-aligned and are located below the pillars. The array has columns of bitlines and rows of wordlines. The lower doped regions of adjacent bitlines may be isolated from each other without increasing the cell size and allowing a minimum area of approximately 4F2 to be maintained. The array is suitable for Gbit DRAM applications because the stack capacitors do not increase array area. The array may have an open bitline, a folded, or an open/folded architecture with dual wordlines, where two transistors are formed on top of each other in each trench. The lower regions may be initially implanted. Alternatively, the lower regions may be diffused below the pillars after forming thereof. In this case, the lower region diffusion may be controlled either to form floating pillars isolated from the underlying substrate, or to maintain contact between the pillars and the substrate.

Title: Driving voltage generating device of liquid crystal display device
Inventor: KAKUTA RYOHEI
IPC: G02F1/133
Filed: 1998-06-02
Granted: 2001-07-01
Abstract: The subject of the present invention is to provide a driving voltage generating device (of a liquid crystal display device) which is small-sized and inexpensive and has its output voltage adjusted with ease. The solution of the present invention is to have a DC-DC converter 1 which boosts an input voltage (5 V) to generate a voltage VH and a voltage VL. Resistors R1 to R6 divide the potential difference between the voltages VH and VL. Operational amplifiers IC1 and IC2 output the respective resistance-divided voltages after current amplification. The DC-DC converter 1 needs to have only two output terminals, so the outward appearance can be made small and the cost can be reduced. Further, the resistances R1 to R6 are provided outside the DC-DC converter 1 (hybrid IC), so the resistances R1 to R6 can easily be replaced. Therefore, voltage VHCOM, VHSEG, VM, VLSEG, and VLCOM can easily be adjusted.

Title: Carrier for cleaning silicon wafers
Inventor: IWAMOTO YOSHIO
IPC: H01L21/304
Filed: 1999-12-07
Granted: 2003-10-21
Abstract: A carrier for receiving and holding a plurality of semiconductor wafers and permitting surfaces of the wafers to receive maximum exposure to ultrasonic waves during a wafer cleaning process in which the carrier and the wafers are immersed in a liquid medium and ultrasonic waves are generated in the liquid medium. The carrier includes spaced apart sidewalls and horizontal rods that interconnect the sidewalls and that are collectively positioned for supporting wafers in generally upright, face to face position generally parallel to each other. The rods are positioned in spaced relationship relative to each other so that wafers are exposed to the liquid medium and ultrasonic waves between the rods. The sidewalls are sized to have a maximum height that is less than about half of a wafer diameter. The carrier is adapted to hold wafers to permit generally unobstructed passage of ultrasonic waves through the liquid medium to reach all portions of wafer surfaces with minimal impedance by structure of the carrier, thereby facilitating effective cleaning. A stabilizing rod extends horizontally between central areas of the sidewalls for limiting wafer motion relative to the carrier to steady the wafers.

Title: Improved image sensing module for producing digital images having reduced noise
Inventor: LIU DONGTAI
IPC: G06K9/40
Filed: 1999-10-19
Granted: 2001-12-01
Abstract: According to one aspect of the disclosed system, an image sensing module comprises an image sensor producing an analog video signal. A nonlinear amplifier employs a nonlinear transfer function derived preferably from sensitivity characteristics in the human vision system. Upon receiving the analog video signal from the image sensor, the nonlinear amplifier produces a distorted analog video signal from the analog video signal in accordance with the nonlinear transfer function. The distorted analog video signal is then processed in the auxiliary circuits for following digitization. An analog-to-digital converter digitizes the distorted analog video signal to produce a digitized signal of the distorted analog video signal. The digitized signal of the distorted analog video signal is then preferably corrected in an image processing system, with respect to a transfer function derived from the reversal of the nonlinear transfer function used in the nonlinear amplifier, to produce a digital signal substantially close to a digital representation of the original analog video signal. As a result, noises in the digital signal are much less visible.

Abstract: A two-step process for the production of polyamides from Α, ω-dinitriles and Α, ω-diamines involving the catalytic hydrolysis of the Α, ω-dinitrile by addition of water with simultaneous purging of the reactor (i.e., venting of ammonia and water vapor) in the first step followed by polymerization by addition of the Α, ω-diamine to the hydrolysate in the second step.
