摘要:
A semiconductor device including a metal-insulator-metal (MIM) capacitor is manufactured such that a via for connecting upper and lower conductive layers is formed through an insulating interlayer after a silicon nitride layer is deposited as a thick layer on the insulating interlayer. This protects an edge of a MIM structure during an etching process that forms the via. In addition, a fluorine gas can be used in a gas stripping process to remove a polymer residue when stripping the photoresist used to form the via. The MIM capacitor has an insulator layer. The method of manufacturing the device includes forming an insulator layer of the MIM capacitor to a predetermined thickness on the insulating interlayer. The predetermined thickness is equal to the desired thickness plus an augmentation thickness, and the augmentation thickness is determined according to the stripping process for removing the photoresist pattern.

A re-circulating time-to-digital converter (TDC) can include a triggered reference ring oscillator (TRRO) and a delay module. The triggered reference ring oscillator can, when triggered by a reference signal edge, generate a periodic ring oscillator signal with a ring oscillator period that is a selected ratio of a voltage-controlled oscillator (VCO) period. The delay module can store, in a plurality of latches, samples of a VCO signal docked by the periodic ring oscillator signal. Each latch can generate an output of the sample, and each latch output can represent a time difference polarity between VCO signal and TRRO signal. In another example, the re-circulating TDC can include the triggered reference ring oscillator, a digital frequency lock module, and a TDC post-process module. The digital frequency lock module can generate a ring oscillator control signal, which sets the ring oscillator period for the triggered reference ring oscillator. The TDC post-process module can generate a TDC output, which can be a binary representation of a phase difference between a reference signal and a VCO signal.

Provided is a tabletop interface system. A tabletop input device diffuses an infrared light emitted based on at least one touch input from a user. A tabletop output device allows the diffused infrared light to pass therethrough to display content information corresponding to at least one touch point. The tabletop recognition device recognizes the at least one touch point by generating a touch image data based on the infrared light passing through the tabletop output device and generates touch point information by using the touch image data. The content server transmits the content information, which corresponds to the touch point information received from the tabletop recognition device, to at least one content client application.

A method for removing mottled etch in a semiconductor fabricating process, prevents mottled etch from being generated after etching, by performing ashing using an oxide plasma, prior to performing wet etching using a photoresist pattern. The method for removing the mottled etch includes the steps of forming a gate oxide film on a semiconductor substrate; forming a photoresist pattern on the substrate; performing ashing using an oxygen plasma; and removing the oxide film consequently by wet etching, the oxide film being opened by the pattern.

Disclosed is a method and apparatus to extend TDC resolution to better than 1 ps without incurring a matching and power penalty. Higher resolution can be achieved by segmenting the resolution between a mismatch free re-circulating time-to-digital converter (RTDC) and a stochastic time-to-digital converter (STDC). The disclosed RTDC replicates the same delay element to eliminate mismatch with the required dynamic range (200 ps for a 5 GHz example) and moderate resolution (3-5 ps typical corresponding to 6-7 bits for the 5 GHz case). While the STDC can achieve a resolution of 50 fs but with a range of only 3-5 ps which also corresponds to approximately 6-7 additional bits by exploiting process variations and mismatch to achieve a very fine resolution with limited dynamic range.
