Without any via connections, the design configuration is very simple which facilitates the crafts of fabrications. The filter achieves a center frequency of 60.275 GHz, a 3-dB bandwidth of 3.15 GHz (5.22%), and a compact size of only 1.3 × 0.74 mm2.

However, this process is often contaminated by particles, and Particle per Wafer Pass (PWP) test must be carried out to monitor the contamination. Unfortunately, in actual manufacturing, the gaseous recipes used during etching vary on the etched materials, which lead to unexpected and unpredictable byproducts and particle counts in a given production run, rendering the particle count from PWP highly stochastic which may result in missing of the time for necessary wet cleaning of the chamber. In this work, we analyze the daily PWP results from an inductively coupled plasma etching (ICP) chamber for an eight-month period. The behavior of the particle count can be modeled as a stochastic function of the accumulated gaseous recipes flowing though the chamber. The particle count is found to follow a Negative Binomial (NB) distribution with varied parameters. The model is useful in determining the optimal time for wet clean","PeriodicalId":6363,"journal":{"name":"2011 IEEE International Conference of Electron Devices and Solid-State Circuits","volume":"22 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2011-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80023592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It's fabricated with TSMC 0.35µm DDD process. The chip contains 16 channels and the maximum/minimum output current is 3mA/45mA, respectively. The value of each channel's output current is the same and controlled by a programmable 6-bits digital input signals. The circuit uses constant gate voltage of the power MOS working in the linear region whose (Vgs — Vth) is 10 to 50 times of Vds. The advantage is no DAC(Digital-to-Analog Converter) and no complex gate voltage generating circuit. Simple gate voltage generating circuit can also adapt to a wide range of external resistance changes. Because of the lower mismatch caused by threshold voltage mismatch, it can achieve a highly matched output current. The chip has only ±1.1% mismatch between different channels. The area of each channel's power MOS is only 200µm× 100µm. The area of analog part including current bias, bandgap reference, current mirror, and other control circuits is only 400µm×200µm.","PeriodicalId":6363,"journal":{"name":"2011 IEEE International Conference of Electron Devices and Solid-State Circuits","volume":"11 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2011-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81778021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
