Furthermore , to avoid the craze of the target caused by the brittleness of si element , a new mold and cooling method have been developed . in the second part , the material of the resistor coatings has been studied 此外，为了防止靶材的破裂，降低其内应力，自行设计了熔炼模壳及冷却方法，有效的解决了靶材的开裂问题，使靶材熔炼的成品率达到90 %以上。
The cmos technology is better than bipolar technology , which help the circuit get lower power , so it is adopted . the hspice is used for dac circuit simulation with tsmc 0 . 18 m bsim3 ( v3 . 1 ) cmos model 从集成度、功耗、成品率等方面考虑, cmos工艺明显优于双极型工艺,故本设计采用cmos工艺,并用tsmc0 . 18 mbsim3 ( v3 . 1 ) cmos工艺模型在hspice软件上完成电路模拟仿真。
As the sealing technique and gas exhausting technique were carried out in the later manufacture stage , the technique result would relate to good finished ratio of fed , which is very important for the whole fed manufacture 由于封接及除气工艺在fed制造过程中属于后道工艺，它的成败直接影响到fed显示屏成品率高低，因而对整个fed显示屏的制造具有举足轻重的意义。
And machine adopt imported microcomputer control system , combining precise electric and air pressure operate system . it s easy to use , steady to run with low fault rate that make the rhinestones good smooth finish and high rate of finished products 本机采用日本进口微电脑控制，结构精密的电气动组合操控，使用方便，运行稳定，故障率低，产品光洁度好，成品率高。
In order to improve process quality and increase probability , we optimize ohm contact resistance and breakdown voltage of devices by adjusting process conditions . finally , dc - 500mhz midf switch is fabricated , in which some important conclusions and suggestions are introduced 工艺研究的重点是改进工艺质量，提高成品率，为此我们通过调整工艺条件来优化欧姆接触电阻和提高器件的击穿电压。
This dissertation aims at discussing income optimal model of parameter yield . based on design centering and maximum income approach , the author put forward a new global profit optimal model that grounds on 1c products " optimal classifying 本论文主要研究了集成电路参数成品率的效益协调优化模型，在中心值设计、效益极大化模型的基础上提出了一种基于产品最优分档的整体效益协调优化模型。
It is showed that there are intricate relations between the fuel amount and both the yield and the tumble strength of agglomerate , but no direct effect on the main economy and technology indexes of sintering production by the lime amount used in sintering 结果表明，必要的燃料用量是满足烧结矿同时具有较高转鼓指数和成品率的基本条件，生石灰用量不会对烧结矿的主要技术经济指标产生直接影响。
For the substrate of heavily boron doped wafer , it has been proved that oxygen concentration is increased and oxygen precipitation is enhanced by hb ( heavily boron - doping ) during crystal growth , which is beneficial for ig and therefore improve the yield of ulsi 另一方面，在相同的晶体生长条件下，重掺硼硅单晶氧含量升高，氧沉淀被增强，能形成有效吸杂点，提高硅片机械强度，抑制void缺陷，有利于提高ulsi的成品率。
