注:
1、基硼電阻率和碳氧含量為保證值,生產廠應經常進行基硼電阻率的檢測,每年定期進行碳氧含量的分析
NOTE: Resistivity(B)and carbon/oxygen content are a guaranteed value,Carbon/oxygen
content should be analyzed at a fixed tine every year

2、N型少數載流子壽命值系指氫氣下檢驗工藝測試的壽命值
N-type minority carrier lifetine is the life value of the process check test in the hydrogen

3、需方如有特殊要求,供需雙方可另行協義
Both parties can negotiate according to the special requirements of buyers
