1.
何谓
PIE?
PIE
的主要工作是什幺
?
答:
Process Integration
Engineer(
工艺整合工程师
),
主要
工作是整合各部门的资源
,
对工艺持续进行改善
,
确保产品的良
率(
yield
)稳
定良好。
2.
200mm
,
300mm Wafer
代表何意义
?
答:<
/p>
8
吋硅片
(wafer)
直径为
200mm
,
直径为
300mm
硅片即
12
吋
.
3.
目前中芯国际现有的三个工厂采用多少
mm
的硅片
(wafer)
工艺?未
来北
京的
Fab4(
四厂
)
采用多少
mm
的
wafer
工艺?
答:当
前
1~3
厂为
200mm(8
英寸
)
的
wafer,
工艺水平已达
0.13um
工艺。未来
北京厂工艺
wafer
将使用
300m
m(12
英寸
)
。
4.
我们为何需要
300mm?
答:
wafer size
变大,单一
wafer
上的芯片数<
/p>
(chip)
变多,
单位成本降低
200
→
300
< br>面积增加
2.25
倍
,
芯片数目约增加
2.5
倍
5.
所谓的
0.13 um
的工艺能力<
/p>
(technology)
代表的是什幺意义?
< br>
答:是指工厂的工艺能力可以达到
0.13 um
的栅极线宽。当栅
极的线宽做的越小时,整个器件就可以变的越小,工作速度
也越快。
6.
从
< br>0.35um->0.25um->0.18um->0.15um->0.13um
< br>的
technology
改变又代表
的是什幺意义?
答:栅极线的宽(该尺寸的大小代
表半导体工艺水平的高低)
做的越小时,工艺的难度便相对提高。从
0.35um -> 0.25um -> 0.18um
->
0.15um -> 0.13um
代表着每一个阶段工艺能力的提升。
7.

oxide
(线形氧化层)
,
liner oxide
的特性功能为何?
答:
Liner
oxide
为
1100C,
120
min

SAB
是什幺的缩写
?
目的为何?
答:<
/p>
SAB
:
Salicide
block,
用于保护硅片表面,在

)
。
32.
何谓硅化物
( salicide)?
答:
Si
与

降低接触电阻值(
Rs,
Rc
)。
33.
硅化物
(salicide)
的形成步骤主要可分为哪些
?
答:①
Co(
或
Ti)+TiN
的沉积;

RTA
(快速热处理)来形成
Salicide
。
③将未反应的
Co(Ti)
以化学酸去除。
< br>
④第二次
RTA
(
用来形成
Ti
的晶相转化
,
降低其阻值
)
。
34.
MOS
器件的主要特性是什幺?
p>
答:它主要是通过栅极电压(
Vg
)来控制
源,漏极
(S/D)
之间电
流,实现其
开关特性。
35.
我们一般用哪些参数来评价
device
的特性?
p>
答:主要有
Idsat
、
< br>Ioff
、
Vt
、
Vbk(breakdown)
、
Rs
、
Rc
;一
般要求
Idsat
、
Vbk
(breakdown)
值尽量大,
Ioff
、
Rc
尽量小,
Vt
、
Rs
尽量接
近设计值
.
36.
什幺是
Idsat?Idsat
代表什幺意义?
答
p>
:
饱和电流
。
也就
是在栅压
(Vg)
一定时
,
源
/
漏
(Source/
Drain)
之间流动的最大电流
.
37.
在工艺制作过程中哪些工艺可以影响到
Idsat?
答:
Poly CD(
多晶硅尺寸
p>
)
、
Gate oxide Thk(
p>
栅氧化层厚度
)
、
AA(
有源区
)
宽度、
Vt imp.
条件、
LDD
imp.
条件、
N+/P+ imp.
条件。
38.
什幺是
Vt? Vt
代表什幺意义?
答:阈值电压(
Threshold
Voltage
),就是产生强反转所需的
最小电压。当栅极电
压
Vg
时
, MOS
处于关的状态,而
Vg
〉
=Vt
时,源
/
漏之
< br>间便产生导电沟道,
MOS
处于开的状态。
39.
在工艺制作过程中哪些工艺可以影响到
Vt?
答:
Poly
CD
、
Gate oxide Thk. (
< br>栅氧化层厚度
)
、
AA(

答:关态电流,
< br>Vg=0
时的源、漏级之间的电流,一般要求此电
流值越
小越好。
Ioff
越小
,
表示栅极的控制能力愈好
,
可以避免
不必要的漏电

(

)
。
41.
什幺是
device breakdown
voltage?
答:指崩溃电压(击穿电压),在
Vg=Vs=0
时,
Vd
所能承受的<
/p>
最大电压,当
Vd
大于此电压时,源、漏
之间形成导电沟道而不受栅压的影响。
在器件越做越小的情况下,这种情形会将会越来越
严重。
42.
何谓
ILD? IMD?
其目的为何?
答:
ILD
:
Inter
Layer
Dielectric,
是用来做
device
与
第
一层
metal
< br>的隔离(
isolation
),而
IMD
:
Inter Metal Dielectric
,是用来
做
metal
与
metal
的隔离(
isolation
)
.
要注意
ILD
及
IMD
在
CMP
后的厚度控
制。

43.
一般介电层
ILD
的形成由那些层次组成?
答:①
SiON
层沉积
(
用来避免上层
B,P
渗入
器件
)
;
②
BPSG
(掺有硼、磷的硅玻璃)层沉积;
③
PETEOS
(等离子体增强正硅酸乙脂)层沉积;
最后再经
ILD Oxide CMP(SiO2
的化学机械研磨
)
来做平坦化。
44.
一般介电层
IMD
< br>的形成由那些层次组成?
答:①
SRO
层沉积
(
用来避免上层的氟离子
往下渗入器件
)
;
②
HDP-
FSG
(掺有氟离子的硅玻璃)层沉积
;
③
PE-FSG
(等离子体增强
p>
,
掺有氟离子的硅玻璃)层沉积;
使用
FSG
的目的是用来降低
dielectric k
值
,
减低金属层间的寄生电容。
最后再经
IMD Oxide CMP(SiO2
的化学机械研磨
)
来做平坦化。
45.
简单说明
Contact(CT)
的形成步骤有那些
?
p>
答
:
Contact
是指器件与金属线连接部分
,
分布在
poly
、
AA
上。
< br>
①
Contact
的
Photo
(光刻);
②
Contact
的
Etch
及光刻胶去除
(ash & PR
strip)
;
③
Glue
layer
(粘合层)的沉积;
④
CVD
W
(钨)的沉积
⑤
W-CMP
。
46.
Glue
layer
(粘合层)的沉积所处的位置、成分、薄膜沉积
方法是什幺?
答:因为
W
较难附着在
Salicide
上
,
p>
所以必须先沉积只
Glue
layer
再沉积
W
Glue
layer
是为了增强粘合
性而加入的一层
。
主要在
salici
de
与
W(CT)
、
< br>W(VIA)
与
metal
之间
,
其成分为
Ti
和
TiN,
分别采用
PVD
和
< br>CVD
方式制作。
47.
为何各
金属层之间的连接大多都是采用
CVD
的
W-plug(
钨插
塞
)?
答:①
因为
W
有较低的电阻;
②
W
有较佳的
step coverage(
阶梯覆盖能力
)
。
48.
一般金属层
(metal layer)
的形成工艺是采用哪种方式
?
