Description

晶粒双面筛盘
技术领域
本发明涉及微电子领域的一种半导体元器件的制造工具,具体地说是一种可以将GPP芯片按N端面和P端面交叉排列的晶粒双面筛盘。
背景技术
在半导体元器件生产制造中,其生产中的半导体晶片分N端面和P端面,常规筛盘无法区分出GPP芯片的N端面和P端面,且无法按工艺要求使筛盘上GPP芯片按N端面和P端面交叉排列,传统的操作工艺是通过从蓝膜上剥离,手工进行排列,操作手续复杂,且无法保证一致性、效率低容易出错。
发明内容
本发明的目的是克服现有技术的不足,提供一种能有效将GPP芯片的N端面和P端面交叉排列的晶粒双面筛盘。
本发明是通过以下技术方案实现的:
一种晶粒双面筛盘,由筛盘框和筛盘组成,筛盘位于筛盘框上面,其特征在于:晶粒双面筛盘由正面筛盘和反面筛盘构成,正反筛盘通过转轴相连接,反面筛盘通过转轴旋转180o与正面筛盘相复合,正面筛盘和反面筛盘呈轴对称,筛盘有纵横整齐排列的筛选孔,筛盘的筛选孔直径与所筛晶片的N面相同,筛选孔底部有排气孔,筛盘框为密闭空腔,排气孔与筛盘框密闭空腔相通;筛盘上筛选孔可设置纵向覆盖板可根据工艺需要覆盖筛选孔;所述的筛盘框侧面有吸气孔,吸气孔与真空泵相连。
本发明与现有技术相比具有以下有益效果:
1.区分极性成功率高;
2.可交叉极性排列;
3.操作方便,效率高。
附图说明
图1为晶粒双面筛盘结构示意图;
图2为GPP晶片所示图。
图中:筛盘框1、筛选孔2、吸气孔3、筛盘4、N面5、P面6、转轴7和覆盖板8。
具体实施方式
下面结合附图和具体应用对本发明的内容做进一步的描述:
如图所示为晶粒双面筛盘结构示意图,包括筛盘框1、筛选孔2、吸气孔3、筛盘4、N面5、P面6、转轴7和覆盖板8。晶粒双面筛盘由正面筛盘和反面筛盘构成,正反筛盘通过转轴相连接,反面筛盘可通过转轴旋转180o与正面筛盘相复合,为达到筛盘上晶片的排列为N面和P面交叉排列的目的,在正面筛盘的2、4、6列用覆盖板8覆盖,反面筛盘的1、3、5列用覆盖板8覆盖,将晶片在筛盘上摇动,使晶片的N面落入筛选孔2内,然后移去正面筛盘的覆盖板,将反面筛盘沿转轴旋转180o与正面筛盘相复合,释放反面筛盘吸气,使反面筛盘2、4、6列的晶片落入正面筛盘的对应筛盘孔内,晶片N面落入筛选孔2内是因GPP芯片P面要比N面要小得多,而且P面沟道刮玻璃粉后,平整度不及N面,人工摇芯片时,比重重的容易在下方,轻的在上方。为高效区分出芯片的极性P面 、N面。通过工程人员对GPP芯片的外观形状进行研究,芯片两边比重不一,在摇动筛板时,芯片撞击后,重的一侧容易被吸住,GPP芯片两面的面积有大小之分,P面在吸孔位置容易漏气,吸不住,吸住的一定是N面。区分极性成功率可达到99%。
