Subdivided semiconductor wafer separator
Abstract
Abstract THIS INVENTION RELATED TO A METHOD AND AN APPARATUS FOR SUPPLYING A PREDETERMINED SPACING TO INDIVIDUAL SEMICONDUCTOR PELLETS, SUBDIVIDED FROM A PARENT SEMICONDUCTOR WATER WITHOUT CHANGING THE RELATIVE ORIENTATION AND POSITION THE PELLETS OCCUPIED IN THE PARENT WAFER PRIOR TO THE SUBDIVISION. THE SEPARATOR COMPRISES A SHEET OF STRETCHABLE MATERIAL HAVING A MAJOR FACE ADAPTED TO SUPPORT AN ARRAY OF PELLETS, MEANS FOR HOLDING THE SHEET IN A TAUT CONDITION, AND MEANS ENGAGEABLE WITH THE SHEET FOR SIMULTANEOUSLY STRETCHING THE SAME IN TWO MUTUALLY PERPENDICULAR COORDINATES IN THE PLANE OF THE MAJOR FACE. THUS, WHEN THE STRETCHING OF THE SHEET IS INCREASED, THE SPACING BETWEEN THE PELLETS SUPPORTED ON THE SHEET ALSO INCREASES AND THERBY FACILITATES TREATMENT OF EACH INDIVIDUAL PELLET WITH MINIMIZED DISTURBANCE OF ITS NEIGHBOR,
