Definitions

  • the present disclosure relates to novel and advantageous rupturable membranes or what are often referred to as breakseals.
  • the present disclosure relates to novel and advantageous breakseals, methods of making the breakseals, and methods of using the breakseals in shipping and dispensing systems, such as those typically used for the storage, transport, and dispense of photosensitive reagents or other ultrapure chemicals used in the semiconductor manufacturing industry.
  • Container systems may be used in many industries for storing, shipping and/or dispensing materials of any viscosity.
  • numerous manufacturing processes require the use of ultrapure liquids, such as acids, solvents, bases, photoresists, slurries, cleaning formulations, dopants, inorganic, organic, metalorganic and biological solutions, pharmaceuticals, and radioactive chemicals.
  • ultrapure liquids such as acids, solvents, bases, photoresists, slurries, cleaning formulations, dopants, inorganic, organic, metalorganic and biological solutions, pharmaceuticals, and radioactive chemicals.
  • Such applications require that the number and size of particles in the ultrapure liquids be minimized.
  • semiconductor manufacturers have established strict particle concentration specifications for process chemicals and chemical-handling equipment.
  • a protective seal may be provided to, for example, seal in the contents of the container and prevent contaminants or light from being introduced into the container and thus the materials stored therein.
  • the seal may be a rupturable seal or membrane, or what is commonly referred to as a breakseal.
  • a breakseal is typically designed such that the breakseal does not rupture or break by impact or pressures commonly occurring for example, during transport and handling of the container, but substantially easily tears when punctured for example, by a dispense system connector for dispensing the contents of the container.
  • breakseals have been conventionally used.
  • a breakseal is formed as a two-layer structure, having a first layer of laminated low-density polyethylene (LDPE) foam and a second layer of polytetrafluoroethylene (PTFE) film, the two layers bonded together using an adhesive.
  • LDPE laminated low-density polyethylene
  • PTFE polytetrafluoroethylene
  • tear lines or score lines may radially extended from the center, such that when a dispense system connector is pressed against the breakseal for connection with the container, the tear lines permit the breakseal to tear.
  • the LDPE foam and use of adhesives in such breakseals can lead to undesirable contamination, and thus downstream defects, in certain manufacturing processes.
  • the adhesive material used to bond the two layers may be introduced into the material stored within the storage container, thereby reducing the purity of the material and causing problems in downstream processes.
  • Korean patent 20-0452250 titled “One Layer Break Seal,” which is herein incorporated by reference in its entirety.
  • the breakseal of Korean patent 20-0452250 has a circular plate shape made of a single layer of injection molded low-density polyethylene (LDPE).
  • LDPE injection molded low-density polyethylene
  • such breakseal is not without faults.
  • the breakseal of the Korean patent may be more difficult, and may take longer, to manufacture, each of which drives up manufacturing costs.
  • challenges in the molding process may be encountered during the manufacture of a molded breakseal of the shape and design as described in Korean patent 20-0452250.
  • a mold cavity having a relatively thick section would be required to mold the outer "donut shaped" rim of such a breakseal.
  • Sink which occurs when material shrinks away from walls of a mold cavity, is often associated with such thick sections of a mold cavity. Sink adversely affects the structural integrity of the breakseal, which in turn adversely affects the molded products ability to function as a protective seal.
  • breakseals and methods of making the breakseals for use in shipping and dispensing systems such as those typically used for the storage, transport, and dispense of photosensitive reagents or other ultrapure chemicals used in the semiconductor manufacturing industry.

Abstract

La présente invention se rapporte à un opercule cassable, et à un procédé de fabrication d'opercule cassable, possédant une première couche de film MDPE ou LDPE/LLDPE extrudé selon une forme de rondelle plate délimitant une ouverture centrale dans celle-ci et une seconde couche de film PTFE stratifiée à chaud sur un premier côté de la première couche. La seconde couche est exposée et peut se rompre dans l'ouverture centrale de la première couche. Selon certains modes de réalisation, la première couche se compose de deux sous-couches de film MDPE ou LDPE/LLDPE selon des formes de rondelle plate liées ensemble par stratification à chaud. Selon un autre mode de réalisation, un opercule cassable comprend une structure moulée à composant unique comprenant une partie rebord extérieur ayant une première épaisseur et délimitant une ouverture centrale dans celle-ci, et une partie opercule central ayant une seconde épaisseur inférieure à la première épaisseur, la partie opercule central s'étendant sur l'ouverture centrale et faisant corps avec la partie rebord extérieur.
